This invention is applicable, for example, DVD (digital versatile disk). In particular, in accordance with this invention is provided access to the individual information management through the guide information for the extended file, and the identification code indicating the type of the corresponding extended file, and information about the format of the record in information management are located in the guide information of the enlarged file to extend recording capacity of the disk to be able to write also a file of still pictures other than the file of moving images.

This invention claims the priority of patent application of Japan No. 2002-134045, filed may 9, 2002, the full content of which is included in this description.

The level of technology

Usually as an optical disk storage used DVDs, including DVD with recording capability (digital versatile disks), such as DVD-R (DVD-drive with the possibility of recording the), DVD-RW (DVD-drive with a rewritable) and DVD-RAM (DVD-drive with random access memory). These DVDs, DVD-R and DVD-RW discs containing Not recorded, the video data format corresponding to the video DVD can be played back using designed only for playback of DVD player or computer for video playback.

Figure 1 shows a graphical diagram illustrating based on the video format DVD logical format of the optical disc. As shown in figa, an optical disk containing a logical format, according to the video format the DVD has its own area for recording information, divided into an area called "enter"on the interior of its circumference, area and data area, called the conclusion, on the outer circumference. The optical disk contains the desired video data or the like recorded in the data area.

As shown in figure 1, the data area includes the area of the UDF (universal disk format) A1 (area system files), the VMG area management (video) A2 (area of information management DVD) and the area A3 record data in real time in order from a zone input. Region UDF and VMG are provided for recording the management information used to manage the video files recorded on this optical disk. Of these areas, UDF and VMG VMG area A2 refers to the DVD player and EET recorded therein information of the TOC (table of content) used to manage all of the video data recorded in the area A3 record data in real time. On the other hand, the UDF area A1 is designed to manage files using the computer and contains therein the management information used to manage all of the video data recorded in the area A3 recording real-time data in a format compatible with the computer control system.

As shown in figv, area A3 recording real-time data is an area programs, which are subject to recording actual data, and contains recorded therein video data in blocks of VTS (set of videomature, referred to in the following simply as "name", where this is appropriate). It is also important to note that, as shown in figs, VTS consists of VTSI (information set videomature), VTSM deviations, VOBs (set of video objects in VTS), VTSTT deviations, VOBs (set of video objects for titles in a VTS) and VTSI BUP (backup of VTSI) in this sequence. VTSTT deviations, VOBs are recorded in the form of video data in MPEG-2 format (expert group on the moving image as video data in real time, VTSI is written as the address information, etc. for managing video data, educated real data, and VTSTT deviations, VOBs contains menu titles recorded video data. It should be noted that VTSTT deviations, VOBs is not mandatory, and VTSI BUP is with the fight a backup of VTSI.

When the computer accesses the specified optical disk, the desired file can be searched on the basis of the UDF to play. When the optical disc is a DVD player, finding a desired file can be done on the basis of VMG to play. Namely, UDF supported by the file management system of the computer to control the video data recorded on the optical disk, while the VMG is supported by the DVD player to control the video data recorded on the optical disk.

Video data recorded on an optical disk or by using an incremental recording mode (called in the following way INC) or way restricted overwrite (called in the following way ROW). Way INC is a progressive video recording, while the method ROW is used in optical discs, made rewritable. However, in the method ROW video data to be recorded in net (not recorded) area, also written sequentially. In these methods, INC and ROW region RMA (control account)formed along the inner circumference zone input, provides the management area, such as padding (for a detailed description of which will be given below) or similar

Figure 2 shows a graphical diagram for explanation of the recording process on the basis of STRs is both ROW. In the method ROW reserved area of the input region UDF and VMG and area for recording VTSI and VTSM deviations, VOBs first names by filling, as shown in figa. It should be noted that under the "filling" means the booking process area by writing arbitrary data, such as zeros or similar

In the way that ROW, when reserved these areas consistently recorded video data to set VTSTT deviations, VOBs real data, as shown in figv. After recording the real data under one name sets the scope of the VTSI BUP and filled to reserve areas account for VTSI and VTSM deviations, VOBs following names, as shown in figv. Thus, the job areas VTSI and VTSM deviations, VOBs for recording real data is repeated again first, as shown in figs. Thus, recorded one VTS by using method ROW on the optical disk.

In the method for continuous ROW write the following names of actual data is recorded by following the filled area formed by the previous VTS, to specify areas VTSTT deviations, VOBs and VTSI deviations, VOBs, and then is filling in for the backup of VTSI and VTSM deviations, VOBs subsequent names, as shown in fig.2D. Then you set the field for VTSI and VTSM deviations, VOBs names, as shown in figa, for recording thereby following VTS on the optical disk, as shown in fig.2F. In the method ROW for sledovatelei account names is the same filling for sequential write VTS.

On the other hand, in an optical disc containing recorded therein VTS, to set the recording area data in real-time way ROW specifies the field UDF and VMG through completion and then the area of the input zone and the output, as shown in fig.2G, for compatibility with the optical disk to read-only. It should be noted that the area of the UDF and VMG are set via a data generation UDF and VMG of the VTSI and VTSM deviations, VOBs data names and write data in the initial region of the inner circumference of the through completion.

In published by the Japan patent No. 2002-063765, 2001-148166 and 2002-56609 offered to write the upper address VTSI corresponding to the management table formed along the inner circumference of the optical disk in accordance with the account names, to control the scope of programs in accordance with the management table for recording file of moving images and thus provide access to each name based on the table management even at the stage before completion.

This optical disc can be played back instead of the magnetic tape in the portable recording camera. In this case, because some conventional video camera recorders can record both moving images and still images, an optical disk for use in a portable recording camcorder wish is Ino should be able to record still images, and not just moving images.

A possible approach to solving this problem is to write files moving and still images on an optical disk by recording moving images in DVD video format and control information for moving images in the field of UDF and VMG and write another file (in this case, the file still images), different from the file of moving images - only in the region of the UDF. Thus, it is considered that the file management system of a computer or the like based on the UDF, so that the computer can play all the files recorded in the recording area of real-time data, which is an area programs. It is also considered that the DVD player is based on the VMG, so that it can write to these files other than the files of moving images, without affecting the reading of the DVD player.

In addition, it is also possible that the management information for each file needed for this UDF, temporarily saved with the file still images on an optical disk, as he later will not be completed.

However, the optical disk of this type, because it has a large storage capacity, can be used not only in recording the camcorder instead of magnetic tape, but can also be used in a variety of devices or systems for recording, other f is low, different from the files moving and still images, and to manage recorded files in accordance with the management information used in each of such devices or systems.

In this case, assuming that the format of the control information is set for each relevant file whenever you add a file record type, you must specify the management information, which makes it difficult to write procedure is additionally a new file in the optical disk.

It should be noted that in the case of the use of such an optical disk without specifying this format of management information of the optical disk is completed so that the file management system on the basis of the UDF management file of this type is in the directory structure, for which the file is not suitable.

The invention

The purpose of this invention is to overcome the above drawbacks of the conventional recording device using an optical disk as the recording media, by creating a new recording device and the recording method using the recording media.

Another purpose of this invention is to eliminate the above disadvantages of the prior art by creating a recording device and recording method using the recording medium, recording program on which I write the file on the recording medium and the recording media, having recorded therein the program records to ensure sufficient expansion of the recording capacity of the disc for recording also file of still pictures other than moving pictures.

These goals can be achieved through a recording device and recording method using the recording media according to this invention, in which advanced file separate from the file of moving images, formatted to allow reading specialized playback device for the recording medium, is recorded in combination with separate information for the extended file area of the recording media; a guide information for the extended file including at least an address of a specific management information, is recorded on the recording media; address the guiding information for the enhanced file is written in the management table; and the identification code indicating the type of the extended file the corresponding individual control information and the recording format in information management are located in the guide information of the extended file.

In the program recording method for recording a file in the recording media according to this invention, the extended file separate from the file of moving images, formatted to provide the of reading with the help of specialized playback device for recording media, recorded in combination with the individual management information for the extended file area programs of the recording medium; a guide information for the extended file including at least an address of a specific management information, is recorded on the recording medium; address guide extended information file is recorded in the management table; and the identification code indicating the type of the extended file in the corresponding individual control information and the recording format in information management are located in the guide information of the extended file.

The specified program is recorded using the recording method according to this invention.

In the recording device and the recording method according to this invention, the extended file separate from the file of moving images, formatted for playback via a dedicated playback device for recording media, recorded in combination with management information for the extended file area programs; guide information for the extended file including at least an address of a specific management information, is recorded on the recording medium; address guide extended information file is recorded in the management table; and the identification code indicating the type of the extended file, in compliance is the fact that individual control information, and the address of the control information are arranged in the guide information of the extended file, which advanced file separate from the file of moving images specified in the DVD video, you can record formatted in accordance with the video format DVD optical drive, so you can get the type of the extended file and record format of the individual information management for advanced file from the guide information of the extended file. Thus, when additionally recorded a new advanced file fails any modification of the recording format of the individual information management. For example, you need to change only the identification code indicating the type of the extended file. Therefore, you can increase the recording capacity of the disk, for example, to write files, still images, etc. that are different from the files of moving images.

Detailed description of the invention

Below is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

Figure 3 shows the block diagram of the first variant implementation of the optical disc drive according to this invention. The optical drive is indicated in General position 1. This drive 1 optical drive is a portable recording camcorder, is made with the possibility of recording the image on the optical disk, which is a DVD.

In particular, the actuator 1 of the optical disk shown in figure 3, contains the block 3 video input, which performs analog-to-digital conversion of video signals obtained by means of the image (not illustrated), or video signals supplied from an external device to generate video data. It should be noted that many tools produce images that are integrated in the drive 1 optical drive, controlled by a Central processing unit (CPU) 4, which is also found in drive 1 optical drive, to obtain the results of shooting moving images and still images. Thus, block 3 video input operates in accordance with control carried out by the CPU 4 by means of image acquisition, for selective reception of video data consisting of data of a rolling picture is or still image.

The actuator 1 of the optical disk further comprises a block 5 input audio, which performs analog-to-digital conversion of audio signals received by the microphone, and audio signals supplied from outside, to generate audio data.

Drive 1 optical drive also contains a block of 6 compression/deployment, operation mode which is changed under the control of the CPU 4 for data processing for recording or playback. In particular, for recording video and audio data supplied from the input unit 3 video input unit 5 audio input, respectively, block 6 compression/deployment uses a RAM 9 for multiplexing video and audio data through compression and delivers the data to the processor 7 title information. Conversely, for playback of video and audio data from the optical disk 52 unit 6 compression/deployment also uses RAM 9 to separate the data supplied from the CPU 7 title information, the video and audio data, and then deploys the video and audio data, respectively, and generates detailed data.

In particular, to write data to the video processor 8, as contained in section 6 of the compression/deployment, managed by the CPU 4 to compress the video data supplied from the input unit 3 video input, and outputs compressed data. At this time, if the video data is moving image data, block 6 compression/resort the cation uses MPEG-2 for video compression and in the case if video data are data of still images, block 6 compression/deployment compresses the data in the JPEG format (joint expert group on pictures) and outputs compressed data. To playback the data processor 8 also deploys video data from the output of the multiplexer 10 in accordance with the MPEG or JPEG, which were compressed data, and generates detailed data.

To write data to the audio processor 11, is contained in section 6 of the compression/deployment, compresses audio data supplied from the output of block 5 input audio format MPEG audio format Dolby or linear format, pulse code modulation, and outputs the compressed data. Conversely, for data playback audio processor 11 expands the audio data supplied from the multiplexer 10, and generates detailed data.

In addition, to write data to the multiplexer 10 performs multiplexing with distinction-time video data output from the video processor 8 and the audio data output from the audio processor 11 and outputs the multiplexed data to the processor 7 title information. Conversely, to playback the data multiplexer 10 divides the multiplexed time-shared data from the output of the processor 7 title information on the video and audio data, and supplies these data to the video processor 8 and the audio processor 11, respectively.

The actuator 1 on the optical disk also contains the monitor unit 12, made of display devices for controlling the video data supplied from the input unit 3 video input, audio data supplied from the block 5 input audio or video data and audio data supplied from the block 6 compression/deployment, and device processing of the audio data. Thus, the actuator 1 of the optical disk according to this invention, may be controlled to capture images and sounds, and the results of the playback data.

Drive 1 optical disc includes a video/audio encoder 13, which compresses video and audio data supplied from unit 3 video input unit 5 audio input, respectively, or video and audio data supplied from the block 6 compression/deployment in specified formats, respectively, and outputs data to the external device. Thus, the actuator 1 of the optical disk according to this invention, provides control of the captured images and sounds and playback results in the external device.

To write data to the processor 7 title information served multiplexed time-shared data supplied from block 6 compression/deployment, and it adds to the multiplexed time-shared data title information unique to the DVD, the title information or the like to the file extension, detailed description of which will be PR is included below, under the control of the CPU 4, and outputs data. In addition, in accordance with the information supplied from the CPU 4, CPU 7 title information creates data such as UDF, VMG, VTSI and so on, and outputs these data to the processor 14 DVD signals. To playback the data processor 7 title information is separated from the output from the processor 14 signals DVD title information added during recording, and outputs it to the block 6 compression/deployment, and reports separated the title information in the CPU 4. It should be noted that advanced file" is a file that is not specified in the standard video format DVD-standard optical disk 2, and in this embodiment, the format still image is used as an extended file.

To write data to the processor 14 signals the DVD uses a RAM 15 for generating error correcting code from the output processor 7 title information and adds error correction code to the output. In addition, the processor 14 signals DVD performs scrambling, modulation 8/15, etc. and outputs a data chain consisting of processing results in the form of a serial chain data in analog block 16 on the external interface.

Conversely, to playback the data processor 14 DVD signals, performs error correction, decoding and descrambling output of anal is the final block of 16 external interface, namely handles the output in reverse order relative to the order processing procedure data and outputs the results of such processing in the processor 7 title information. In addition, the processor 14 signals DVD performs d / a conversion information of the drive such as the management of the spindle, management, tracking, controlling the focus and management of the sled, the data supplied from the CPU 4 to create such actuator signals, and transmits signals to the drive amplifier 18 for electric motors.

Analog block 16 external interface generates the control signal by the amount of light for the laser beam that is subjected to radiation from the laser head 19 on the optical disk 2, and issues a control signal. For playback of analog data block 16 external interface supports in accordance with the control signal by the amount of light intensity of the laser beam projected on the optical disk 2 from the optical head 19 at a constant value for reading data. Conversely, to write data to the analog block 16 external interface changes the signal level control amount of light in accordance with the output of the processor 14 signals of DVD, to increase the intensity of the laser beam is variable from values to playback the data up to the size of the write data according to the accordance with the output of the processor 14 DVD signals.

In addition, the analog block 16 external interface amplifies and processes the measurement result of the returned light from the optical head 19 to generate a reproduced signal whose level is changed in accordance with the chain of recesses (pits)formed on the optical disk 2, and processes the playback signal for the binary differentiation with the aim of obtaining reproducible data that are fed into the processor 14 DVD signals. By means of the above processing of the measurement result returned light analog block 16 external interface generates the error signal of the tracking error signal, the focus levels are changed in accordance with the values of the error tracking and focusing errors, respectively, and outputs these signals in the form of a digital signal to the CPU 4.

The amplifier 18 to the motor receives the drive signals from the processor 14 DVD signals and activates mechanisms in accordance with the drive signals. In particular, the amplifier 18 to the motor causes the rotation of the motor spindle 20 and the motor 21 of the slide using one of these drive signals to control the spindle and control the sled. In addition, the amplifier 18 to the motor actuates the actuating device installed in the optical head 19, by using the drive is Ignatov to control the tracking and management focus, respectively.

The engine 20 of the spindle produces capturing optical disk and causes it to rotate at a given speed. The engine 21 of the slide moves the optical head 19 radially with respect to the optical disk 2.

Receiving the control signal by the amount of light from the analog block 16 on the external interface, the optical head 19 emits a laser beam from the semiconductor laser integrated in it, and focuses the laser beam over the area of the recording information of the optical disc 2 through the objective lens. The returned light, namely, the reflected part of the laser beam projected on the optical disk 2, is sent to the specified element of the photodetector of the optical head 19 through the objective lens, and the measurement result of the light is fed into the analog block 16 on the external interface. The objective lens of the optical head 19 mounted for movement with the actuator, which is driven by the control signals tracking and focusing, to control tracking and focusing. In addition, the intensity of the laser beam alternately increases in accordance with the control signal quantity of light, thereby locally increasing the temperature of the recording area information of the optical disk 2 to record in this place the desired data.

The CPU 4 is provided as to what stroller system for drive 1 optical drive. Through the implementation of programs pre-installed in drive 1 optical drive, signal operations from user control panel (not shown) and receiving various signals measured analog block 16 on the external interface, the CPU 4 controls the operation of each of the constituent blocks. In particular, the CPU 4 receives the error signal of the tracking error signal, the focus of the measured analog block 16 on the external interface, to generate information for controlling the drive of the focus and tracking, converts these signals using the processor 14 DVD signals into analog signals and supplies the analog signals to the amplifier 18 for electric motors, which in turn controls tracking and focusing of the optical head 19. In addition, when receiving the title information detected by the CPU 7 of the title information, the CPU 4 measures the position of the projected laser beam, generates the management information of the drive carrier out of the measurement result and delivers the information to the processor 14 DVD signals in order to perform thereby search, etc. in a Similar manner, the CPU 4 performs the drive control.

Above was a description of the main operations performed by the CPU 4 from the optical disk 2. Below is a description with reference to figure 5 of the operations performed by CPU 4 to the cityware or write data after the drive enable 1 optical drive. At step SP1 include drive 1 optical drive. Then, the CPU 4 performs the transition from step SP1 to step SP2, where it determines based on the detection of the optical disk 2 by using a detection mechanism (not illustrated)whether the optical disk 2 in the CD-ROM drive. If the result of determination at the step SP2 is negative (optical disk 2 is not installed), then the CPU 4 repeats the operation of step SP2. Conversely, when the drive 1 optical drive included with the set in place of the optical disk 2, or when the optical disk 2 is installed after the drive enable 1 optical drive, i.e. when the result of this determination is positive (optical disk 2 set in place), then the CPU 4 proceeds from step SP2 to step SP3. It should be noted that if the drive 1 optical drive turns off when the CPU 4 repeats the operation at step SP2, the CPU 4 proceeds directly to step SP4, where he comes out of this procedure of recording or playback (off power).

At step SP3, the CPU 4 operates the motor 21 of the slide for moving the optical head 19 to the inner circumference of the optical disk 2, and receives the result of the reading area on the innermost circumference of the processor 14 DVD signals. In the case where the optical disk 2 is completed by the disk, the CPU 4 retrieves the data field is t VMG from processor 14 DVD signals. Conversely, if the optical disk 2 is not completed by the disk, the CPU 4 receives the information area RMA from processor 14 DVD signals. When the CPU 4 based on the information region of the RMA specifies that the data is already recorded in the recording area of real-time data from an optical disc 2, it searches the optical disk data VTSI and VTSTT deviations, VOBs in each VTS. Thus, as in the optical disc drive for recording and playback of a normal DVD, the CPU 4 receives the management information required to write data and to read data from the optical disk 2.

In this procedure, the CPU 4 receives the data of the VMG area, and data area of the UDF. When reading the recording area of real-time data, the CPU 4 also receives the intermediate management information, if it is recorded in the recording area data in real time. Thus, the CPU 4 receives information management for advanced file not defined in the DVD video format, to ensure read extended file from the optical disk 2. The CPU 4 writes and maintains the sequence thus obtained control information in the internal memory.

Then, the CPU 4 proceeds to step SP5, where it determines whether it has a command to eject an optical disc. When the result of determination is positive, the CPU 4 sends the command to zagruzochnykh (not shown) to eject the optical disk 2, and then goes back to the step SP2.

Conversely, when it receives from the user a command other than the command to eject the optical disk 2, the CPU 4 proceeds from step SP5 to step SP6, where he defines what team he is from the user: on the record (REC), playback (PB) or off. When the user command is a command PB (playback), then the CPU 4 proceeds from step SP6 to step SP7, where he plays the file from the optical disk 2, and then returns to step SP5.

When the user command is a command REC (record), then the CPU 4 proceeds from step SP6 to step SP8, where he performs recording moving or still images on the optical disk 2, and then returns to step SP5. It is important to note that when the optical disk is set in it due to the so-called completion of the field UDF and VMG, the CPU 4 jumps through the procedure at step SP5, since the optical disk 2 was treated with write protection data. Thus, if the optical disc 2 is a DVD-RW which is finalized, but made with the possibility of Erasure, the CPU 4 erases existing data on the optical disk 2, with the knowledge of the user, and writes the data.

When the user command is a command to switch off the power supply, the CPU 4 proceeds from step SP6 to step SP9, where he performs the power supply is rivada 1 optical drive, and then returns to step SP4, where he comes out of the procedure of recording or playback.

When recording in one of the above procedures, when the optical disk is DVD-R, CPU 4 uses the method INC to record rolling file or a still image on the optical disk 2. On the other hand, when the optical disk is DVD-RW or DVD-RAM, CPU 4 uses the method ROW to record the rolling file or a still image on the optical disk 2.

On figa-5H shows a graphical layout of a recording file of the moving image and the still image file to an optical disc that does not contain even recorded in its files, namely, blank disc, using the method ROW. When updating the RMA information obtained from the optical disk 2, and stored in the internal memory of the CPU 4 performs the filling to reserve areas UDF and VMG on the optical disk 2. In addition, when the user command on the file entry of the moving image, the CPU 4 sets by filling the field VTSI and VTSM deviations, VOBs following names on the optical disk 2, as shown in figa. In addition, using these operations, the CPU 4 updates the RMA data held in his memory.

When receiving commands from a user to start recording the CPU 4 sequentially writes the actual data in the file of the moving image is agenia to define the scope VTSTT deviations, VOBs, then generates the management information including the location address start recording, the file size, the date of recording, etc. and writes the management information to define the scope VTSI BUP. To record subsequent titles CPU 4 reserves, by filling the field VTSI and VTSM deviations, VOBs names, as shown in figv. Then, the CPU 4 sequentially writes the management information, starting with the position on a given number of regions, backward from the position where he started recording VTSTT deviations, VOBs, to specify areas VTSI and VTSM deviations, VOBs, completing the recording of the same name, as shown in figs. In these operations, the CPU 4 writes and maintains the management information for the name in his memory.

For the next moving image, the CPU 4 similarly controls the operation of each of the constituent blocks for sequential write of files of moving images by using method ROW, as in a conventional optical disc drive.

During these operations, the CPU 4 accordingly updates the RMA data held in his memory, and overwrites the RMA on the optical disk 2 by using RMA data held in his memory at the time of ejection of the optical disk 2, power etc. Thus, even if the recording memory is lost, the drive 1 optical drive capable of access subject to completion op the practical disk 2 based on the recorded RMA.

It should be noted that the CPU 4 performs the above operations through the appropriate update of the management table stored in memory. It should also be noted that the table control is indicated on figure 5 the position of the TV.

It should be noted that table TV control is designed to control the scope of the programs on the optical disk 2, and may contain upper and lower addresses VTS recorded in the field programs, and area not available for any optical drive only for playback (DVD player), are listed in table TV control.

Thus, the CPU 4 writes on the optical disk 2, the upper and lower address corresponding table, TV control, stored in its memory, by writing VTS on the optical disk 2, and updates the table TV control on the optical disk 2 in accordance with table, TV control, held in his memory, during free time, and during ejection of the optical disk 2.

When receiving commands from a user to record a still image, the CPU 4 sets the position to start recording the real data at the top of the area reserved by filling. In addition, when receiving a command from the user to start recording the CPU 4 sequentially writes the still-image files, which are files extensions (indicated by position is a s EF figure 5), as shown in fig.5D. In addition, the CPU 4 sequentially generates the intermediate management information for temporary control of files of still images to completion in accordance with the record of files of still images and stores the information in its internal memory.

In addition, after recording the desired number of files of still images and when receiving a command from the user to finish recording the still-image files, the CPU 4 converts the intermediate management information contained in the memory, the recording format of the optical disk 2, and writes the intermediate management information in reserved by filling a region for recording VTSI and VTSM deviations, VOBs following names, as shown in fig.5D. Thus, the CPU 4 creates the management information for all files in the extension, subject to sequential writes. In addition, the CPU 4 selects the recording format in accordance with the characteristic of the file by the file entry of the moving image, in combination with appropriate management information in the order information management file of the moving image and information management, while recording advanced file in combination with the corresponding intermediate management information in order of advanced file and intermediate management information, and to record and intermediate management information collectively for multiple files.

Thus, to write the next file of the moving image, the CPU 4 writes VTSTT deviations, VOBs and VTSI BUP using real data in the field that is reserved by filling, and then reserves the following areas by completing and writes VTSI and VTSM deviations, VOBs again first, to write thus of the same name, as shown in figa-5G. In addition to recording the still-image files, the CPU 4 writes them in the same way consistently back at the top of the fill for recording management data and then reserve area by filling. In addition, when receiving a command from the user to complete the CPU 4 sets the field UDF and VMG areas and input and output in accordance with the management information, as shown in fign.

The CPU 4 updates the table TV control using these files of moving images in accordance with the record of names of files of moving images. On the other hand, for a file extension, the CPU 4 generates the guide information for file extension when each record intermediate data DK control in the optical disk 2, and updates the control information in THE extended information in a fixed region along the inner circumference of the optical disk 2 by using the guide information of the extended file. It should be noted that the "fixed region" means the AET specified area for recording the guide information, THE extended file. In this embodiment, the area originally reserved by filling, clean the area where there are UDF and VMG, is used as the "fixed region". In addition, the CPU 4 writes the upper and lower addresses of guidance THE advanced file into a table in the TV control.

It should be noted that the CPU 4 in fact performs the above operations through the use of its memory during the reading and updating of the optical disk 2 at the time of ejection of the optical disk 2, the power is turned off and in their spare time. In addition, the upper address of the guide information of the extended file is written only once in the table TV control during the recording of the first intermediate data DK management, as guide information THE extended file is recorded in a fixed area.

Thus, in the drive 1 optical drive you can find the guide information TE advanced file in accordance with the recorded TV table control and you can search each advanced file in accordance with the guide information of the extended file, so that the desired extended file can quickly find without scanning the entire area of the recording information in the optical disk 2. The guide information of THOSE rasshireniya can also be found in accordance with table TV control for files of moving images, so it is possible to effectively use the recording information.

It should be noted that intermediate information DK management needed to read extended file, and that it consists of characteristic information as an extension indicating the characteristic of an extended file, address information indicating the address where written extended file information file size indicates the size of the extended file, the time information indicating the date and time was recorded by advanced file in the optical disk, etc. As shown in figa-6D, the intermediate information DK management includes in its early information CI control for the set of files EF1-EF3 still images recorded sequentially after information CI management. It should be noted that information CI management includes identification information that indicates the category, catalog, etc. files that are managed in accordance with the individual information EXF1-EXF3 included after the management information that makes it possible to maintain compatibility files with the file management system of the computer.

Private information EX is a separate information management, consisting of the name of the file, the address of the beginning of the file, etc. Guide information THE extended file is the guide information that includes adresele information management, and includes the identification code, an address pointer indicating the address information CI management, which is also the address of the beginning of the intermediate data DK management, etc.

Thus, as shown in figa, when you write one title (VTS#1) for a file of the moving image, the CPU 4 writes the upper and lower addresses of the names in the table TV control in accordance with the record of this title (VTS#1). When these conditions are written three files EF1-EF3 still images in JPEG format, the CPU 4 writes information CI of information EXF1-EXF3 for files EF1-EF3 still images to record intermediate data DK management. The CPU 4 also writes the guide information to THE extended file, and updates the table TV control in accordance with the record of the guide information TE. It should be noted that the CPU 4 performs these operations by updating or other processing of relevant information held in memory, and actually updates the record in the optical disk 2 at the time of ejection of the optical disk 2, or at any other time. This also applies to subsequent stages of work.

When erased, the second recorded file EF2 still image, the CPU 4 detects that the guide information to THE extended file issuesi in table TV control and detects the address of the corresponding intermediate data DK management from the guide information TE, as shown in figv. After the discovery of the address of the CPU 4 changes the individual information EXF2 using file EF2 fixed image remaining in the optical disc 2, with a valid erase private information EXF2 or by setting the individual information EXF2 flag that indicates that certain information EXF2 is irrelevant information for the installation and thus the recording area of the file EF2 still image as a non-recorded area. It should be noted that in this case, the CPU 4 updates the intermediate information DK control by writing on top of all the intermediate data DK of the control.

When receiving commands from a user to record the still image file, if erased before this file EF2 still image is used for recording on top of the not-recorded region, the CPU 4 detects similarly guide THE file extended file entry in the table TV control address corresponding to the intermediate data DK management from the guide information TE, as well as the address that is installed as a non-recorded region of the recording information EXF22 in the intermediate data DK of the control, as shown in figs. Thus, the CPU 4 writes the file EF22 a still image associated with the team is isolates, in found not recorded region and writes on top of the information CI of information EXF1, EXF22 and EXF3 associated with files of still images EF1, EF22, and EF3, respectively, thereby updating the record intermediate data DK management. In addition, when receiving the user command to erase a file EF22 a still image, the CPU 4 sets the scope of the record file EF22 still images not recorded as a region, as discussed above in relation to figv.

The microcomputer writes the intermediate information DK control as described above. For writing the intermediate data DK management through additional entries advanced file CPU 4 generates intermediate information DK control for all the intermediate data DK management for file extensions that are already recorded on the optical disk 2, and writes the intermediate information DK1 control on the optical disk 2, as shown in figa and 7B. In addition, the CPU 4 updates the guide information TE advanced file to match the recording intermediate data DK1 control.

On figa shows the recording file EF4, EF5 and EF6 after a recorded title (VTS#2) shown in figa conditions. In this case, the CPU 4 generates information CI of information EXF1-EXF6 for information CI control the value of the intermediate data DK management for files EF1, EF2 and EF3 still images held in memory, and information such as addresses of files EF4, EF5 and EF6 still images, records the generated information CI of information EXF1-EXF6 in the optical disk 2, and also updates the guide information to THE extended file.

Thus, the CPU 4 updates the existing record files EF1, EF2 and EF3 still images in the optical disk 2, so that access is provided to them on the basis of individual information EXF1-EXF3 in accordance with the above newly recorded intermediate information DK1 management. As shown in figv, the CPU 4 updates or deletes new recorded files EF4-EF6 still images, as well as already recorded files EF1-EF3 still images by processing the individual information EXF1 - EXF6 in accordance with the new recorded intermediate information DK1 control.

Thus, when receiving a user command to complete the optical disk 2 having recorded therein the specified file extension, the CPU 4 generates UDF data from the control information (VTSI and VTSTT deviations, VOBs) names generated on the basis of the control tables and the intermediate data for all extension files, and writes the data UDF on the optical disk 2, as shown in fign. In addition, the CPU 4 generates data VMG only from the information Desk is based (VTSI and VTSTT deviations, VOBs) for all names and writes them on the optical disk 2. It is important to note that the data UDF and VMG are generated in accordance with the intermediate management information held in the memory or the like in Addition, after recording such data UDF and VMG CPU 4 sets the zone input and output. It should be noted that the CPU 4 writes the data UDF and VMG, specifies the zone input and output, and writes the intermediate management information by giving the corresponding data to the processor 14 DVD signals.

Therefore, in this embodiment, the UDF data management computer includes information management, which can be used to recognize advanced file and access it, but the data VMG to control playback of a DVD disc does not contain information related to file extension. In this procedure, the CPU 4 performs not visible to the user, similar to the VTSI, VTSM deviations, VOBs names the intermediate file management information that does not matter when playing back an optical disc 2 using the computer, so that consequently improves the controllability of the actuator 1 of the optical disk.

Thus, a common drive for DVD can read only files of moving images recorded on the optical disk 2 through the recording VMG data on the optical disk 2. Conversely, in the drive 1 optical drive, CPU 4 receives the data UDF and VMG at step SP3 in figure 4 to provide the treatment management system to access each advanced file-based data UDF, for playback thereby also file extensions.

On Fig shows a graphical diagram of the operations of recording, described above with reference to figure 4 and 5. When you start the recording process, the CPU 4 proceeds from step SP11 to step SP12, where it determines which command submitted by the user: the file entry of the moving image, the recording of the still image file or completion.

When the user command is in the file record of the moving image, the CPU 4 proceeds from step SP12 to step SP13, where he defines filed if the user command to start recording. If the result of determination at step SP13 is negative, then the CPU 4 repeats the operation of step SP13. If the result of determination is positive, the CPU 4 proceeds to step SP13 to step SP14, where he writes real data, as described above with reference to figure 4. Then, the CPU 4 proceeds to step SP15, where he defines filed whether the user command to stop recording. If the result of determination at the step SP15 is negative, the CPU 4 returns to step SP14. Thus, the CPU 4 repeats steps SP14, SP15 and again step SP14, recording thereby sequentially real data. When the result of determination is positive, the CPU 4 stops recording data VTSTT deviations, VOBs and out of the account the actual data.

Stamp 4 goes to step SP16, where he consistently sets the field VTSI BUP, VTSI and VTSM deviations, VOBs on the optical disk 2, thereby recording one VTS, and then goes to step SP17, where he comes out of this write process.

On the other hand, when the user is recording the still image file, the CPU 4 proceeds from step SP12 to step SP18, where he defines filed if the user command to start recording. If the result of determination at the step SP18 is negative, then the CPU 4 repeats the operation of step SP18. If the result of determination is positive, the CPU 4 proceeds from step to step SP18 SP19, where he writes advanced file for a still image file, as described above with reference to figure 4 and 5. Then, the CPU 4 proceeds to step SP20, where he defines filed whether the user command to stop recording. If the result of determination at step SP20 is negative, the CPU 4 returns to step SP19. Thus, the CPU 4 repeats steps SP19, SP20 and again step SP19, recording thereby sequentially files of still images. If the result of determination is positive, the CPU 4 stops recording of the still image files and moves to step SP21, where he writes the intermediate management information, and proceeds to step SP17, where he comes out of this write process.

When the team of the user who is recording data, related to the completion of the optical disk 2, the CPU 4 proceeds from step SP12 to step SP22, where he defines filed if the user command to start recording. If the result of determination at step SP22 is negative, then the CPU 4 repeats the operation of step SP22. If the result of determination is positive, the CPU 4 proceeds from step to step SP22 SP23, where he completes the optical disk 2, as described above with reference to figure 4 and 5, and then goes to step SP17, where he comes out of this process.

Figure 9 shows a graphical diagram of the operations of the playback process shown in figure 4. When you start the playback process, the CPU 4 proceeds from step SP31 to step SP32, where he defines filed whether the user command for reading the file of the moving image or a still image file.

When the user is playing a moving image, the CPU 4 proceeds from step SP32 to step SP33, where he defines filed if the user command to start playback. If the result of determination is negative, the CPU 4 repeats the operation of step SP33. When the result of determination is positive, the CPU 4 proceeds from step to step SP33 SP34, where it provides a management system for file playback of the moving image specified by the user, cos the ve control information, stored in memory.

That is, when the optical disk 2 is completed by the disk, the CPU 4 detects the address of the desired file on the basis of the VMG data stored in its internal memory, and issues commands to each of the components of the drive 1 optical drive to read the file from the address. On the other hand, when the optical disk 2 is unfinished disk, CPU 4 detects the address of the appropriate file based on the table entry TV control and recording VTSI and VTSTT deviations, VOBs corresponding names stored in the memory, and sends the command in each of the components of the drive 1 optical drive to read a file from a url.

After submitting commands to reproduce the CPU 4 proceeds to step P35, where he defines filed whether the user command to stop playback. If the result of determination at step P35 is negative, the CPU 4 returns to step SP34. Thus, the CPU 4 repeats steps SP34, P35 and again step SP34 for sequential reads of files of moving images specified by the user. On the other hand, when the result of determination is positive, the CPU 4 ends the playback operation and proceeds to step SP36, where it emerges from the process of reproduction.

On the other hand, if the user command to read extended file, the CPU 4 proceeds with this is and SP32 to step SP37, where he defines filed if the user command to start playback. If the result of determination is negative, the CPU 4 repeats the operation of step SP37. Conversely, when the result of determination is positive, the CPU 4 proceeds from step to step SP37 SP38.

In the case where the optical disk 2 is completed by the disk, the CPU 4 detects the address of the specified file based on the data UDF, stored in its memory, and delivers the commands in each of the components of the drive 1 optical drive to read the file from the address. On the other hand, when the optical disk 2 is unfinished disk, CPU 4 detects the address of the corresponding file on the basis of the record management table stored in memory, write the guide information and the corresponding intermediate data management and delivers the commands in each of the components of the drive 1 optical drive to read a file of addresses.

After issuing a command to reproduce the CPU 4 proceeds to step SP39, where he defines filed whether the user command to stop playback. If the result of determination at step SP39 is negative, the CPU 4 returns to step SP38. Thus, the CPU 4 repeats steps SP38, SP39, again step SP38 for sequential reads of files of still images specified by the user. Naoborot, if the result of determination is positive, the CPU 4 ends the playback operation and proceeds to step SP36, where it emerges from the process of reproduction.

Figure 10 shows the graphical scheme of guidance THE advanced file and information CI management. Guide information THOSE intended to control the whole region, which recorded a corresponding extended file, and contains the address specified in the above table control RAM. It should be noted that it is possible to determine if there is any guide information of THOSE using the flag EX_STATUS_FLAG specified in the area occupied by the table TV control, and set the top address and size of it. Guide information consists of THOSE temporary table control information (TMP EXTI MAT) and a table of pointers to information search category (CAT INFO SPRT)recorded consistently.

Specified temporary table control information (TMP EXTI MAT) contains several tables of pointers to information search category (CAT INFO SPRT), located behind the control table. Each of the tables of pointers to information search category (CAT INFO SPRT) manages file extensions using each category.

In accordance with ISO/IEC 646:1983 (a-trait) time table information management (TMP EXTI MAT) contains 12 upper byte code is automatically recognized, specifies that the table is a temporary table of information management. Using the following two bytes are written to the version number of the corresponding table TV control. The following two bytes are reserved, and the number of the table of pointers to information search category (CAT INFO SPRT) is written using a single byte following the reserve two bytes. In this embodiment, the number of tables is in the range from 1 to 256. The next three bytes are the backup.

Thus, the guide information is THE same information that you can find a temporary table of management information (TMP EXTI MAT) table-based TV control to determine the number of tables of pointers to information search category (CAT INFO SPRT), which is included after the table control TMP EXTI MAT.

Table of pointers to information search category (CAT INFO SPRT) is specified for each category of the extended file, as shown in figure 11. In each table of pointers to information search category (CAT INFO SPRT) ID CAT ID specifies the type of the extended file by using the upper two bytes. In the following two bytes specify the type of information CAT INFO TYPE, which is the format of the relevant information CI management and specifies the record format of the individual information EFX. In the next four bytes specify the address and the formation CAT INFO SA, specifies the address of the beginning of the relevant information CI management, and in the following four bytes is the size of the CAT INFO SZ relevant information CI of the control.

In the specified table of pointers to information search category (CAT INFO SPRT) ID CAT ID that specifies the format of the extended file is suitable for still image file. For example, "01" is for a still image file, formatted in accordance with the JPEG format, and "02" is suitable for still image file, formatted in accordance with the graphics interchange format (GIF).

Thus, the recording formats of information CI management and individual information EXF can be confirmed in accordance with the type information CAT INFO TYPE with format detection code-based identification CAT ID using sequentially a table look-up TV control. Therefore, when the newly recorded based on the bitmap file is a still image in the form of an extended code file identification CAT ID specified only as 01 or 02, the format formatted in accordance with format JPEG still image file may be made to the relevant information CI management and individual information EXF due to state changes only identifying code, CAT ID and installation information type CAT INO TYPE, the same type of information formatted in accordance with format JPEG still image file. Thus, in this embodiment, the procedure is added to the formats made writable files can be simplified and is provided with a recording capacity of the optical disk 2.

In addition, due to the specified compliance formats information CI management and individual information EXF, optical disk 2 can be completed for a file, not a given treatment, with intermediate information DK control, similar formatted in JPEG format file, a still image, thereby providing a sufficient expansion of the recording capacity of the optical disk 2.

Thus, information CI management and individual information EXF can be set in accordance with each table of pointers to information search category (CAT INFO SPRT), as shown in Fig. It should be noted that information CI of the control is changed according to the structure depending on the type of information CAT INFO TYPE in the table of pointers to information search category (CAT INFO SPRT). The type of information CAT INFO TYPE can be set in accordance with the category of advanced file pertaining to individual information EXF-driven information CI of the control.

On Fig shows a case in which oterom type information CAT INFO TYPE is 01, the structure of this type 01 is applied to the intermediate data DK of management for the above still image file.

It should be noted that according to ISO/IEC 646:1983 (a-trait), information CI of the control points in their top 12 bytes of the identification code CAT INFO ID indicating that it is the management information for the extended file, the following two bytes specify the version number of the TV VERN information management TPMJVMGI. Information CI are the following two bytes are reserved, and the following eight bytes specify the catalog number on the first hierarchical level advanced file according to ISO/IEC 646:1983 (e-sign). In addition, the following eight bytes specify the catalog number on the second level.

In addition, in the following eight bytes specify the ID for updating the IMP ID, the following 12 bytes indicate the time stamp CR TM indicating the date and time setting information CI management, and the following 12 bytes indicate the timestamp MD TM indicating the date and time of the update, when was the last time you updated information CI management. The next two bytes indicate the number of separate information EXF1-EFXn within the range from 1 to 9999, and the last two bytes are the backup.

On the other hand, as shown in Fig, individual information EXF has its top 12 bytes to specify the name of the file the FILE NAME, and the next byte indicates the information of copyright protection CGSM INFO. The next three bytes of the individual information EXF indicate the start address EFX SA corresponding extended file, the next four bytes indicate the size of the file EXF SZ, and the following 12 bytes are used for timestamps CR TM indicating the date and time when it was generated individual information EFX.

Thus, the actuator 1 of the optical disk is arranged to inform the user about the file extension is recorded on the optical disk 2 through the directory structure by conducting a sequential view of the guide information, THOSE information CI management and individual information EXF for extended file support on the TV table management, and with the possibility of obtaining various information necessary for file management PC from this guide THE information, information CI management and individual information EXF.

As mentioned above, the CPU 4 receives the property, the name, the size, etc. of each advanced file in accordance with the instructions of the above guide information, THOSE information CI management and individual information EXF during the completion process to generate UDF.

Drive 1 optical drive that contains the design described above with reference to Phi is .3, works in the following way.

When the user loads the optical disk 2 in drive 1 optical drive, or when the drive 1 optical drive is enabled after loading the optical disk 2, the CPU 4 controls the processor 14 signals DVD and amplifier 18 for motors for driving the motor 21 of the slide for moving the optical head 19 in the direction of the inner circumference of the optical disk 2. Then from the optical head 19 is projected laser beam on the optical disk 2. The returned light reflected from the optical disc 2, is measured by the optical head 19. The power of reflection, measured by the optical head, is sequentially processed by the analog block 16 on the external interface and the CPU 4. The CPU 4 controls the optical head 19 through the control processor 14 signals DVD and amplifier 18, which provides control of monitoring and controlling the focus of the optical head 19.

In addition, the data recorded on the optical disc 2 is read by processing the measured power of the returned light reflected from the optical disk 2, the processor 14 DVD signals. In the actuator 1 of the optical disk according to this invention, the CPU 4 receives various kinds of information recorded along the inner circumference of the optical disc 2 using the above series of operations and keeps in memory the built-in is authorized in the CPU 4.

In the case where the optical disc 2 is a CD-ROM only for reading formed by stamping and having recesses and convexes, which indicates that the data recorded on the optical disk 2, or when it is completed the drive with only the files of moving images recorded therein, the CPU 4 receives the data VMG recorded along the inner circumference of the optical disk 2, which is management information for a DVD player in the above series of operations. Thus, in the actuator 1 of the optical disk upon receiving the user command to the playback of the optical disk 2 is driven by the motor 21 of the slide in accordance with the VMG data using the processor 14 signals DVD and amplifier 18 for electric motors, for moving the optical head 19 to the address specified by the user name (seek operation), and the execution of control by the tracking and control focusing of the optical head 19 on the basis of the measured returned light measured by the returned light is sequentially processed by the processor 14 signals of DVD, processor 7 title information and the block 6 compression/deployment order to read the video data constituting moving images. In particular, the read signal resulting from the measurement vozvrashenie the light and changing the level in accordance with the chain of pits on the optical disk 2, processed analog block 16 external interface to create a data read, and the read data are decoded, are deinterleaving and error correction using the processor 14 DVD signals. Then, read data after error correction is served in the processor 7 title information, which is extracted from the data header, and the header is reported to the CPU 4. Then read the signal in block 6 compression/deployment and is divided by a multiplexer 10 on the video data and audio data. Video data extracted by the video processor 8 from the compressed condition MPEG and displayed on the monitor 12 or served to the external device via the video/audio encoder 13. On the other hand, audio data expanded by the audio processor 11 and then fed to the monitor 12 to control or served to the external device via the video/audio encoder 13.

However, when the optical disk 2 is not moved by the drive made with the possibility of overwriting, when loading the optical disk 2 in drive 1, or when switching actuator 1 CPU 4 obtains access to the optical disk 2 to extract data of the RMA. In the drive 1 optical drive when the user selects a shooting mode of the moving image, the CPU 4 updates the RMA data contained in its memory (as shown in Fig.6), and sets by completing the field for the UDF and VMG, and also about the Asti for VTSI of the VTS.

When the user submits a write command, the video data and audio data are served sequentially from the block 3 video input unit 5 input audio and video data are compressed by the video processor 8, using MPEG technology, while the audio data is compressed by the audio processor 11. Then compressed thus video data and audio data multiplexed by the multiplexer 10, and then the multiplexed data are added header data using the processor 7 title information. The processor 14 DVD signals provided downstream, to the multiplexed data is added to the error correcting code and they are subjected to interleaving and coding. In accordance with the result of the processing of these data by the analog block 16 external interface sets the intensity of the laser beam emitted from the optical head 19 on the optical disk 2. Thus, the optical disk 2 are sequentially formed pita for recording video data composed of moving images.

In the actuator 1 of the optical disk, when the user submits a command to stop recording, then the CPU 4 stops the series of operations in block 6 compression/deployment, etc. to stop recording the video data, and then writes to an optical disc 2, the management information for the recorded file, moving the images. Namely, in the drive 1 optical drive, CPU 4 generates the management information of the address, file size, date and time etc. data of moving images and sends the management information to the processor 14 signals DVD and writes it on the optical disk 2, so that the management information is recorded for video data, which sets the scope of the VTSI BUP. Then you set by filling the field for VTSI and VTSM deviations, VOBs next VTS, and the optical head 19 receives a command to search existing VTSI and VTSM deviations, VOBs. Similar control information is supplied to the CPU 14 and DVD signals recorded in the optical disk 2 to specify the planned areas VTSI and VTSM deviations, VOBs.

In the drive 1 optical drive video data composed of moving images are recorded for one name. Thus, in the drive 1 optical drive for a file record moving images are recorded, the management information and the file in DVD video format, which are consistently the management information consisting of VTSI, information management, consisting of VTSM deviations, VOBs, file moving images and information management, consisting of VTSI BUP. Then when the user submits a command to record moving images, the actuator 1 of the optical disk repeats similar operations for sequential write names on the optical disk 2.

After the termination of recording of moving images for the same title written upper and lower addresses of the names in the table control in the field of RMA on the inner circumference of the optical disk 2.

When the optical disk having such consistently recorded therein the names and not yet completed, is loaded in drive 1 optical drive, get a table control, consistently get the management information is recorded in combination with the names, by scanning the optical disk 2 in accordance with the management table, and they are stored in the CPU memory 4. Then read the file moving image specified by the user, based on the thus obtained information.

In the drive 1 optical drive when the titles recorded on the optical disk 2 as stated above and the user submits a command to complete the optical disk 2, the data generated UDF and VMG in accordance with the management information is recorded in combination with the names in the memory of the CPU 4 based on table records management, and written in the area of the inner circumference defined in the optical disk 2, and also specified area of the input zone and output. Thus, this optical disk can be set to playback a DVD player that supports only regular DVD format.

On the other hand, if the user selects a recording mode still image in a blank disk reserved area UDF and VMG, as well as when recording moving images. In addition, in the optical disk d is them a means of obtaining image is switched to a still image, and the mode of operation of block 6 compression/deployment switches to the mode for data compression based on JPEG.

When a user submits a command to start recording still images in these conditions, the video data consisting of still images supplied from block 3 input video is compressed by the video processor 8 of the block 6 compression/deployment in JPEG format. Thus, in the actuator 1 of the optical disk are created for recording video data consisting of still images, not video data consisting of any moving images, and sequentially recorded on the optical disk 2 as when recording moving images.

In this drive, 1 optical drive for recording moving images first areas are specified for VTSI and VTSM deviations, VOBs for recording actual data, however, to record still images with real data, consisting of still images, recorded at the top of the areas reserved by filling. Namely, for recording still images there is no need to reserve such areas as VTSI and VTSM deviations, VOBs. In addition, when the user gives a command for recording still images, the still images are sequentially recorded on the optical disk 2 as stated above. When each record is written to the address of each file in the memory of the CPU 4.

the drive 1 optical drive when you stop recording a still image by the user by changing the mode of operation or otherwise after recording on the optical disk by the desired number of files of still images written stored in the memory, the management information comprising addresses, etc. as a temporary staging control information intended for use to complete the disk in sequential areas for a variety of still-image files. Thus, in the actuator 1 of the optical disk to record other files other than the file of the moving image, recorded files and information management for them in the sequence file and the management information and select the format for recording files and information management depending on the sign of the files to be written.

As mentioned above, the actuator 1 of the optical disk can be recorded on the optical disk 2 files of still images, not defined in the DVD video. In addition, when the optical disk 2 that contains recorded so the still-image files, is loaded into the optical disc drive that supports only video format the DVD, then found the management information recorded in accordance with the DVD video, such as VTSI or so, with the help of the search performed during boot disk, and on the basis of the control information is read VTS. Thus, the files of still images and information management for files not affect the reading of any moving images. Therefore, the conventional DVD player can read the file of the moving image from the optical disk 2, contain it recorded in this way the moving image file.

In the drive 1 optical drive collectively laid such intermediate information DK control (as shown in Fig.6) for a large number of files recorded consistently, and provides information CI management, providing full control. After this is written individual information EXF, including the top address of each file and the name of the file, and recorded the top address of the intermediate data DK management in the form of guidance THE advanced file in a fixed region along the inner circumference of the optical disk 2. In addition, table, TV control is recorded address guide information THE extended file.

Thus, the optical disc drive, which supports files other than the files of moving images, can read files of still images. That is, in the actuator 1 of the optical disk loaded with the above optical disk 2, the system first searches in the optical disk 2 based on a table control to read data VTSI and VTSM deviations, VOBs, and the intermediate data DK control for still-image files from the optical disk 2, and the management information held in the memory of the CPU 4.

Thus, the name under which ijnih and still images, recorded in the optical disk 2 according to the user commands available to the user. In addition, when the user gives a command for reading out the moving image, the drive 1 optical drive can read files of moving images based on the data VTS and VTSM deviations, VOBs, as discussed above with respect to the optical disk to read-only.

On the other hand, when the user submits a command to read the still image file, it executes the detection of the address, etc. of a file based on the intermediate data DK management, held in the CPU 4 sequentially reads the stored on the optical disk 2 data in accordance with a result of detection and processed using operations similar to the read operation moving images. In the drive 1 optical drive for processing read data including a still image, the processing of data read operation of the video processor 8 is modified by using the CPU 4 for the deployment of video data compressed in accordance with JPEG, and video data including a still image is controlled on the monitor 12, and then may be filed with the video/audio encoder 13 to the external device.

Typically, the still image file is smaller than the file of the moving image. However, in the drive 1 optical drive temporarily the second management information is generated as information management and written to multiple files. Thus, in the actuator 1 of the optical disk is recorded as advanced file consisting of these files, still images, or the like, it is possible to minimize the reduction of the areas of record by recording control files.

In addition, the intermediate management information for multiple files collectively recorded for each type, which are characteristic of the file, due to which the seek operation and the completion of the detailed description which will be given below) can be simplified.

In particular, since the address of such intermediate information DK management change due account of the different types of files, it is possible that the intermediate management information is recorded for each of the multiple files. The addresses of the intermediate information management can be adapted through the entries for table management, however, in the case of the records in each of the expanded file only with the management table provided for advanced file during the recording of files of moving images, when writing multiple files extensions on the optical disk, the file extension may not be many control tables. However, in this embodiment, as the guide information TE by using the table control and information CI control on the I collective management consistently recorded file extension is controlled by the guide information, THE extended file such irregularity addresses and write multiple files can be adapted at the same time.

In addition, since the address (guide information) THE intermediate data DK of the control is written in such a table control, you can provide quick and easy access to the extension file by logging into the optical disc 2 based on the information THOSE addresses. In addition, through the use of tables TV control for files of moving images, as mentioned above, it can prevent the occupation of a field recording information due to the separate generation of such table for each advanced file and thus more efficient use of the recording area information.

In the drive 1 optical drive such extension files are written each in combination with intermediate information DK1 control file. Thus, if necessary, record any new intermediate information DK management updated existing in the intermediate disk information DK control in combination with the new intermediate management information, as described with reference to Fig.7. In addition, by updating the last intermediate data DK1 control in the above combination is updated or deleted any advanced file. Thus, in the optical drive 1 is on disk even if the set file extension is recorded separately, access to the appropriate advanced file can be provided by obtaining the intermediate data management in one place that also provides fast input of the actuator 1 on the optical disk 2.

With the above operations, the actuator 1 of the optical disk according to the user commands sequentially writes the files moving and still images on the so-called pristine disk, an optical disk having recorded therein only moving images, but not yet completed, and an optical disk having recorded thereon files moving and still images, but not yet completed.

On the other hand, when the user submits a command to complete any of the above optical disc having recorded thereon the moving and still images are generated for computer data UDF-based information management and interim control information received from the optical disk and stored in the CPU memory 4, as well as information management and interim control information that is generated when recording moving and still images stored in memory, and the data recorded in UDF pre-reserved region on the optical disk 2. In addition, data generated VMG for DVD player only in accordance with management information for f the La moving image and the same image is recorded on the optical disk 2.

Thus, in the drive 1 optical drive collectively written to the management information for all recorded on the optical disk 2 files in combination with the files in the UDF field for recording the first information management area for recording management information on the optical disk 2, while the management information for the file of the moving image that has a special characteristic and recorded on the optical disc 2 is recorded in combination with the moving image file in the VMG area intended for the DVD to record the second control information.

Thus, when the optical disk 2, completed as stated above, is reproduced by the DVD player, the files recorded on the optical disk 2 is read based on oriented DVD region VMG, which can be successfully read moving images, formatted in DVD video format, without affecting the records of other files, such as still-image files.

When playback is completed, the optical disk by the computer, as specified UDF format control files corresponding to the file management system of the computer, and the computer reads each file based on the UDF, then you can read the file of the moving image and the still image file.

Thus, in the drive 1 optical drive capable in which to perform recording on the optical disk 2, the still-image files in addition to files of moving images, individual information EXF, which is management information for each of the extended file, grouped in accordance with the information CI of the control, and the upper address information CI of the control is written in the guide information, THE extended file. In the drive 1 optical drive guide information THOSE included the identification code CAT ID that specifies the types of files extensions, collectively managed on the basis of information CI management, as well as information CAT INFO TYPE of recording format for the corresponding individual information EXF, apart from identifying code, CAT ID.

Thus, to write the file generated from GIF, bitmap, or the like, for example, is different from any of the still image file in JPEG format in the optical disk, the user can write such different types of files on the optical disk 2 through the installation of individual information EXF control and recording format CAT INFO TYPE, with the same files, still images, and change only identifying code, CAT ID indicating the type of the extended file. In addition, by generating a UDF by ending the possibility of computer access to the recorded file as stated above. Thus, in this embodiment, it is possible to add other files other than the files of moving images in the optical on the SC 2 with sufficient expand the recording capacity of the disk.

Drive 1 optical drive containing the above design, provides access to the individual information management through the guide information of advanced file and the file still images that are different from the files of moving images on an optical disk with sufficient expand the recording capacity, by location identifying code indicating the type of the corresponding advanced file and record format of the control information in the guide information of the extended file.

In addition, the address of guidance for the extended file, which can be used to identify the address of the control information for file extension is installed in the area of the inner circumference of the optical disk, where the first recorded file, which can also be written guide information in a fixed region. Thus, access is provided to the guide information of the extended file regardless of the management table, to identify the address information management, which leads to efficient use of the recording area of the information and thus to a rapid search in the recording area in the optical disk.

For recording control information for the additionally recordable extended file collectively zapisywa the tsya information management for existing files extensions and guide information for file extension is updated in accordance with the recording of additional advanced file and the corresponding control information. Thus, when reading a piece of information management can identify the addresses of all the extension files recorded on the optical disk, and in accordance with this excludes frequent access to the optical disk 2.

By reading files containing the relevant characteristics recorded on the optical disk on the basis of the recorded information management, non-moving images, you can read and use files other than the files of moving images.

In addition, due to the collective account information management in combination with all the files recorded in the optical disc, the first recording area of information management and information management in combination only with files that have a specific characteristic, a second area for recording control information can be read from a file of moving images using some ordinary DVD players and all the files moving and still images using some computers.
