Prior art

In recent years witnessed significant improvements in the methods of optical recording (i.e. methods for recording data to optical disks). During the implementation of these improvements have been developed various types of devices for playback/recording on optical discs.

Optical discs are write-once type optical disc, on which data can be written only once. For example, conventional recordable compact discs (CD-R) and recordable digital versatile discs (DVD-R) are the types of optical disks, write-once. Typically, in optical disks, write-once the state of the recording layer is changed by application of heat to the pre-specified area of the recording layer using a laser beam to form a record label.

Defect management includes overwriting user data, which were recorded in the user data area, where there was a defect, so whom is insinua loss of data, otherwise, caused by occurrence of the defect. Traditionally, the management of defects classified into defect management using the method of linear replacement defect management using the replacement method through passes. In the method of linear replacement area in the user data area, where it formed the defect substitute area of the back area where the defect does not appear. The replacement method passes through the region where the formed defect, pass without the use of an area and use the next region where the defect is not formed.

In the case of way line replacement unit from the data area of the user, where the defect is formed, is called a defective block, and a reserved area which is an area for the location of a replacement block to replace the defective block is provided in a predetermined area of the disk.

Since optical disks, write-once cannot be overwritten, can be adopted ways of managing defects, different from the methods used in rewritable (multiple record) disks. In the case of optical disks, write-once the above ways of managing defects may or may not be used.

The best mode of carrying out the invention

Below is a detailed description with references to existing embodiments of the present invention, examples of which are illustrated in the accompanying drawings, in which similar digital reference designations refer to like elements. Options for implementation are described below to explain the present invention with reference to the drawings.

Figure 1 is a state diagram of the recording medium write-once according to the aspect of the present invention and shows the life cycle of the recording medium write-once during the period from initialization to complete processing (finalizing) according to the DM mode is on (enabled management defects (UD-on)) or DM mode-off (off management defects (UD-off)). The recording medium write-once according to the aspect of the present invention can be used in two modes according to whether the management defects or not. The first regime is the DM-on, in which the data recorded on the recording media while you manage defects on the recording medium. The second regime is the DM-off mode, in which Dan is haunted recorded on the recording medium, while not performed defect management.

In the DM-on mode, the backup area is assigned in the data area provided in the recording medium, and data recording control device (drive) on the recording media while you manage defects in the presence of the intentions of the user or the manufacturer of the drive. In the DM-off mode, the data recording control device (drive) on the recording medium without defect management, in which recording is performed in the presence of the intentions of the user or the manufacturer of the drive. As the reserve area assigned to a part of the field data is provided for managing defects, and since the defect management is performed on the DM-off mode, it is natural that the backup area cannot be assigned in the DM-off mode. While figure 1 is illustrated without reinitialization of the DM-off mode in the DM-on mode, it is understood that such a re-initialization of the DM-off mode in the DM-on mode is possible up to the point where DMA (OAD) is not filled until the processing is completed.

DM-on mode

The life-cycle optical media write-once according to the DM-on mode is shown in the upper part of figure 1. In the following description, the terms "drive" and "recording media" are used interchangeably and are not limited to specific media type (media). When the disk is made and what drives by, used for the first time, the disk is a blank disk 1, on which no data is recorded. However, the empty disc 1 includes the initial track, the data area and the target area that are assigned (allocated) during manufacturing of the disk. The structure of an empty disk 1 shown in figure 2 and 3. The reserve area shown on figure 2 and 3, is not assigned during manufacture of the disk, but is assigned during initialization of the disk. The purpose of the backup area depends on whether the management of defects on the disk 1 or not. Thus, the backup area is represented using dashed lines.

If it is determined that a blank disk 1 should be used according to the DM-on mode, a blank disk 1 initialize the DM-on mode. For defect management reserved area prescribed in the field empty data disk 1, and the initialization information for defect management recording in a predetermined area of the blank disk 1. The purpose of the reserve areas is described below with reference to figure 2 and 3.

Figure 2 illustrates the data structure schema of the disk 1 in the form of a version of the recording media with a single layer for recording according to the aspect of the invention. With reference to figure 2, the initial track, the data area and the target area are provided sequentially in a single record layer. The initial track, the area data is x and the target area are assigned during manufacturing of the disk. If you are managing defects through the device drive (drive) is relative to the disk 1 during initialization to use the disk 1, the backup area is prescribed in the data area. With reference to figure 2, two reserve areas assigned in the data area and the data area includes a reserved area # 1, the user data area, and a reserved area # 2. Data recording starts at a location having a logical sector number (LNS, LSN) 0 from the data area of the user and going to the location with the last LSN. Although not required in all aspects, a reserved area # 2 is used after the backup area # 1 is fully recorded (i.e. filled). In the backup area # 2, if the entry occurs in the direction from the target area to the data area of the user can be made easily change the size of the backup area # 2 in the form of expansion or contraction.

Figure 3 is a diagram of a data structure of the disk 1 version of the recording medium with two recording layers according to the aspect of the present invention. The structure of the recording medium with two recording layers is similar to the carrier 1 record with a single record layer, shown in figure 2. One layer of the device 1 records with two layers of recording includes the initial path # 0, the data area # 0, and terminal C is well # 0 consistently. Another layer includes the initial path # 1, the data area # 1 and the target area # 1 consistently. Determined that managing defects through the drive device must be performed during initialization of the disk. Thus, the backup area # 1 and # 2 are designated data area # 0, and the backup area # 3 and # 4 are designated data area # 1. In other words, the data area # 0 includes a reserved area # 1, the user data area # 0, and a reserved area # 2, and the data area # 1 includes a reserved area # 3, the data area of the user # 1 and the backup area # 4. To facilitate the extension of the backup area # 4, it is desirable, but not required, to use the disk 1 so that the LSN increases in a direction from the field # 0 user data area # 1 user data, as shown in figure 4.

Detailed structure of the initial track and the target zone of the recording medium 1 shown in figure 2 and 3, described below with reference to figure 4. Figure 4 is a detailed structure diagram of the data fields of the medium 1 recording write-once according to the aspect of the present invention. With reference to figure 4, as described above, the holder 1 of the write-once recording includes the initial track, the data area and the target area, consistently placed, and the reserve areas # 1 and # 2 designate is in the field of data during disk initialization for defect management. Primary track includes scope management defects (OAD, DMA) # 1, region information of the disk drive, staging area management defects (intermediate state control, TDMA), the scan area of the recording conditions, and a DMA # 2. The target area includes a DMA # 3 and DMA # 4. Naturally, a detailed area assigned to the initial track, can also be assigned to a target area in addition to or instead of the original tracks.

The reserve areas # 1 and # 2 are provided to overwrite the data in the replacement block that replaces a block of the user data area when the defect is formed in the data recorded in the data area of the user. Information area of the disc drive is provided for recording information concerning the floppy disk device that loads the disk and writes data to or reads data from the disk 1. The test area of the recording conditions is provided in order to allow the drive device to execute a predefined validation to find the optimal conditions for recording/playback of data in the loaded disk.

DMA is provided for recording information on the defect information and defect management (JUDE, DMI). DMA includes structure defining a drive (ODS, DDS) for DMI and the list of defects (DM, DFL) for information about defects and is provided for compatibility with rewritable media write or read is occurring and record the final information about defects and DMI, recorded in the TDMA during the complete processing of the disk.

TDMA is recorded while the updated time information of the defect management. The time information of the defect management includes temporary structure definition disk bitmap space (zone) (BMP, SBM), which specifies the entry or non-entry into the physical blocks of disk space available, using bit values, and the temporary list of defects (IRR, TDFL) for temporal information about the defects. In other words, TDMA is provided for recording temporal information management defects (VID, TDMI), including a temporary structure definition disc (SOD, TDDS), SBM and TDFL.

TDMA trained to manage defects through the floppy disk device on the recording medium write-once. In particular, in the rewritable recording media is provided only DMA, TDMA additionally is provided. This is because the recording medium with a single entry cannot be overwritten, as can be done for rewritable media. Unlike rewritable recording media as the recording media with a single entry cannot be overwritten when the DMI should be updated, need a new scope, which should be recorded for updated information. So about what atom, requires a relatively large number of regions in proportion to the number of times of update DMI. However, since DMA is not large in the rewritable recording media, TDMA is provided on the recording medium write-once, and DMI is updated in the TDMA. Also during the complete processing of the disk finally updated TDMI in TDMA (i.e. TDMI from the last write operation is recorded in the DMA as DMI. Recording DMA DMI provided on the recording medium write-once, can be achieved compatibility with rewritable media accounts. For convenience of explanation DMI, updated in the TDMA, named as "TDMI", and the final TDMI recorded in the DMA, named as "DMI".

Described in detail below TDMI recorded in the TDMA. TDMI includes a TDDS, SBM and TDFL. When TDDS, SBM and TDFL is recorded in the TDMA, the TDDS and SBM can be written in the same block, and TDFL can be written in another block. For example, as shown in figure 5, TDMI includes TDMI # 0, composed of TDFL # 0, TDDS # 0 and SBM # 0 and can be updated in blocks TDMI # i in TDMA. As another example, as shown in Fig.6, TDMA is divided into two parts, TDDS # i and SBM # i can be updated as a single unit in one part, and TDFL # i can be updated as one block in the other part. Detailed structure of the TDDS # i is described below with reference to Fig.7.

7 illustrates in detail the data structure schema TDDS # i in TDMI with the public aspect of the present invention. With reference to Fig.7, TDDS # i includes information initial location data of the user, information from the latest location data of the user, information on the size of the backup area # 1, information on the size of the backup area # 2, TDFL pointer, pointer available location of the test recording conditions, the check processing is completed and the DM mode.

The location and size of the user data assigned to the data area, and location of the backup areas # 1 and # 2 can be obtained from the information of the initial location data of the user and information of the last position of the data area of the user. The location of the backup size field # 1 and information of the size of the backup area # 2 is written as TDDS, and information about the size of the backup area # 1 or # 2 is changed, if the backup area # 1 or # 2 is expanded or reduced. The TDFL pointer indicates the location information recently updated TDFL. Using the TDFL pointer, finally updated TDFL can be easily found.

Index available locations check the recording condition specifies the location information verification recording conditions provided in the initial track or target area of the disk, which can be verified. Referring to the pointer to the accessible location of the test recording conditions, can be found easily the location where the inspection can be performed without going through the verification of the recording conditions.

The box is complete check box to install the complete processing of the disk, and it is possible to determine, using the check processing is completed, complete the processing of the disk or not. Although the box is completed is provided in the TDDS # i 7, the box is complete, you can ensure SBM # i, as shown in Fig.

DM mode figure 7 indicates whether defect management on the corresponding disk 1 or not. For example, when data is recorded on the disc while defect management is performed on the disk 1, the DM mode is set in the DM-on mode, and when the data recorded on the disc 1 while defect management is not performed, the DM mode is set in the DM-off mode.

Fig depicts a detailed diagram of the data structure SBM # i of the temporary management information disk according to the aspect of the present invention. With links to pig, SBM # i includes the SBM header and bitmap. SBM header is an identifier indicating SBM. The bit array is an information card, which specifies the entry or lack of entry into the block physically recordable area of the disk, using the bit values. For example, the block where the data is recorded, represented by "1" and the block where the data is not recording the HN - represented by "0". Thus, it is possible to know whether an entry or no entry in each block.

Fig.9 depicts a detailed diagram of the data structure TDFL # i of the temporary management information disk according to the aspect of the present invention. With reference to Fig.9, TDFL # i includes a TDFL header, entry # 0 of the list of defects, entry # 1 list of defects .... the TDFL Header is an identifier that specifies the TDFL. Entry # i list of defects specifies information about the defects formed in the data area of the user. Figure 10 shows the structure of data record # i list of defects shown in Fig.9.

With reference to figure 10, entry # i list of defects includes status information, the physical address of the defective block, and a physical address of a replacement block. The physical address of the defective block specifies the physical address of the defective block in the user data area, and a physical address of a replacement block specifies the physical address of a replacement block of the backup area, which replace this defective unit. The status information indicates whether replacement information and subsequent information about the defects. Replacement information indicates whether a defective block replacement block. In other words, there is a state of the defective block with a replacement block, and the condition of the defective unit, without n is a replacement unit. "Further information about defects indicates the status of the defective block when the defect is formed in the user data area is formed in the subsequent blocks. In other words, when the defect is formed in sequential blocks in the data area of the user account list of defects for each of the subsequent blocks are not done, but is done only the first record of the defect of the first defective block among subsequent blocks and the last record of the last defect of the defective block among the subsequent blocks. Thus, it is possible to save space TDFL.

The following describes an exemplary structure of a recording medium, with respect to whom may be applied the present invention. With reference to figure 1, after the initialization of the DM-on mode blank disk 1, the DMA disk is empty, and TDMA is in state 2, where TDMA can be updated. Update TDMA indicates that TDMI updated in the TDMA. The upgrade is performed in units (stages) preset write operations, which may be the same module (single operation) "verify-after-write" or many modules (multiple operations) to "verify-after-write", by means of which the block is recorded and then verified or removed according to the aspect of the invention. Here "block" means a module for error correction code (ECC)recorded on the disc. However, animalsa, what can be used other ways to update and/or made otherwise than in units of write operations.

The data recorded on the disk 1 in state 2, when managing defects through the floppy disk device runs on disk.

Then, TDMA, as shown in figure 4, supports state 3, where TDMI is updated according to the write data, simultaneously with the control defects. When using disk 1 in state 3, if any change occurs in the backup area of the disk 1 re-initialize, information on the size of the backup area TDMI change, the changed information on the size of the backup area recorded in the TDMA and DMA is still blank. If the reserved area is assigned during initialization of the drive is fully used, and the reserve area should be expanded, or if the data area of the user lacks the area where the data should be recorded, and the reserve area must be reduced, information on the size of the backup area change during use of the disk 1 (state 4). TDDS # i, which includes such changes, recorded in the TDMA. Even after the size of the backup area is changed, data is written to disk 1, at the same time performing the defect management device of the drive in relation to the disk, and TDMA update (state 5).

The disc 1 may be the initialized setting different for DM-off mode during recording data simultaneously with the control defects. When the disk 1 re-initialize the DM-off mode for compatibility with rewritable media account that the final TDDS and information TDFL recorded in the TDMA is recorded as information DDS and DFL in DMA, TDMA changes to the DM-off mode. In other words, is updated in the TDDS, shown in Fig.7, by setting DM mode in the DM-off mode and finally updated TDDS # n and TDFL # n in TDMA is copied and recorded in the DMA (11-13).

In particular, after the re-initialization for the DM-off mode, the DMA disk 1 is filled, and TDMA is included in the state 11, where TDMA can be updated. As DM mode is changed in the DM-off mode, data is written without defect management, and TDMA is updated (status 12). As defect management is not performed, the update TDMI is mainly concerned with TDDS # i and SBM # i. However, if the content (content), not associated with managing defects included in the TDFL # i, TDFL # i can also be updated. While the disk 1 is used so that if the processing of the disk 1 is completed, TDMA must be completed and included in the state 13 where the box is complete and installed in a TDMA (state 13).

While data is written to disk in condition 5 and defect management device drive is relative to the disk 1, if the processing of the disk is completed, the flag end is set in TDMA, to prevent the disk from the use of the Oia after processing is completed, and finally updated TDMI in TDMA (i.e. TDDS # m and TDFL # m fill DMA and serve as the final DMI) (state 6). In relation to option implementation, shown in Fig.7, the box is completed is set to "1"to indicate completion of the processing in the TDDS, and TDDS is recorded in the TDMA, to indicate that processing of the disk is completed. Also, to prevent TDMI from the pack in TDMA, predetermined bits (e.g., "FFh"), can fill the remaining area of the TDMA, where data is not recorded. In the TDMA is filled.

DM-off mode

The life cycle of the optical medium write-once according to the DM-off mode is shown in the lower part of figure 1. If it is determined that the disk 1 is to be used according to the DM-off mode, a blank disk 1 initialize the DM-off mode. DMA disk initialized for the DM-off mode, empty, and TDMA is in state 7, where TDMA can be updated. TDDS recorded as initial information in the TDMA during initialization of the disc, includes information initial location data of the user and information from the latest location data of the user, and information about the size of the backup area # 1 and information about the size of the backup area # 2 is written as "0". Also DM mode is set in the DM-off mode.

As defect management is not performed during data write, TDDS and SBM mainly update Aut in TDMA. As defect management is not performed, detailed TDDS data used in the DM-off mode, can be different. To distinguish between TDDS and SBM used in the DM-off mode, used in the DM-on mode TDDS and SBM used in the DM-off mode, called the management information record.

In the DM-off mode, the data recorded on the disk 1 without defect management through the floppy disk device and TDMA supports state 8, when the TDMA can be updated. When the processing of the disk 1 is completed, the flag end is set in TDMA, to prevent the disk 1 from the user after processing is completed (state 9). Also, the final TDMI (i.e. information management record), updated in the TDMA, DMA fills and serves as the final DMI (state 9). A finalized disc 1 is the state in which the check processing is completed indicating the completion of processing is installed in the TDDS or SBM recorded in the TDMA, and the TDDS and SBM, which is permanently updated in the TDMA recorded as DMI in DMA, and values, is equivalent to "FFh", recorded in the remaining area, where SBM can be recorded (i.e. the remaining area of the TDMA), in order to prevent data from records in the remaining region of TDMA.

The recorder/playback, which makes it possible to use the above-described disk is described below with reference to 11. 11 is a schematic diagram of the mouth of the STS recording/reproduction according to the present invention. With links to 11 recorder/playback includes module 21 of the read/write module 23 controls. Module 21 of the read/write head includes a write head the read/write data on the disk 22, which is an optical recording medium according to the aspect of the present invention and/or reading the data recorded on the disk 22. Module 23 of the control module 21 of the read/write head to write data on and read data from the disk 22 according to the aspect of a predetermined file system. In particular, according to the present invention, the module 23 control determines whether to perform defect management during data entry, when a blank disc 22 is loaded in the module 21 recording/playback, and initializes the disk 22 according to the result of determination. The module 23 of the control module 21 controls the recording/playback to re-encode the data on the disc 22 according to the result of the determination, as described in more detail below.

Module 23 includes an interface 24 with the main computer, DSP (digital signal processor, DSP) 25, RF amplifier 26, zeroblock 27 and the system controller 28. During recording, the data interface 24 with the main computer receives the predefined write command from the host computer 29 and transmits the predefined write command on the system exclusive controller 28. The system controller 28 controls the DSP 25 and servoloop 27 to perform the predefined write command received from the interface 24 to the main computer. DSP 25 adds additional data, such as bits of parity, the data received from the interface 24 to the main computer, error correction, creates blocks of error correction (i.e., the ECC blocks), performing coding code with error correction (ECC) with respect to the data, and modulates the ECC blocks in predetermined ways. RF amplifier 26 converts the output data signal from the DSP 25 in RF signals. Module 21 recording/playback includes/write head for reading records from the RF signals transmitted from the RF amplifier 26, the disk 22. The servo unit 27 receives the command required to perform servo control from the system controller 28, and performs the servo control of the head of the read/write module 21 recording/playback.

In particular, according to the aspect of the present invention, the system controller 28 determines whether to use the disk 22 in the DM-on mode or the DM-off mode. This definition indicates whether defect management is to be performed, while data is written to the disk 22. Although not required in all aspects of the invention, the system controller 28 detects input from the user or detects input from from the otolithes drive and uses the detected input data to determine if the disk 22 in the DM-on mode or the DM-off mode. However, it is understood that the input data can be accepted otherwise.

If the system controller 28 determines to use the disk 22 in the DM-on mode, the controller 28 controls the module 21 recording/playback to perform defect management, while data is written to the disk 22. In other words, the system controller 28 controls the module 21 recording/playback to record a replacement block that replaces a defective block of the user data area of the recording medium, where it formed a defect in the backup area of the recording medium 22 through a predetermined operating modules and update information about defects and TDMI for managing defects in TDMA the recording media through a predetermined operating modules. The system controller 28 changes the size of the backup area, while the disk 22 is used in the DM-on mode, as needed. The system controller 28 controls the module 21 recording/playback to record information on the changed size of the backup area (if any) in the TDMA.

Even if the disk 22 is installed in the DM-on mode during initialization of the disc, the system controller 28 can convert DM mode of the disk 22 in the DM-off mode while the disk 22 is used in the DM-on mode. For this conversion of systems the second controller 28 reinitializes the disk 22 for the DM-off mode and controls the module 21 recording/playback to record data on the disk 22 without defect management. In other words, during the re-initialization, the system controller 28 controls the module 21 of the read/write head for recording information indicating that the disk 22 is used in the DM-off mode, TDMA and record TDMI, finally updated in the TDMA, DMA provided on the recording media 22.

When the processing of the disk 22 used thus completed, the system controller 28 controls the module 21 recording/playback to record the check processing is completed, indicating that processing of the recording medium 22 is completed, TDMA, for recording TDMI, finally updated in the TDMA management disk (DMA)provided on the recording medium 22, as DMI, and fill in the pre-defined data remaining area TDMA, which had no record.

When the system controller 28 determines to use the disk 22 in the DM-off mode, it will control module 21 recording/playback to record data on the disk 22 without defect management. In other words, the system controller 28 controls the module 21 recording/playback to record data in the user data area provided on the disk 22 by predetermined operating modules and updates the management information record according to such a record in the temporary management defects, provided on the disk 22. Also in the same manner as in the DM-on mode, when printing handling the AC drive 22 is completed, the system controller 28 controls the module 21 of the read/write head to write the check processing is completed, which indicates that processing of the disk 22 is completed, TDMA, write, TDMI, finally updated in the TDMA, management disk provided on the disk 22, and fill the predetermined data in the remaining area of TDMA, which had no record.

During playback, the interface 24 to the main computer receives the command playback from the host computer 29. The system controller 28 performs initialization necessary to play. Module 21 recording/playback projecting laser beams on the disk 22, and outputs the received light signal after receiving laser beams reflected from the disk 22. RF amplifier 26 converts the light output from the module 21 read/write in the RF signal, and outputs the modulated data obtained from the RF signal in the DSP 25, and provides zerosignal to management, derived from the RF signal, zeroblock 27. Servolock 27 takes zerosignal from the RF amplifier 26 and a command required for servo control from the system controller 28, and performs the servo control of the head read/write. The interface 24 to the main computer transmits data received from the DSP 25, on the host computer 29.

In particular, according to the aspect of the present invention, the system controller 28 oprevselmodule 21 recording/playback for reading information about the mode of TDMA, secured to the disk 22, and reads the data recorded in the data area, based on the read information. When information about the reading mode is the DM-on mode, the system controller 28 controls the module 21 recording/playback to read the finally updated information relating to the defect information and defect management of TDMA, and if the check processing is completed, which indicates that processing of the recording medium 22 is completed, is read from the TDMA, the system controller 28 controls the module 21 recording/playback to read the finally updated information relating to the defect information and defect management of the DMA provided on the disk 22.

When the information reading mode is the DM-off mode, the system controller 28 controls the module 21 recording/playback to read the final information management account in the TDMA. If the check processing is completed, which indicates that processing of the recording medium 22 is completed, is read from the TDMA, the system controller 28 controls the module 21 recording/playback to finally read the updated management information entry of the DMA provided on the disk 22.

Figa-12E depict the sequence of operations illustrating a method of use of the recording media with a single entry in the DM-on mode and the DM-off mode, according to the aspect of the present invention.

Although not required in all aspects, a method for figa-12E may be implemented as software which is read by the computer. Further, it is understood that, if the controller 28 is a General computer or a special purpose, a way to figa-12E may be carried out by a controller 28 that reads the machine-readable medium to retrieve the method encoded on machine-readable media. As soon as the carrier 22 recording write-once loaded into the system with the drive system controller 28 of the system with the drive identifies the downloaded ROM 22 (i.e. the kind of the loaded disk 22), whether the loaded disk 22 recorded, and whether the downloaded ROM 22 is used, using the information stored in the loaded disk 22. If the loaded recording medium write-once identified as a blank disc 22 at step 10, the system controller 28 performs the initialization process according to the command of the user or the intention of the manufacturer of the drive.

At step 15, the system controller 28 determines whether to implement DM mode according to the user's intention or the manufacturer of the drive. When the system controller 28 determines not to perform defect management according to the user's intention or will make the La drive, and selects the DM-off mode, the initialization information recorded on the disk 22 on the stage 20, and the process proceeds to the steps shown fige. As defect management is not performed on the DM-off mode, and the backup area is not assigned, the information about the size of the backup area is recorded as "0" in the TDDS recorded in the TDMA, and the DM mode is set in the DM-off mode.

When the system controller 28 selects the DM-on mode, it assigns a reserved area of the data area of the disk 22, and writes the information required for defect management device drive and the initialization information on the disk (step 30). More specifically, the initialization is included in the TDDS # 0, SBM # 0 and TDFL # 0, and then is recorded in the TDMA. In relation to option implementation, shown in Fig.7, TDDS # 0 includes information about the size and location of the backup area provided in the data area, the information of the starting location and the information of the last position in the data area of the user, the TDFL pointer and DM mode set in the DM-on mode. As soon as the disk 22 is initialized, the DMA disk 22 is empty, and TDMA is included in the state where TDMA can be updated.

After initialization module 21 recording/playback module 23 controls write through "check-after-write" for managing defects in response to a write command from the main com is lutera (operation 40). Following the procedure "to verify-after-write" stage 40 is described in more detail with reference to figv. At step 41, the user data recorded in the data area of the user modules (by stages) so that the procedure "to verify-after-write". At step 42 the recorded data is checked to find the part where the defect is formed, and record a replacement block that replaces a defective block in the backup area. In operation 43, the information regarding defect is created and stored in memory. At operation 44 is determined whether completed predefined write operation. If the predefined write operation is not completed, the process goes to step 41, and the recording is repeated. If the predefined write operation is completed, the process goes to step 50 shown in figa and more on figs.

At operation 50 information on the defect information and defect management update by operating modules. The upgrade procedure on the stage 50 is described in more detail below with reference to figs. When performing operations 51 reads the information on the defects stored in the memory. At operation 52 create a list of defects, including the information about the defects. In operation 53, the list of defects is recorded as TDFL # i in TDMA, g the f i corresponds to the number of write operations. At operation 54 TDDS # i and SBM # i recorded in the TDMA. Detailed examples of such operations 40 for performing recording by means of the procedure "to verify-after-write and operations 50 updates the information on the defect information and defect management are described below with reference to Fig.

Fig is a diagram for explaining the process of defect management according to the aspect of the present invention. Here, the data processing unit can be divided into sector and cluster. The sector is the minimum unit of data that can be managed by the file system or application program. A cluster is the minimum unit of data that can be physically written to disk at a time. Usually at least one sector is one cluster.

The sector contains the physical sector and a logical sector. Physical sector is the space of the drive where the recorded data corresponding to one sector. The address used to locate a physical sector, is called a physical sector number (PNS). Logical sector - block sector, used to manage data in the file system or application program. Similarly, the logical sector number (LSN) is assigned to the logical sector. The recorder and/or playback of data, such as the one shown at 11, which records data on and scity the AET data from disk, finds the location of the data to be recorded or reproduced on the disk using LNS, while the computer or an application program for recording or reproducing data manage all data in units of logical sectors and find the location of the data, using the LSN. The relationship between LSN and PNS is converted, using the fact whether the defect is formed, and the location where the data record.

On Fig depicts a user data area and a reserved area. In the user data area and the backup area has many physical sectors (not shown), which is sequentially assigned to PNS. LSN is assigned at least one block to the physical sector. However, LSN appoint a replacement areas of the reserve areas, except for defective areas in the data area of the user, where the formed defects. As a result, although the physical sector and a logical sector of the same size, if the defect region was formed, PSN and LSN will be different.

User data recorded in the data area of the user in accordance with a sequential recording mode or a random recording mode. The sequential write mode, user data is recorded sequentially and continuously. When the random write mode, user data is not compulsory is on record continuously, and write at random. Refer (1)to(7) indicate the area of blocks that execute procedure "to verify-after-write". The recorder and/or playback of the data records of the user data area (1) blocks, then the recorder and/or playback of data is returned to the beginning of the region (1) blocks and checks recorded whether the user data is normal or formed defect. If the found cluster, which formed the defect, this cluster is identified as a defective cluster and is designated as the defective area (i.e. the defect # 1). Also the recorder and/or playback data overwrites the user data recorded in the defect # 1, in the backup area. A portion of the reserve area, where overwrite user data, is designated as "replacement # 1". Then, after the recording of the user data area (2) blocks, the recording and/or playback of data is returned to the beginning of the region (2) blocks and checks recorded whether the user data is normal or formed defect. If found at least one cluster, which was formed defect, such a cluster is designated as defect # 2. In the same manner as mentioned above, designate a replacement # 2 corresponding to the defect # 2. Also in the field (3) block indicate the defective region (i.e. defect # 3) and replace # 3, sootvetstvuushuu the defect # 3. In region (4) blocks the part where he formed the defect is not found and there is no defect region.

After recording and checking completed in the field (4) blocks if the pending completion of the recording operation # 1 (for example, if the user presses the eject button, or finished recording user data intended for operation # 1 recording), the recording and/or playback of data writes to a temporary information TDFL about defects (i.e. TDFL # 1) location information of defects # 1-# 3, which was formed in the areas of (1)to(4) blocks. Also, the management information for managing TDFL # 1 written as TDDS # 1 in TDMA.

As soon as the operation begins # 1 write data is written in (5)-(7) in the same way as in the areas of (1)to(4) blocks. Thus, denote defects # 4 and # 5 and the corresponding replacement # 4 and # 5. Defects # 1, # 2, # 3, and # 4 are single defective blocks, each of which includes a defect. Defect # 5 is consistent defective block, where subsequent blocks include defects. Replacement # 5 is consistent replacement block that replaces the defect # 5. The block is a physical or logical unit of account and is subject to change. If the pending operation completes # 1 record, the recording device records the temporal information regarding defects #2 (i.e. TDFL # 2), which includes information regarding defects # 4 and # 5, and additionally writes the information recorded in the temporary information regarding defects # 1, accumulating a way. Similarly, information management and fault management TDFL # 2 written as TDDS # 2 TDMA.

Addressing figa, the system controller 28 determines if you want to change the size of the backup area when performing an operation 60, when the backup area is insufficient and should be expanded, or the user data area is insufficient and the reserve area should be reduced. If the system controller 28 determines to change the size of the backup area, information reinitialization is written to the disk 22 at operation 70, and the process goes to step 40. In other words, the modified information on the size of the backup area is included in the TDDS, and TDDS recorded in the TDMA.

Then the system controller 28 determines whether to re-initialize the disk 22 for the DM-off mode (operation 80). If the system controller 28 determines to re-initialize the disk 22, the information reinitialization is written to the disk 22 during operation 81, and the process proceeds to the steps shown fige. If the disk 22 is re-initialized for the DM-off mode, the DM-on mode set in TDDS transform in the DM-off mode to the determination of TDDS and TDDS, and TDFL, finally updated in the TDMA, write to DMA for compatibility with rewritable media.

Then the system controller 28 determines whether to end the processing of the disk 22 (operation 90). If the system controller 28 determines not to terminate the processing of the disk 22, the process continues to step 40, and recording is performed through a procedure to verify-after-write". If the system controller 28 determines to terminate the processing of the disk, the system controller 28 writes to disk the information processing is completed (operation 100).

The record information is completed on the disk operation 100 is described below in detail with reference to fig.12D. The system controller 28 sets the check processing is completed in the "1" in the TDDS or SBM on the stage 101, and writes a specific value in the rest of the region SBM, which had no record at operation 102. According to the shown options for implementation specific values can be recorded throughout the remaining area of TDMA, which had no record. At operation 103 finally updated TDDS and TDFL recorded in the TDMA, filling DMA.

The following describes the operation when the selected DM-off mode, with links to file. At operation 110, the system controller 28 controls the module 21 recording/playback to record data on the disk 22 without defect management. When performing the operation of system 120 to ntroller 28 updates TDMA. As defect management is not performed, in TDMA primarily related to the TDDS and SBM. At operation 130, the system controller 28 determines whether to end the processing of the disk 22.

If the system controller 28 determines to terminate the processing of the disk 22, the information completed is recorded in the DMA (operation 140). The data recording is completed at operation 140 is the same as described above with reference to fig.12D, and will not be re-described. If the system controller 28 determines not to terminate the processing of the disk 22, the process proceeds to step 110, and performs recording without defect management.

As described above, according to aspects of the present invention, the recording medium may selectively be used while running or not running managing defects on a recording medium according to the choice. It is also possible to use a recording medium without defect management even after using the recording media, while defect management is performed on the recording medium. Additionally, the recording media may be used consistent with rewritable media (media). In addition, the recording medium may be a CD-R, DVD-R, Blu-ray discs, Advanced Optical disc (AOD), rewritable storage media, magnetic storage media and/or magneto-optical media, which carry Aut managing defects.

The method of recording/playback can be implemented in the form of machine-readable codes in a computer-readable recording media. Machine-readable storage media include all kinds of recording devices in which stored data that can be read by a computer system. Such machine-readable media (media) entries are ROM, RAM, CD-ROM, magnetic tape, floppy disk and optical storage device, and transmission over the Internet (for example, the carrier signal). Read by a computer, the recording media may be distributed in a computer system connected to a network, and can be stored and used in the form of machine-readable codes. Functional programs, codes and code segments for implementing the method of recording/playback can be easily created with the appropriate skills programmers.
