The invention relates to a method of recording information on a recording medium recordable type by writing marks in a track.

The invention also relates to the recording medium and the recording device the recording media.

The recording method of optical recording media are known from WO 00/43996. The recording medium contains a reference groove, commonly referred to as groove preliminary marking, to indicate the position of tracks in which information is to be in a predictable way by recording optically readable labels. Groove preliminary layout meanders through periodic deviations of the track in the direction perpendicular to the longitudinal scanning (hereinafter referred to as lobularia). Lobularia may be changing period in accordance with additional information, such as address. A recording device is provided with a cylinder for generating a radiation beam for scanning the track. Marks are recorded during the scanning by changing the reflectivity of the scanned surface. Changes in the intensity of the reflected radiation recorded by the system of the main detector. In addition, the scanning device has an auxiliary detectors for generating zerosignal tracking on the basis of grooves preliminary layout for discovery about transtorno deviation of the head relative to the track. Zerosignal tracking are used to control actuators, positioning the head on the track. Change the length of lobularia register to extract auxiliary information, such as address information. If you need to read the recording medium recordable type in the reader, the reader can expect a fully recorded disc, in particular recorded a second record layer and the output area present at the end of the recorded data. The problem is known of the recording media is that when a substantial area of the second recording layer has not yet been recorded and the user decides that the disk needed to be prepared for use in such a reading device, it is necessary to record a large area, resulting in tedious delays for the user.

Thus, the object of the invention is the provision of method, recording medium and recording device to avoid delays when the recording medium should be prepared for use in the reader.

According to the first aspect of the invention the task is solved by the method of recording information by writing marks in a track on the recording layer via a beam of radiation that penetrates through the front surface of the recording medium, the recording medium includes the first layer to record and the second record layer, the first record layer is in the position closer to the front surface than the second recording layer, each recording layer includes a pattern of grooves preliminary layout showing the position of the track, and the track on the first recording layer passes spirally in a first direction, and the track on the second recording layer passes spirally in a second direction opposite the first direction, with the formation of a two-part recording area, logically interrupted by an intermediate zone that is physically formed by the first intermediate part located at the end of the first recording layer and the second intermediate part located in the beginning of the first recording layer moreover , the recording area is preceded by an introductory area at the beginning of the first recording layer, and it should lead information at the end of the second recording layer, the method includes a step of writing the leadout containing the record in the outer lead part and the inner lead parts, and two parts separated unrecorded region and together form the outlet zone on the second recording layer, with the inner lead portion is recorded in a predetermined range of radial positions, covering a range of radial positions used by readers to access the second recording layer during the procedure is agrusti disk and the outer lead part is written in the end region of the second layer records containing user information.

According to the second aspect of the invention the task is solved by means of the recording media according to claim 7. According to a third aspect of the invention the task is solved by means of a recording device according to claim 9.

The measures taken resulted in the inner lead part is written in a relatively small area of the recording medium where the reader will access to the second recording layer. In addition, at the end of the recorded user data will be written to the external lead portion in a relatively small area. Therefore, to account for both areas require only a limited amount of time, because the area between the inner and outer parts of the remains unwritten.

The invention is also based on the following consideration. The recording media should be read in existing reading devices, such as DVD (digital versatile disk). The reader will carry out the procedure boot disk predictable way; in particular, it is necessary that every reader has learned predetermined control data from a known area on the first recording layer as the recording media must be formatted according to serene the particular standard. The inventors have found that in this procedure, the load should be expected to read test for the second recording layer, and it will take place in a predictable radial position, in particular around the radial position corresponding to the management data on the first recording layer. Therefore, in practical standardized environment, you can define a pre-set range, which should be recorded on the second layer, and only in this area should be recorded, forming the inner lead part. When further entry external lead part at the end of the recorded user data lead area effectively split into two written parts, between which there is a significant unrecorded area. Unrecorded area in no way will interfere with the reader.

According to a variant of the method the step of writing the leadout contains the initial write the leadout for recording the inner lead part during the initialization of the recording medium for use in recording or reading device and the stage of finalizing the leadout for recording external lead part after recording user information. The stage of finalizing the leadout can occur when finalizing the recording media for use in the device is read-only. The advantage with the her is at the end of the recording session you want to record only the outer lead part, which further reduces the latency for the user.

Other preferred embodiments of the method and device conforming to the invention described in the claims.

These and other aspects of the invention are readily available from the embodiments described by way of example in the following description and with reference to the accompanying drawings, in which

figa - disk recording media (top view),

fig.1b - recording media in the context of,

figs is an example of lobularia track,

figure 2 - recording device having a recording function of the leadout,

figure 3 - multi-layer optical disk,

4 is a diagram of the recording media with recoil tracks,

In the drawings, elements which correspond to the already described elements denoted by the same reference position.

On figa shows the disk medium 11 records with the track 9 and the Central hole 10. Track 9 is placed in accordance with a spiral pattern of the coils, forming essentially parallel track on the information layer. The recording medium may be an optical disk having an information layer of a recordable type. Examples of a recordable disc are the CD-R, CD-RW, and DVD+RW. Track 9 on the recording medium recordable type specified structure is dependent on the track of the preliminary layout, provided in the manufacture of blank recording media, for example by a groove in the preliminary layout. Recorded information on the information layer by optically recorded marks recorded along the track. Marks formed due to the changes of the first physical parameter and, therefore, have optical properties different from the properties of the environment. Labels detectable due to the changes of the reflected beam, for example changes in the reflection.

On fig.1b shows a view in section, taken along the line b-b of the carrier 11 recording a recordable type, in which the transparent substrate 15 provided with a recording layer 16 and a protective layer 17. The structure of the carriage pre-formed markup, for example, the groove 14 of the preliminary layout, which allows the head read/write, follow the track 9 during scanning. The groove 14 preliminary marking may be implemented as a notch or exaltation, or may consist of a material optical property different from the optical properties of the material of the groove of the preliminary layout. Groove preliminary marking allows the head read/write, follow the track 9 during scanning. Structure preliminary layout can also be formed uniformly distributed subdrainage or dimples preliminary marking, which is periodically cause of zerosignal. The recording media can be used to transfer information, reproduced in real time, such as video or audio, or other information, such as computer data.

On figs shows an example of lobularia track, which shows a periodic change in the transverse position of the track, also called lobularia. Changes cause the occurrence of the additional signal in the auxiliary detectors, for example in push-pull channel, generated by the partial detectors in a Central spot in the head scanning device. Lobularia, for example, is frequency-modulated and the information is position encoded in the modulation. A comprehensive description of lobularia, corresponding to the prior art shown in figs, the system recorded a CD containing the information disk, coded so you can find US 4,901,300 (PHN 12.398) and US 5,187,699 (PHQ 88.002).

During readout by scanning the modulation lobularia detected by the second type of radiation changes, such as changes in intensity in the cross section of the reflected beam detected by the detector segments or more detectors to generate zerosignal tracking. Detection of lobularia for tracking servosystem is well known from the above-mentioned system CD-R and CD-RW. Modulati is lobularia is used to encode physical address and control information, for example, in the system, DVD+RW and WO 00/43996. The way you write the leadout information that meets the invention relates to multi-layer recording medium. Note that the "top" (and "bottom") layer specifies the layer that is closest to (and the layer remote from the input surface of the laser, which in practice may be top or the bottom of the recording medium depending on the position of the laser.

According to a variant implementation of the recording medium has a modulation track preview markup to encode pin control information indicating that the pin information must be written in two parts, for example in a predetermined management area, which is schematically indicated by the area 12 on figa. Lead the management information can be encoded in ADIP, as described in WO 00/43996. Alternative lead the management information encoded in pits preliminary marking, as in DVD-RW, or in a pre-embossed area data using pits and playgrounds, as in the read-only drive. Lead the management information indicates the recording lead the field in two parts for phase write the leadout containing the record in the outer lead part and the inner lead part, as described below, such as the location of the inner lead part of the lead area on the bottom layer of the recording.

Figure 2 shows recording the e device having a function to write the leadout. The device is equipped with means for scanning the track on the recording medium 11, these means include a module 21 of the actuator to rotate the recording medium 11, a head 22, the servo terminal 25 for positioning the head 22 on the track and the control module 20. The head 22 includes an optical system of a known type for generating a radiation beam 24 directed through the optical elements, focused on the spot 23 on a track of the information layer of the recording medium. The beam 24 is generated by the radiation source, for example a semiconductor laser. The head also includes (not shown) Executive focusing mechanism to move the focus of the radiation beam 24 along the optical axis of the beam and the actuator tracking for precise positioning of the spot 23 in a radial direction on the center track. Executive tracking mechanism may include a coil for radial movement of the optical element or may be adapted to change the angle of the reflective element. Actuators focusing and tracking are driven by signals of the actuators from the servo terminal 25. To read the radiation reflected by the information layer is recorded by the detector of a usual type, such as four-quadrant diode, in th is information 22, generating detector signals input to the module 31 pre-processing for generating various signals of the scan, including the main scanning signal 33 and the error signals 35 for tracking and focusing. The error signals 35 act on the servo terminal 25 to the actuator control tracking and focusing. The error signals 35 also receives the demodulation module 32 track preview markup to retrieve the physical address and other control information from the figure tracks the preliminary layout. The main scanning signal 33 is processed by the module 30, the processing of reading well-known type including a demodulator, a tool deformirovaniya and an output module to retrieve information.

The device is equipped with a recorder for recording information on a recording medium recordable or rewritable type, such as CD-R or CD-RW, or DVD+RW, or BD. The writer communicates with the cylinder 22 and the block 31 pre-processing to generate a radiation beam recording and provides a means of processing the records for processing the input information to generate a recording signal for excitation of the head 22, the tool processing record includes an input unit 27, the tool 28 formation and a modulator 29. For recording information, the radiation beam is subjected to the UE is the t to create optically recorded marks in the recording layer. Labels can be any optically readable form, such as form fields with reflection coefficient, other than that of the environment, obtained when recording in materials such as dye, alloy or material with the possibility of a phase transition, or in the form of areas with a polarization direction other than that of the environment, obtained when recording in a magneto-optical material.

Recording and reading of information for recording on optical discs and formatting rules error correction and channel coding is widely known in the art, for example from the system CD or DVD. According to a variant implementation, the input module 27 contains a compression tool for input signals such as analog audio and/or video or digital uncompressed audio/video. Appropriate means of compression described for video in the MPEG standards, MPEG-1 specified in ISO/IEC 11172 MPEG-2 specified in ISO/IEC 13818. The input signal may alternatively be pre-coded according to the same standards.

The control module 20 controls the recording and retrieval of information, or may be adapted to receive commands from a user or from a host computer. The control module 20 is connected via control lines 26, such as the system bus to other modules in the device. The control module 20 includes a control circuit such as a microprocessor, program memory, and interfaces for which sushestvennee procedures and functions, described below. The control module 20 may also be implemented as a state machine in logic circuits. According to the invention the control module has an output module 36 to write the leadout in two parts, as described below. According to a variant implementation of the output module by removing the pin control information from the grooves of the preliminary layout by block wobulation demodulation 32.

Figure 3 shows a multilayer optical disk. L0 is the first record layer 40 and L1 is the second record layer 41. The first transparent layer 43 covers the first recording layer, the separator layer 42 separates the two layer record 40, 41 and the layer 44 of the substrate shown under the second recording layer 41. The first record layer 40 is closer to the input surface 47 of the recording medium than the second recording layer 41. The laser beam is shown in the first state, 45 as it is focused on the layer L0, and the laser beam is shown in the second state 46 as it is focused on the layer L1. Multilayer disks currently available as a pre-recorded disks, read-only, such as DVD-ROM or DVD-Video. Double-layer DVD+R disc has been proposed recently, and this disc should preferably be compatible with a standard dual-layer DVD-ROM. The levels reflect both layers >18%. The layer L0 has a transmittance of about 50-70%. The separating layer separates the layers tipi is Noah thickness from 30 to 60 μm. Layer L1 has a high reflectivity and must be very sensitive. In addition, the proposed rewritable dual layer discs. The layer L0 has a transmittance of 40-60%. Effective reflection of both layers is typically 7%, though lower and higher values (3-18%). Also considered recordable and rewritable optical media having 3 or more layers of the recording.

Because of the need for compatibility with existing standard recording media is read-only, such as standard DVD-ROM, dual layer recordable (or rewritable) DVD there are two possibilities for the disk layout. These two possibilities are called "parallel move tracks" (PTP) and "reverse track" (OTP), each of which indicates the direction of the spiral in both layers. In the PTP discs one by one to the information area on the layer (only two), while the drive OTP you have only one information area covering two layers. In the standard DVD-ROM dual layer disks using reverse tracks (OTP) is set to one information area covering two layers.

Figure 4 schematically shows the recording media with recoil tracks. The horizontal arrow 51 indicates the radial position (increasing output), and the vertical arrow 52 indicates physically the e address i.e. the number of sectors. Curve 49 indicates increasing addresses on the layer L0 40 in an outward direction, and curve 50 indicates the address on the layer L1 41, further increasing towards the inside. Zone record has the first data area 54 on L0 and the second part 57 on L1, between which is the average area formed by the first intermediate part 55 on the end of the recording layer L0 40 and the second intermediate part 56 at the beginning (in the direction of the track) recording layer L1 41. The arrows in the areas of data 54, 57 indicate the direction of the spiral. Before recording area is an introductory area 53 at the beginning of the recording layer L0, and after it is input area 58 at the end of the recording layer L1. Note that the multi-layer disk having more than two layers may have a third staging area at the end of the second recording layer and the fourth intermediate region in the beginning of the third recording layer, etc. Lead area completes the last layer of the recording. Hereinafter, the terms "lower layer" or "layer L1" two-layer disk are used to explain the invention, which, as expected, has the lower layers in the case of disks with more than two layers.

In the General case, standard DVD player expects data on both layers everywhere on dual layer DVD. In the case of double-layer DVD+R imposed the requirement that recorded double-layer DVD+R also contained data everywhere, i.e. both layers must be completely Zap lnany data. In the case of an account that does not use the full available capacity of the disk, the remaining empty portion should in principle be filled by the outlet region that does not contain user data for 100%compatibility with double-layer DVD-ROM. The filling is undesirable because this procedure is very time consuming, leading to unacceptably long time formatting and/or finalized after recording disk. In a single-layer DVD+R in order to avoid filling the remaining empty space is defined leadout limited length (320 blocks of code with error correction (ECC)) at the end of zone data, and the remainder of the disk is blank. However, in the case of a two-layer disk leaving the remainder of the disk is empty, i.e. especially (large parts of) more deep superficial layer L1, creates a problem, which is that the DVD player which tries to access this layer L1, unable to do that because he finds no data. Access to both layers L0 and L1, for example, be regarded as a typical situation in the DVD player at the beginning of read the newly inserted disk, for example, to adjust parameters such as focus shift for both layers. Failure when reading layer L1 will lead to a complete inability to read such a disk, even if the layer L1 is not user data.

According to the invention is uvodna area is recorded as the outer lead part and the inner lead portion, moreover, the two pieces are separated unrecorded region and together constitute a quasi-CW output area on the recording layer L1. The inner lead part covers predefined range of radial positions corresponding to the range of radial positions used by readers to access the second recording layer during the procedure boot disk. The outer lead part is written at the end of the user data on the recording layer L1. Therefore, the outer lead part specifies the end of the recorded data and causes the DVD player to stop reading when the end user data. The outer lead part can be limited in size (for DVD usually 320 ECC blocks). The inner lead portion is recorded on the layer L1 on the inner radial side of the disc in the area reserved for the leadout. The inner lead part can start a little earlier at the end of zone data immediately before a predetermined outlet area. The inner lead part is important in the case when the DVD player performs a jump between layers to access L1, for example at the beginning of the reading.

According to a variant implementation of the internal lead portion already recorded in the first recording session, for example, when a separate disk initialization or as a routine background is recording. This reduces the time required for the disc is finalized at the end of the recording session. Record output when the initialization is beneficial for other reasons, for example, to create a focus area on the recording layer L1. Initialization is performed before the start of the recording process. Record the inner lead part can also be done in the background during the recording of data, for example, during video recording with variable speed for some time will be available for the task of recording in the background. This reduces the initialization time required before writing.

Figure 5 shows the leadout recorded in two parts. Zone record has the first data area 54, in which the user data recorded on the layer L0 40, and the second part 60 on the layer L1 41, divided by the average area formed by the first intermediate part 55 at the end of the recording layer L0 40 and the second intermediate part 56 at the beginning (in the direction of the track) recording layer L1 41. Zone record is preceded by an introductory area 53 at the beginning of the recording layer L0, and it is followed by the lead area 64 at the end of the recording layer L1. Introductory area 53 is located on L0 and takes place from radius to 22.6 mm to a radius of 24.0 mm leadin should contain information management and should always be present when the disks to be read by a standard DVD player. However, lead area 64 has not prescribed the wow content. At the end of the recorded user data in the data area 61 on the layer L1 is written to the first lead portion 62, which contains the output that tells the DVD player what data is no longer recorded. DVD players also access layer L1 during the startup procedure when detecting the type of a newly inserted disk. The DVD player will attempt to access the layer L1 to determine that you have installed the double-layer disc. Access during startup occurs near a predetermined radial position, in particular near the end of the induction zone. Figure 5 shows the second lead portion 63, recorded near the access point DVD players, in particular near the radial position R=24, as indicated. Between the first lead part 62 and the second lead part 63 is unrecorded region 65. Unrecorded region 65 may be of a substantial length, if the user decides to stop recording when only a small part of the second recording layer contains the user data. For a disk that has more than two layers, additional lead part can be recorded on the respective radial positions. Thanks to write the leadout in two or more separate parts, you can achieve a significant reduction of formatting or finalization partially recorded double-layer DVD+R, then W is time ensuring maximum compatibility with reading existing DVD players.

In a specific embodiment, a double-layer DVD+R is a data area in the L0 since the radius 24,000 mm, and the data area in the L1 ends at a radius of 24,000 mm; after data zones inward in L1 can be culled area. In the same radial position as that of the exit zone in L1, the lead-in area data management is on the layer L0. Normal DVD players access layer L1 (for example, to calibrate the offset of the focus) by direct jump between layers in a radial position, where the control data on the layer L0 (near radius 24,000 mm). Therefore, the inner lead part enough to write output near this radius. To determine the size of the output to be written, you need to consider, for example, typical values of eccentricity between L0 and L1. In a practical embodiment, the inner lead part is written from 23,80 to 24,20 mm

According to a variant of implementation, in addition to the recorded region in the vicinity of the radius of 24 mm at the end of the user data is recorded additional output in the end of the recorded area. In addition, according to a variant implementation stage write the leadout includes a step of writing data fill in additional parts of the track in the other radial positions of the recording media, in particular Ni is sustained fashion pieces are placed in the intermediate parts. For compatibility with the drives read-only, you may want to record other areas of the recording media. Therefore, data filling, for example data blocks filled with zero data or prescribed values according to the standard, recorded in additional parts of the track, where the expected access to the lower layer. For example, when recording real-time data such as video, may be impossible to write the intermediate part, and the playback device can also try to access another(them) layer(s) in the intermediate zone. Therefore, when the record ends with the writing of the lead parts, the intermediate part is additionally recorded by writing data fill, at least partially, in the radial region where the expected access to the lower layer.

Although the invention has been mainly explained by embodiments using optical disc, based on the change in reflection, the invention is also applicable to other recording media, such as rectangular optical cards, magneto-optical disks, or the data storage system of any other type, which has a pre-imposed pattern recorded on the recording medium.
