The technical field to which the invention relates.

This invention relates to one-time writable disk and, in more detail, the recording method and device for recording data on a single recordable disk for faster access to the information required to use once recordable disc, and once recordable disc, used with the above method and device.

Prior art

New information can be repeatedly recorded on a rewritable disk, on which information has already been recorded. However, when new information is recorded on a single recordable disc, since the information that has already been recorded, cannot be erased or re-recorded in the place where the information has already been recorded, should be allocated a new place to update the already recorded information.

In General, only significant information, which was finally updated. Therefore, in order to read information that has been updated finally, the update region is allocated in the data area, and a device for recording and/or reproducing data reveals information that has been updated finally, searching the update region, which contains updated information. When the update region recorded a large amount of information the purpose, requires excessive time to find the desired information.

At once recordable disc, for which defect management is performed using the recorder and/or playback of data, there are areas for recording information for managing defects formed using once recordable disc, and information indicating the state of the write once recordable disc. Unlike a rewritable disc, according to the characteristic once recordable disc, as the updated information may not be recorded several times in the place where it was written pre-existing information, when you want to update the information of the defect management, the updated information must be recorded in the empty place. Accordingly, requires a relatively large area update. In General, the update region is allocated in the initial region or target region. However, sometimes the update region can be allocated in the data region in order to increase the number of updates that are assigned by the user.

When finally updated the information required to use once recordable disc that is recorded in the update region allocated in the data area, and when information indicating that the update region allocated to the data region, and information indicating the location area update included in this completely updated information, the information is permanently updated, or the location where recorded permanently updated information cannot be detected, even if you will review all the update region allocated in the initial region or target area.

Even if the recorder and/or playback of the data determines that the finally updated information recorded in the update region allocated in the data area, if the size of the update region is great for search finally updated information recorded in the update region, may require excessive time.

Description of the variants of embodiment of the invention

Now reference will be made to the details of existing options voploscheni the present invention, examples of which are illustrated in the attached drawings, in which everywhere the same reference numbers refer to identical elements. Variants of the embodiment described below in order to explain the invention with reference to the drawings.

Figa and 1B are structures once recordable disc according to a variant of embodiment of the present invention. Figa is a structure once recordable disc having a single recording layer, and FIGU is a structure once recordable disc with dual layer write.

Once recordable disc having a single recording layer, figa includes the initial area, the data area and the target area, placed in order from the inner circumference to the outer circumference.

Each of the first layer L0 recording and the second layer L1 write-once recordable disc having two recording layer, figv includes the initial area, the data area and the target area, placed in order from the inner circumference to the outer circumference.

Figure 2 is a detailed structure once recordable disc having a single recording layer according to a variant of embodiment of the present invention. Refer to figure 2, where the initial area includes a first area (DMA1) disk management, the second area (DMA2) in the manage disk the first staging area (TDMA1) disk management, area (AIA) information access and the scope of the test recording conditions. The target region includes a third region (DMA3) disk management and a fourth region (DMA4) disk management. Also, the target region may additionally include at least one of the temporary management defects, the field of test recording conditions and AIA. There may be at least one from each of the AIA, DMA, TDMA and field test recording conditions in at least one of the starting area and the target area.

AIA is an area intended for writing information access that specifies the location in which the recorded information updates, such as information management defects, which should get the recorder and/or playback to use once recordable disc. Information access and AIA will be described later.

The data region includes a first backup area, a user data area, the second temporal region (TDMA2) control disk and the second backup area.

TDMA1 included in the initial area is assigned during production, based on the specifications once recordable disc according to this variant embodiment. However, the first backup area, TDMA2, and the second backup is blast, included in the data area are allocated in the data area of the user's choice in the initialization process once a writable disk.

Figa and 3B are detailed structures once recordable disc having two recording layer according to a variant of embodiment of the present invention. Figa is the structure of the first layer L0 recording and figv is the structure of the second layer L1 of the recording. The structure of the first layer L0 recording shown in figa, identical to the structure once recordable disc having a single recording layer, shown in figure 2. The structure of the second layer L1 recording shown in figv, similar to the structure of the first layer L0 recording. However, in the structure of the second layer L1 recording AIA is not selected in the second inner region, and two TDMA allocated in the second data area.

Once recordable disc having two recording layer, includes five TDMA, TDMA1-TDMA5. Location and dimensions of the TDMA1 and TDMA2 known to the recorder and/or playback. However, TDMA3, TDMA4 and TDMA5 are allocated in the data region by the user or by the recorder and/or playback, when you initialize a disk for use once recordable disc having two recording layer.

Figa and 4B are detailed structures once recordable disc having two recording layer, according to another in which the Rianta embodiment of the present invention. Figa is the structure of the first layer L0 recording and figv is the structure of the second layer LI account. TDMA1, and TDMA2 TDMA5 selected at once recordable disc having two recording layer shown in figa and 4B. That is in addition known TDMA1 and TDMA2 only TDMA5 selected in the second data region by the user or by the recorder and/or playback when initializing a disk for use once recordable disc having two recording layer.

Now will be described areas, such as TDMA allocated on a single recordable disc, and the recording process data in these areas.

TDMA is an area for recording temporary management structure of the disk (TDMS) to control once recordable disc before finalizing once recordable disc. Finishing once recordable disc is an operation that prevents once recordable disc can be re-written. When the data can no longer be written to once recordable disc by the user, or when the data cannot be additionally recorded on a single recordable disc, once recordable disc is finalized.

TDMS includes a temporary list (TDFL) defects of the disk, a temporary structure (TDDS) description of the disk and the bit map (SBM) space. TFL includes information specifies the area in which the formed defect, and information specifying the area of the substitution. TDDS, which is used to control the TDFL includes a location marker indicating the location in which TDFL is recorded, the location marker indicating the location where recorded SBM, information indicating the location and dimensions of the reserve areas highlighted in the areas of data and information specifying the location and size of TDMA allocated in the data region. SBM shows the status of the data write once recordable disc using bitmap by allocating different bit values to the clusters in which data is recorded in units of clusters, which are units of data records, and the clusters in which data is not recorded.

When once recordable disc is loaded in the recorder and/or playback completely updated TDMS, in particular completely updated TDDS must be quickly read and restored once recordable disc to use once recordable disc in the unit.

Usually, when once recordable disc is loaded in the recorder and/or playback device, the recording and/or playback device determines how to manage once zapisi the subject disk and how to record or reproduce data, by reading information from the initial area and/or target area. If the amount of data stored in the primary area and/or target region is large, a longer time is required to prepare a recording and / or playback after once recordable disc is loaded. Therefore, we use the concept TDMS, and TDMS, formed at that time, as data is written to once recordable disc or played with him, is recorded in the TDMA, which is separated from the management of defects and selected in the initial area and/or target area.

When once recordable disc is finalized, TDMS, i.e. TDFL and TDDS recorded in the TDMA, permanently recorded in the DMA, as well as access to information for quick use once recordable disc is possible with permission of the recorder and/or playback to read relevant information from management defects by storing in DMA only the final relevant information among the lists of TDFL and structures TDDS, which are updated and written to multiple times.

Figa and 5B illustrate the process of recording data in the user data area and the backup area, according to a variant of embodiment of the present invention.

Figa corresponds to the user data area, and figv about the means reserved area. The method of recording user data in the user data area includes a continuous recording mode and a random recording mode. User data are recorded continuously and sequentially in continuous recording mode and randomly in a random recording mode. Zone (1)-(7) indicate the units in which verified after entry.

The recording device records the user data in the zone (1) and checks recorded whether the user data is normal or in the zone (1) formed the defect. If the part has any defect is found, this part is marked as a defective area, i.e. the defect #1. Also the recorder overwrites the user data, which were recorded in the defect area #1 backup area. User data, which were recorded in the defect area #1 are overwritten in the back part of the area called the substitution #1. The recording device records the user data in the zone (2) and checks recorded whether the user data is normal or a defect formed in the area (2). If found, in which there was a defect, this part is marked as a defective area, i.e. the defect #2. Similarly generates a field replacement #2 corresponding to the area of the defect #2. Also in the area (3) is formed defect #3 and is formed replacement #3. In the zone (4) defective about the region does not exist, as part of that formed the defect is not found.

If the end operation #1 record predicted after the user data is written and verified, i.e. if the user presses the eject button, or if the recording of the user data allocated to a write operation has been completed, the recording device records information related to the defect #1, the defect #2 and defect #3, which are defective regions formed in the areas of (1)to(4), in the TDMA as a TDFL #1. The structure for the control of TDFL #1 is recorded in the TDMA as TDDS #1. The write operation is part of the work defined by the user's intention or desired action records. In this variant embodiment, the write operation indicates a period from when once recordable disc is loaded and the action of recording predetermined information is performed, before, when once recordable disc is unloaded from the recording device.

When once recordable disc is loaded again, the operation #2 recording starts, the record status in the field of test recording conditions are checked and the user data are recorded on the basis of the test result. That is, in operation #2 recording of the user data is recorded in zones (5)-(7) in the same way, according to the operation #1 record, and are formed defect #4, de is the project #5, replacement #4 and the substitution of #5. When finished #2 recording device records the information associated with the defect #4 and defect #5, in the TDMA as a TDFL #2. The structure for the control of TDFL #2 is recorded in the TDMA as TDDS #2.

As shown in figure 2, 3A, 3B, 4A and 4B, when many TDMA and reserve areas allocated for once recordable disc, these TDMA and reserve areas are used in a predefined order. For example, when the path data record used in once recordable disc having two recording layer, as shown in figa and 3B is the other by paths, i.e. the path where data is written from the first internal region of the first layer L0 recording to the first outer region of the first layer L0 recording and from the second internal region of the second layer L1 recording to the second outer region of the second layer L1 of the write data in the backup areas to be written, starting with the first backup area of the first layer L0 recording. When the first backup area is full, and the second backup area, the third reserved area back and fourth region are used in this order.

Similarly, the TDMS is recorded, starting with the TDMA1 the first layer L0 recording. When TDMA1 filled, updated TDMS is recorded in the TDMA2, selected in the second interior area of the second layer L1 of the recording. When TDMA2 is full, the newly updated TDMS is opisyvayutsya in TDMA3, selected in the first data region of the first layer L0 recording. In this variant embodiment of the TDMA1 and TDMA2 allocated in the internal areas of the recording layers are required for a single recordable disc. However, the region or regions TDMA allocated data regions may or may not be selected by the user. Therefore, the TDMS is recorded in a consistent way, starting with TDMA allocated in the internal areas of the recording layers. When TDMA allocated in the internal areas of the recording layers, filled, used TDMA allocated in the data region.

When finally updated TDMS is recorded in the TDMA allocated in the data area, once recordable disc is unloaded, and once recordable disc is again loaded into the recorder and/or playback, the recorder and/or playback should finally get updated TDMS to use this once recordable disc. However, the TDMS is recorded in the TDMA allocated in the data area, and the recorder and/or playback may not recognize the fact that the TDMS is recorded in the TDMA allocated in the data area until the drive will not access TDDS included in the TDMS. Also, even if the recorder and/or playback recognizes the fact that finally updated TDMS is recorded in the TDMA allocated in the data region, the EU and the size of this TDMA is great may require excessive time to search completely updated TDMS recorded in the TDMA.

To solve the problem, now will be offered three variants of the embodiment of the present invention. In these three variants of the embodiment, the access information (AI) specifies the location where the recorded information updates, such as TDMS, in particular TDDS. Information update specifies the information that the recorder and/or playback should recognize to use once recordable disc in the initial period, when once recordable disc is loaded in this device recording and/or playback. Also the area in which the recorded information pack, call the update region. In these three variants of the embodiment of the information pack is TDDS, and the update region is TDMA.

I. the First version of the incarnation

In this variant embodiment, at least one main AIA, is used to record the main AI highlighted in the initial area or inner area once recordable disc, and the subordinate AIA allocated in TDMA.

When once recordable disc is loaded, the recording and/or playback first gets the main AI, by accessing the main AIA. The recorder and/or playback recognizes TDMA, which eventually recorded the updated TDDS on the basis of the main AI, and then gets a subordinate AI, by accessing the lookup AIA in TDMA. As the recorder and/or playback can recognize the location where the recorded permanently updated TDDS in TDMA-based sub AI, the time required for the search is finally updated TDDS in TDMA, may be reduced.

AIA allocated for once recordable disc, shown in figure 2, 3A and 4A, is the main AIA, according to this variant embodiment. The size of the main AIA preferably, although not necessarily restricted to minimize the amount of main AI recorded in the main AIA, and account updates main AI, because more time is required to obtain the main AI, if the size of the main AIA is great, or highlighted many of the major AIA. To reduce the expense of updates main AI, when TDMA, which recorded the final TDDS is changed, the main AI is recorded in one recording unit main AIA.

6 is a data structure TDDS, according to the first variant embodiment of the present invention. In this variant embodiment, the data structure separate main AI is not defined, and TDDS is used as the main AI. As described above, the TDDS includes information of location areas TDMA allocated on a single recordable disc. As shown in figa and 3B, when the TDMA1-TDMA5 selected at once recordable disc, TDDS who engages in information location TDMA1-TDMA5.

In this variant embodiment of the recorder and/or playback can recognize TDMA, which recorded the final TDDS of several units of account in which recorded TDDS in the main AIA. The case in which TDMA1-TDMA5 selected at once recordable disc and used in order TDMA1, TDMA2, TDMA3, TDMA4 and TDMA5, will now be described in detail. If the main AI, i.e. TDDS, there is no record in the main AIA, the recording and/or playback recognizes that the final TDDS is recorded in the first TDMA, i.e. TDMA 1.

If TDDS is recorded only in the first block main AIA, the recording and/or playback recognizes that the final TDDS is recorded in the second TDMA, i.e. TDMA2. If TDDS is recorded in the first and second main blocks AIA, the recording and/or playback recognizes that the final TDDS is recorded in the third TDMA, i.e. TDMA3. Similarly, if the TDDS is recorded in the first and third blocks of the main AIA, the recording and/or playback recognizes that the final TDDS is recorded in the fourth TDMA, i.e. TDMA4. And if TDDS is recorded in the first to fourth blocks of the main AIA, the recording and/or playback recognizes that the final TDDS is recorded in the fifth TDMA, i.e. TDMA5.

As described above, the recording and/or playback recognizes TDMA, which recorded the final TDDS of several blocks of records in which the TDDS is recorded in a welcoming, the St AIA, and restores TDDS, permanently recorded in the main AIA. Accordingly, the recording and/or playback can recognize the location information TDMA from this TDDS.

According to this variant embodiment, the size of the main AIA depends on the number of TDMA allocated on a single recordable disc. That is, if N TDMA has at once recordable disc, the main AIA includes at least (N-1) blocks of records.

Preferably, though not necessary, to TDDS recorded as the main AI in the main AIA, several times were recorded in a single recording unit. If the size of the TDDS is equal to the size of one sector, 2 KB, and if the write block size of 64 KB, one TDDS can be re-recorded 32 times in a single record block. Format error correction, which allows the correction of errors, sector by sector, disclosed in U.S. patent #6,367,049. If one TDDS recorded again 32 times in a single record block size of 64 kilobytes, according to the format bug fixes, opened in U.S. patent #636,367,049, the possibility of successful recovery TDDS can be greatly increased. That is, even if the errors due to scratches appeared in the recording unit, in which TDDS, i.e. AI, re-recorded 32 times, if the correction of errors in relation to at least one of TDDS 32 re TDDS is possible, the recording and/or playback can get AI.

Now will be described subordinated AIA and the subordinate AI. Sub AIA is allocated, starting from the first block of each TDMA, and the size of the sub AIA depends on how many sub-regions, including sub AIA separated TDMA.

7 is a data structure TDMA, divided into sub AIA and many subareas. Like the main AIA, TDDS is used as a subform AI, and the recorder and/or playback recognizes the subregion in which the recorded final TDDS in TDMA multiple record blocks, which are recorded TDDS in the lookup AIA.

As in the case in which the main AI recorded in the main AIA, TDDS recorded as subordinate AI, can be re-recorded in a single record block.

As shown in Fig.7, TDMA is divided into first to M-th sub-region TDMA, and when these subregions are used consecutively in a direction from the first subregion of the TDMA to M-th sub-region TDMA, if TDDS not recorded in the lookup AIA, the recording and/or playback recognizes that the final TDDS is recorded in the first subregion of the TDMA, i.e. sub-region 1 TDMA.

If TDDS is recorded only in the first sub-block AIA, the recording and/or playback recognizes that the final TDDS is recorded in the second subregion of the TDMA, i.e. sub-region 2 TDMA. If TDDS is recorded in the first and second sub-blocks AIA, the recording and/or playback recognizes that TDDS recorded in the third sub-region TDMA, i.e. subarea 3 TDMA. According to this variant embodiment, the size of the sub AIA allocated in each TDMA, depends on the number of subfields allocated in each TDMA. That is, if M subdomains available in TDMA, sub AIA should include at least (M-1) blocks of records.

Fig illustrates the main AIA and subordinate AIA, according to a variant of embodiment of the present invention. Once recordable disc according to this variant embodiment is a disk in which only TDMA5 allocated in the data area initialization in order to use the disk, as shown in figa and 4B. The main AIA includes 4 of the record block. In this variant embodiment TDMA5 includes 35000 blocks and is divided into modules of 4000 units (excluding one module that contains only 3000 units). That is TDMA5 includes 9 sub-regions. Therefore, as described above, the sub AIA includes 8 units of account.

When once recordable disc is initialized or when used TDMA1, the main AI is not recorded in the main AIA. If the location where the recorded final TDDS, changed to TDMA2, the recording and/or playback indicates that the final TDDS is recorded in the TDMA2, recording TDDS in the first block main AIA.

If the location where the recorded final TDDS, changed to TDMA5, the device records and/or reproduces the I indicates that the final TDDS is recorded in the first sub-region TDMA5, recording TDDS in the second, third and fourth blocks of the main AIA.

Figa and 9B illustrate subordinate AIA, according to other variant embodiments of the present invention. Once recordable disc according to this variant embodiment is a disk in which TDMA3, TDMA4 and TDMA5 allocated in the data area when the initialization is complete for disk usage, as shown in figa and 3B. Therefore, as described above, since the 5 regions TDMA allocated, the main AIA includes 4 of the record block. In this variant embodiment, any of the TDMA3 and TDMA4 includes 16000 blocks, and TDMA5 includes 35000 units, as shown in Fig.

Figa illustrates the data structure TDMA3, and figv illustrates the data structure TDMA4. TDMA3 includes 4 sub-regions. Therefore subordinated to the AIA included in TDMA3, includes 3 of the record block. As TDMA4 is the same as TDMA3, sub AIA included in TDMA4, also includes 3 of the record block.

TDMA5 divided into modules of 4000 units of account (excluding one module that contains only 3000 units of account) and includes 9 sub-regions. Therefore, as described above, the sub AIA included in TDMA5, includes 8 units of account.

As described above, according to the first variant embodiment, the recording and/or playback can more quickly access the location, where the recorded final TDDS, recording the main AI in the main AIA parent and the AI in the lookup AIA.

Now will be described in more detail transaction in which the recorder and/or playback accesses a location where the recorded final TDDS on the basis of the main AI and subordinate AI.

According to the first variant embodiment, when once recordable disc on which is recorded the main AI and subordinate AI, is loaded into the recorder and/or playback, the recorder and/or playback accesses the main AIA. If the information is not recorded in the main AIA, the recording and/or playback decides that the final TDDS is recorded in the TDMA1, or once recordable disc is a blank disc, and accesses the TDMA1. If no data is recorded in the TDMA1, the recording and/or playback recognizes that once recordable disc is a blank disc and starts initializing for use once recordable disc. If the data recorded in the TDMA1, the recording and/or playback receives final TDDS of the TDMA1.

If the data recorded in the main AIA, the recording and/or playback restores TDDS, by accessing the block in which the data is recorded last. The recorder and/or playback recognize which block which is a block in which data is written last, and recognizes, in which TDMA recorded the final TDDS. Also the recorder and/or playback can recognize the size of the TDMA in which the recorded final TDDS from the restored TDDS, and to recognize whether the selected sub AIA in this TDMA information about the size.
