Description

Technical field

The present invention relates to a write-once recording medium, and more particularly, to a method of recording a temporary defect list on a write-once recording medium, a method for reproducing a temporary defect list, a recording device and / or playback of a temporary defect list, and a write-once recording medium.

State of the art

Defect management includes recording data that is recorded in a specific place on the recording medium (recording medium) in which the defect is formed, to another place on the recording medium when the data cannot be reproduced normally, thereby preventing data loss caused by the formation of defects .

Typically, defect management is classified into defect management using a linear replacement method and a sliding replacement method. The linear replacement method is the replacement of the data area in which the defect is formed by the data area of the spare area where the defect is not formed. The rolling substitution method does not use the data area where the defect is formed, and proceeds to the next data area and uses the next data area in which the defect is not generated.

Methods of linear substitution and sliding substitution are mainly applied to discs, such as DVD-RAM / RW (digital multifunction disc with random access / overwrite memory), on which data can be overwritten and which use random sampling.

Several solutions for implementing defect management using a recording device and / or reproducing data onto a write-once recording medium in which data recorded once cannot be deleted or erased have been previously discussed.

Now, defect management for a write-once recording medium by linear replacement will be described in detail. A data recording and / or reproducing apparatus that receives user data recording commands and user data from a host writes user data to cluster units, which are recording data units. After the device for recording and / or reproducing data performs a verification operation after recording, if the defect generates user data areas in the cluster where user data is recorded, the device for recording and / or reproducing data writes user data to the backup area included in the data area.

During a predetermined time period when the data is recorded or after the completion of a single data recording, the data recording and / or reproducing apparatus creates a temporary defect list (hereinafter referred to as TDFL) containing information about the location of the clusters in the user data area where the defects are generated, and information about replacement clusters in the backup area, where user data recorded in defective clusters is copied. Then, the data recording and / or reproducing apparatus writes the created TDFL to the temporary disk management area (hereinafter referred to as TDMA). Also, after the data recording and / or reproducing apparatus writes the created TDFL to TDMA, it records pointer information indicating the place where the TDFL is recorded.

When the write-once recording medium is reloaded into the data recording and / or reproducing apparatus, the data recording and / or reproducing apparatus reads the TDFL from the write-once recording medium and stores the read TDFL in the memory. When additional data is recorded on a write-once recording medium, if new defective clusters are formed, the data recording and / or reproducing apparatus overwrites the data recorded in the defective clusters into replacement clusters of the spare area. Thereafter, in addition to the TDFL stored in the memory unit, the data recording and / or reproducing apparatus creates a modified TDFL containing information about the location of the newly formed defective clusters and information about the location of the replaced clusters corresponding to the newly formed defective clusters, writes the modified TDMA and records pointer information indicating the place where the modified TDFL is recorded.

When the write-once recording medium is reloaded into a data recording and / or reproducing apparatus for reproducing user data, the data recording and / or reproducing apparatus first selects TDMA, obtains pointer information indicating a location where the changed TDFL is recorded, and receives the changed TDFL. The data recording and / or reproducing apparatus can then reproduce user data without error by referring to the modified TDFL.

As described above, since TDFL is critical information for reproducing user data, TDFL should be recorded with a high degree of reliability. Thus, during recording TDFL, the verification operation after recording is carried out in the same manner as during the recording of user data. Therefore, if a defective cluster is formed, data recorded in the defective cluster is transferred to another TDMA cluster.

According to the prior art, if the TDFL size corresponds to at least two clusters and the TDFL is recorded in at least two clusters, a post-write verification operation is performed and the TDFL is overwritten to other clusters if a defective cluster is formed. However, TDMA is smaller than the data area, and the amount of data that can be stored in TDMA is small. Accordingly, when defect management for TDFL is carried out in accordance with the prior art, TDMA is quickly used.

Disclosure of invention

According to an aspect of the present invention, there is provided a method and apparatus for recording TDFL in a write-once recording medium with a high degree of reliability and better utilization of the area designated for recording TDFL.

According to an aspect of the present invention, there is provided a method and apparatus for reproducing a TDFL recorded with a high degree of reliability and better use of the area designated for recording TDFL on a write-once recording medium.

According to an aspect of the present invention, there is provided a write-once recording medium that records TDFLs with a high degree of reliability and better utilization of the area designated for recording TDFLs.

In accordance with the present invention, it is possible to more efficiently use areas of a write-once recording medium and more reliably record and play back TDFLs. In particular, the post-recording verification process is performed during the recording of the TDFL, and the TDFL is rewritten to another cluster if a defective cluster is formed. Thus, TDFL can be recorded with a high degree of reliability. Here, when a defect is formed during the recording of TDFLs, the data recorded in the defective cluster is overwritten in the replacement cluster instead of overwriting the whole TDFL, while pointer information indicating the locations of the clusters where the TDFL is normally recorded is included in the TDDS, and the TDDS is recorded in TDMA. Thus, the space for TDMA is not quickly used.

Preferred Embodiment

Detailed references will now be made to embodiments of the present invention, examples of which are shown in the accompanying drawings, in which like reference numbers refer to like elements. Embodiments of the invention are described below to explain the present invention with reference to the drawings.

1 shows the structure of a write-once recording medium 100 in accordance with an embodiment of the present invention. The write-once recording medium 100 shown in FIG. 1 has a single recording layer including a start area, a data area, and an end area.

In the initial area, a control disc area 1 (DMA 1), a disc management area 2 (DMA 2), a primary temporary disc management area (TDMA), a test conditions recording area, and an information management area are provided. In the data area, a backup area 1 and a backup area 2 are provided for replacing defective clusters formed in the user data area, a secondary TDMA, and a user data area. In the final area, a control disc area 3 (DMA 3) and a disc management area 4 (DMA 4) are provided.

The TDFL and the temporary disc definition structure (hereinafter referred to as TDDS) are recorded in the primary TDMA and secondary TDMA. TDDS includes recordable location information of the test conditions recording area, write protection information, and information about the location and / or size of the spare areas 1 and 2 assigned to the data area. In particular, in an aspect of the present invention, TDDS includes pointer information indicating the location of the TDFL. TDDS and pointer information indicating the location of the TDFL will be described in detail later.

TDFL and TDDS are first recorded in the primary TDMA. After all of the primary TDMA is exhausted, the TDFL and TDDS are recorded in the secondary TDMA. Secondary TDMA included in the data area may or may not be assigned to a corresponding user command or command from a data recording and / or reproducing device, thereby allowing the user or manufacturer of the recording and / or reproducing device to more effectively use a write-once recording medium.

When the write-once recording medium 100 is loaded into the data recording and / or reproducing apparatus as shown in FIG. 2, the data recording and / or reproducing apparatus initializes to use the write-once recording medium 100. In other words, the data recording and / or reproducing apparatus reads information recorded in the start area and / or the end area, and determines how to control the write-once recording medium 100 and record data or reproduce data from the write-once recording medium 100. As the amount of data recorded in the start area and / or end area increases, the time required for the data recording and / or reproducing apparatus to prepare for the recording or reproducing process after loading the write-once recording medium 100 also increases. To solve these and / or other problems, the concepts of TDDS and TDFL are presented.

In other words, before the end of use of the write-once recording medium 100, the TDFL and TDDS are changed and recorded in the TDMA. After the write-once recording medium is completed, the significant modified TDFL and TDDS are recorded as a defect list (DFL) and disc definition structure (DDS) in one of the DOWs 1 through 4. Also when writing significant modified TDFL and TDDS to the DMA 1 through 4 , the write-once recording medium 100 may be reproduced in the apparatus for reproducing the re-recording medium 100.

2 is a block diagram of a data recording and / or reproducing apparatus in accordance with an embodiment of the present invention. 2, a data recording and / or reproducing apparatus includes a write / read unit 1, a control unit 2, and a memory unit 3. The write-once recording medium 100 has the same structure as the write-once recording medium having a single recording layer shown in FIG.

The write / read unit 1 writes data to the write-once recording medium 100 and / or reproduces data from the write-once recording medium 100 by controlling the control unit 2. During data recording, for checking the recorded data, the recorded data is read.

The control unit 2 controls all operations of the data recording and / or reproducing apparatus. Also, when data is recorded to and / or reproduced from the write-once recording medium 100, the control unit 2 creates the changed TDFL, writes the changed TDFL to the write-once recording medium 100, and writes the TDDS containing the pointer information indicating the location of the changed TDFL to TDMA whereby performing defect management. Although this is not required, it is understood that the control unit 2 may be a main or special target computer.

Updated TDFLs and TDDSs that are read from the write-once recording medium 100 are stored in the memory unit 3 when the write-once recording medium 100 is initialized for use. After that, if new user data is recorded, defect management is performed again, the control unit 2 creates a new modified TDFL, which includes information about the locations of the new defective clusters and information about the locations of the replacement clusters corresponding to the new defective clusters in the TDFL stored in the memory unit 3 writes the changed TDFLs to TDMA and writes pointer information indicating the place where the changed TDFLs are written to TDMA.

Now, with reference to FIG. 3, a method for recording TDFL on a write-once recording medium 100 in accordance with the present invention, which is performed by the data recording and / or reproducing apparatus shown in FIG. 2, will be described.

3 is a flowchart of a TDFL recording method in accordance with an embodiment of the present invention.

Although not shown in FIG. 3, when the write-once recording medium 100 is loaded into the recording and / or reproducing apparatus, initialization is performed to use the write-once recording medium 100. In other words, the control unit 2 reads the changed TDFL and TDDS from the write-once recording medium 100 and stores the read TDFL and TDDS into the memory unit 3.

After that, if user data and user data recording commands are input to the write-once recording medium 100 from a host (not shown), the control unit 2 reads the user data from the write-once recording medium 100 to predetermined blocks and performs a post-write check operation for verification of recorded data.

During a predetermined period of time when data is being recorded, or after the completion of a single data recording, the data recorder and / or data playback creates a new modified TDFL containing information about the locations of the new defective clusters and information about the locations of the replacement clusters corresponding to the new defective clusters, TDFL in TDMA and records TDDS including pointer information indicating the location where the modified TDFL is recorded in TDMA.

4 is a flowchart explaining in detail the creation of a TDFL in accordance with a post-write verification process. Here, data is processed in blocks of either sectors or clusters. A sector is the smallest unit of data that can be controlled by a computer's file system or application. A cluster is the smallest block of data that can be physically written to disk at a given point in time. In general, at least one sector constitutes a cluster.

The sector is divided into a physical sector and a logical sector. The physical sector is the area of the disk where data corresponding to the sector is written. The address used to locate the physical sector is called the physical sector number (PSN). A logical sector is a sector block used to manage data in a file system or application. Similarly, a logical sector number (LSN) is assigned to a logical sector.

The data recording and / or reproducing apparatus finds using PSN the location of the data to be recorded or reproduced on the write-once recording medium 100, manages all the data in logical sector blocks in a computer or application for recording or reproducing data, and locates the data locations using LSN . The relationship between the LSN and the PSN is displayed by the control unit 2 in accordance with the formation of the defect and the place where the data recording begins.

4, the letter A denotes a user data area, and the letter B denotes a spare area. In user data area A and spare area B, for a plurality of physical sectors (not shown), PSNs are sequentially assigned. LSNs are assigned to at least one physical sector block. However, LSNs are assigned to the replacement areas of the spare area B, excluding the defective areas in the user data area A in which the defects are generated. As a result, although the physical sector and the logical sector are the same in size, if defect areas are formed, the PSN and LSN become different.

The user data is recorded in the user data area A in accordance with the continuous recording mode or the irregular recording mode. In continuous recording mode, user data is recorded sequentially and continuously. In irregular recording mode, user data is recorded irregularly. Reference numbers 4-10 indicate the area of blocks in which the verification operation is performed after recording.

The data recording and / or reproducing device writes user data to the block area 4, then the data recording and / or playback device returns to the beginning of the block area 4 and checks whether the user data is normally recorded or defects are formed. If a cluster is detected in which a defect is formed, the cluster is identified as a defective cluster and designated as a defective region, i.e. defect # 1, as shown in FIG. 4.

Also, the recording and / or reproducing apparatus overwrites the user data recorded in the defect # 1 to the backup area B. The part of the backup area B where the user data is overwritten is designated as replacement # 1. Further, after recording user data in the block area 5, the data recording and / or reproducing device returns to the beginning of the block area 5 and checks whether the user data is normally recorded or if defects are formed. If at least one cluster in which a defect is detected is detected, this at least one cluster is designated as defect # 2. In the same manner as described above, replacement # 2 corresponding to defect # 2 is indicated. Also in the area 6 of the block, a defective area is indicated, i.e. defect # 3, and replacement # 3 corresponding to defect # 3. No defects were detected in area 6 of the block and there are no defective areas.

After completion of recording and verification to block area 7, if completion of recording operation # 1 is expected (i.e., if the user presses the upload button or recording of user data assigned to recording operation # 1 is completed), the data recording and / or reproducing device creates the previous TDFL stored in the memory unit 3, TDFL # 1, where the information about the places of defects # 1 to # 3, which are formed in the areas 4-7 of the block, and information about the places of replacements # 1 to # 3, corresponding to defects with # 1 to # 3 ,.

When the write-once recording medium 100 is again loaded into the data recording and / or reproducing apparatus, the control unit 2 reads the previously recorded TDFL # 1 from the write-once recording medium 100 and stores the read TDFL # 1 in the memory unit 3. After that, when the first recording operation # 2 begins, data is recorded and defect management is performed in the same manner as in the recording operation # 1.

In other words, in the write operation # 2, the verification after the user data is recorded is carried out from the regions 8-10 of the block, and thus defects # 4 and # 5 and corresponding replacements # 4 and # 5 are indicated. After the completion of the recording operation # 2, the data recording and / or reproducing device creates in the previous TDFL # 1 stored in the memory unit 3, TDFL # 2, where the information about the location of defects # 4 and # 5 and information about the replacements # 4 and # 5 is changed .

5 shows an exemplary TDFL. 5, the location information of all the defective clusters on the write-once recording medium 100 is included in the first TDFL column, and the location information of the replacement clusters corresponding to the defective clusters is included in the second TDFL column. In an aspect of this embodiment, the locations of the defective clusters or replacement clusters are indicated by PSNs corresponding to the first sectors of the defective clusters or replacement clusters. However, the locations of the defective clusters or replacement clusters can be indicated using PSNs corresponding to the last sectors of the defective clusters or replacement clusters, or by indexes indicating defective clusters or replacement clusters, in accordance with an aspect of the invention.

Returning to FIG. 3, a first TDFL is created, as described above, the control unit 2 writes the created TDFL to at least one TDMA cluster and checks the recorded TDFLs (step S510). As a result of the check, if the defective cluster is formed among the clusters where the TDFL is recorded, the control unit 2 overwrites the data recorded in the defective cluster to another TDMA cluster (operation S530).

Now will be described two exemplary options for performing verification after recording TDFL.

6 is intended to explain verification after recording TDFL in accordance with an embodiment of the present invention. According to the shown embodiment of the present invention, when a TDFL whose size is equal to the sizes of this plurality of clusters is recorded in the TDMA, the entire TDFL is recorded and then checked.

6, the size of the TDFL is equal to the size of three clusters including the first cluster 210, the second cluster 230, and the third cluster 250, and the TDFL is recorded in three clusters and then checked. As a result of the check, it is determined that the defect in the second cluster 230 is not formed. Therefore, the data recorded in the second cluster 230 is overwritten in the cluster 270 of the next third cluster 250. After checking the cluster 270, if it is determined that the defect is not formed in the cluster 270, the TDFL recording and pointer information indicating the locations of the clusters in which the TDFL is recorded are completed, is included in TDDS and TDDS is recorded in TDMA. In this case, the pointer information includes pointers indicating the location of the first cluster 210 and the third cluster 250, in which defects were not formed during the initial recording, and the location of the cluster 270, which replaces the defective second cluster 230.

FIG. 7 is shown for explaining verification after recording TDFL for another embodiment of the present invention. According to an embodiment of the present invention, TDFL has a size of three clusters. TDFL is recorded in the first cluster 310 and then checked. As a result of the check, it is determined that the defect is not formed in the first cluster 310. The TDFL is recorded in the second cluster 330 and then checked. As a result of the check, it was determined that the defect was formed in the second cluster 330. Thus, the TDFL recorded in the second cluster 330 is overwritten in the cluster 350 next to the defective second cluster 330. After checking the cluster 350, if it is determined that the defect is not formed in the cluster 350, TDFL is recorded in the third cluster 370 and checked. After checking the third cluster 370, if it is determined that the defect is not formed, the TDFL record is completed and pointer information indicating the locations of the clusters where the TDFL is recorded is included in the TDDS and the TDDS is recorded in the TDMA. As in the embodiment of FIG. 6, the pointer information includes pointers indicating the locations of the first cluster 310 and the third cluster 370, where defects were not formed during the initial recording, and the location of the cluster 350, which replaces the defective second cluster 330.

FIG. 8 shows exemplary pointer information indicating a TDFL location in accordance with an embodiment of the present invention. The pointer information shown in FIG. 8 includes k pointers 410, 430 and 450. The data recording and / or reproducing apparatus sequentially writes TDFL to k clusters by reproducing the pointer information shown in FIG. 8, and the locations of k clusters can be seen .

In this embodiment, the reference to the nth TDFL cluster (n is an integer range from 1 to k) has a size of 4 bytes. Also, pointer information is included in the TDDS. In other words, the TDDS includes pointer information indicating the location of the TDFL, information about the recording location of the test conditions recording area, the protection information recording and the location and / or size of the reserve area information assigned to the data area.

Since TDDS should include pointer information indicating the location of the TDFL, TDDS should always be recorded after recording the TDFL.

As described above, in accordance with the method and apparatus for recording TDFLs, TDFLs can be recorded with a high degree of reliability by performing a verification operation after recording during recording TDFLs and dubbing TDFLs to another cluster if a defective cluster is formed. Also, when a defect is formed during the recording of TDFLs, only data recorded in the defective cluster is recorded in the replacement cluster instead of overwriting the entire TDFL. In FIG. 3, in operation S550, pointer information indicating locations of clusters in which TDFLs are typically recorded is included in the TDDS and TDDS is recorded in the TDMA. Thus, it is possible to save the recording area in TDMA.

Now will be described a method and apparatus for reproducing TDFL in accordance with an embodiment of the present invention.

The TDFL reproducing apparatus uses the data recording and / or reproducing apparatus shown in FIG. 2. However, if the TDFL playback device is a playback-only device, the write / read unit 1 and the control unit 2 can only read data.

9 is a flowchart of a TDFL reproducing method in accordance with an embodiment of the present invention. Although not shown in the drawings, when the write-once recording medium 100 in which user data, TDFL and TDDS are recorded in accordance with the method described above is loaded into the recording and / or reproducing device, the control unit 2 initializes for using the medium 100 single-entry recordings. In other words, the basic data necessary for using and managing the write-once recording medium 100 is read from the write-once recording medium 100.

In particular, after placing and reading the changed TDDS, pointer information indicating the location of the changed TDFL is obtained from the changed TDDS (operation S610). The pointer information indicating the location of the modified TDFL has a structure as shown in FIG.

Since the control unit 2 can obtain from the information of the location indicator of the clusters where the changed TDFL is recorded and the order in which the TDFL is recorded in the clusters, it reads the changed TDFL (operation S630). The control unit 2 stores the changed TDDS and TDFL, which are read from the write-once recording medium 100, in the memory unit 3. The control unit 2 can perfectly reproduce user data recorded on the write-once recording medium 100 with reference to the TDDS and TDFL stored in the memory unit 3.

The present invention may also be embodied as computer readable codes in a computer readable recording medium. A computer-readable recording medium includes all kinds of recording devices that store data that can be read by a computer system. So, a computer-readable recording medium is ROM, RAM, CD-ROM, magnetic tape, a floppy disk and optical data memory and transmission through carrier waves, i.e. The Internet. Also, a computer-readable recording medium can be distributed among computer systems connected via a network, and computer-readable codes can be stored on it and executed in a decentralized form.

It will further be understood that the method of the present invention can be used in a variety of types of media in which TDMA is to be stored, including optical recording media (such as CD-R, DVD-R), rewritable media (such as CD-R / W, DVD-R / W, DVD-RAM), magnetic and magnetic optical media, and the following DVD makers such as Bluray discs, Advanced Optical Disc (AOD), E-DVD.

Although several embodiments of the present invention have been shown and described, it will be understood by one of ordinary skill in the art that substitutions can be made in this invention without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
