Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording / reproducing apparatus, a recording method, a reproducing method, and an information recording medium, and more particularly, to guarantee the reliability of data reproduction when a recording medium is defective or damaged, and deteriorates during repeated rewriting. The present invention relates to an information recording / reproducing apparatus, a recording method, a reproducing method, and an information recording medium for performing a replacement process performed for the purpose.

[0002]

2. Description of the Related Art A magnetic disk, a magneto-optical disk, and an optical disk are used as a disk recording medium in which a defective area generated on a recording medium is detected and recording information is recorded again in an area different from the defective area. No. An example of a disk recording medium on which such replacement processing is performed is, for example, a DVD-RAM (digital versatile disk-random access memory). For the replacement process and defect management method for this DVD-RAM, see "Nikkei Electronics 1997.10.20 (no.
1) pp.168-179 "describes the technology.

According to the above-mentioned known example, an area on a disk is divided into a plurality of zones, and each zone is provided with a user area where information is normally recorded and a spare area when a defect occurs on the disk. Is divided into spare areas used for Regarding the types of defects that occur on the disk, primary defects including initial defects found during disk initialization,
After the recording on the disc is completed, the recorded information is read again to determine whether or not correct recording has been performed, that is, it is classified into a secondary defect found when verifying is performed. When a primary defect is found, when the disk is initialized, it is determined to be a primary defective sector by, for example, a detection error of a sector ID indicating a physical address provided to indicate a recording area on the disk. The physical address included in the sector ID is registered in a primary defect list (PDL: primary defect list). When recording information on a disc,
At the time of reproduction, when a sector corresponding to the physical address registered in the primary defect list is approached during recording and reproduction, the sector is skipped so that recording and reproduction of information for the sector is not performed and the primary defect sector is not recorded. Recording and reproduction of information are resumed and continued from a later sector. Secondary defects are found by verifying the reproduction again after recording the information on the disc in order to ensure sufficient reproduction reliability of the recorded information. The above DVD-RA
In the case of M, the discovery of the secondary defect is included in each row by decoding the error correction code for 16 sector units, ie, one correction block unit, to which an error correction code is added and error correction processing performed at the time of reproduction is completed. A row in which the number of error bytes exceeds a certain number is determined to be defective, and if the number of rows determined to be defective exceeds the threshold value when the number of defective rows included in one sector or the number of defective rows included in one correction block exceeds a certain threshold. The sector or the correction block itself is determined as a secondary defect. A sector or a correction block determined to be a secondary defect is subjected to replacement processing, and a correction block including the sector determined to be a defect or the correction block itself determined to be a defect is provided in each zone on the disk. The replacement is recorded in the spare area. Further, the physical address of the first sector included in the correction block determined to be a secondary defect,
The physical address of the first sector included in the correction block recorded in the spare area by the replacement process is registered in a secondary defect list (SDL: secondary defect list). When reproducing the disk, when the head of the secondary defect is approached from the secondary defect list, the reproduction is stopped, the head sector corresponding to the replacement physical address existing in the spare area is accessed, and the reproduction of the corrected block is performed. Reproduction is resumed from the sector following the correction block registered as the next defect, and reproduction is continued. The primary defect list,
Regarding the secondary defect list, a recording area is provided in the innermost and outermost areas of the disc, and each time a new defective sector is found at the time of recording information, the latest primary defect list,
Recorded and updated as a secondary defect list.

[0004]

With the recent increase in the capacity of the disk recording medium, the disk recording medium has not only data information such as computer data, but also video information and audio transmitted continuously or intermittently in real time. It is expected to be used as a recording medium for recording information, compressed video information and compressed audio information generated by performing a compression process, or stream information generated by time-division multiplexing such compressed video and compressed audio. For data information, program data processed by a device such as a computer connected to a recording / reproducing device, disk management information for managing recorded information on a disk as a file, management of an unrecorded area, and disk information And control information including a reproduction method, editing information, and the like for the recorded information. The amount of such data information is small, but the importance of the information is very high. For example, if the disc management information cannot be reproduced, it is unclear what is recorded on the disc, and the recorded information cannot be reproduced, so the importance of the information is extremely high. Therefore, it is necessary to sufficiently ensure the reproduction reliability of such data information. However, there is no restriction that a certain amount of data information must be recorded or reproduced in a certain time.

[0005] On the other hand, stream information represented by video and audio is enormous in information volume and may be transmitted continuously or intermittently in real time such as digital broadcasting. When recording such stream information that is transmitted continuously or intermittently in real time on a disk recording medium, a certain amount of information is recorded or reproduced in a certain time, that is, it is necessary to secure a transfer rate. This is very important and is the maximum condition required for a disc recording medium. In other words, a sufficient transfer rate is required for the input rate of the stream information during recording, and a transfer rate capable of maintaining the output rate required for the stream information is required during reproduction. On the other hand, in the reproduction of the recorded stream information, even if some errors occur, it can be reproduced without any problem as long as it is within the correction capability range of the error correction code added at the time of recording,
Even if the correction becomes impossible, for example, in the case of a video, there is no problem except for the special reproduction such as the slow reproduction, as the frame is dropped in several frames of the video frame. That is, the importance of the information is low, and the reproduction reliability thereof may be lower than that in the case of recording data information.

[0006] In recent years, however, the recording target of a disk recording medium is both the data information and the stream information described above, and the recording is performed according to the properties of the respective recording information (the degree of importance of the information and the level of the transfer rate). It is necessary to control the method and the reproduction method. When the data information and the stream information are recorded on the same disk recording medium, the information is recorded with emphasis on the reproduction reliability by performing a replacement process for the secondary defect described in the prior art in the recording method, for example. In this case, there is a problem that the worst transfer rate of the disk recording medium may be lower than the transmission rate of the stream information. In this case, the recording of the information on the disk recording medium cannot be performed in time for the transmission of the stream information, and the middle of the information is not recorded. Further, at the time of reproduction, video and audio for stream information are interrupted. In particular, in the recording / reproducing apparatus for the DVD-RAM described in the prior art, the above problem is expected to frequently occur because the seek time of the head for reading information on the recording medium and the rotation setting time of the disk recording medium are long.
Also, when performing simultaneous recording / reproduction in which another recorded stream information is reproduced while recording the stream information even when the transfer rate of the disc recording medium is sufficiently higher than the transfer rate for the stream information. Also, when recording information having a higher transmission rate, such as high-definition video information, which is close to the transfer rate to a disk recording medium, the above-described problem frequently occurs.

Conversely, when recording is performed to prevent a decrease in the transfer rate of a disk recording medium by performing only skipping for a primary defect without performing replacement processing for a secondary defect, for example, in the same area on the disk. The data information recording area may be incorrect if the data information playback signal is degraded due to frequent rewriting, or if a defect that does not happen to be registered in the primary defect list occurs in the data information recording area. If the data cannot be corrected even by decoding the correction code, the data information cannot be used.
For example, if the uncorrectable data information is disc management information, normal access and playback of files managed on the disc recording medium become impossible, or another record information is accidentally overwritten during recording. The recorded disc loses precious record information, making the disc unusable.

Further, the current recording / reproducing apparatus for a disk recording medium performs skip processing for a primary defect and replacement processing for a secondary defect irrespective of data information and stream information to be recorded. Therefore, it is not suitable for recording stream information transmitted continuously or intermittently in real time. Also, in a recording / reproducing apparatus using a fixed magnetic disk in which the disk recording medium cannot be replaced with a removable disk recording medium such as an optical disk represented by a DVD-RAM or a magneto-optical disk, the stream information and the data described above are also used. A similar problem occurs when recording and reproducing information.

Accordingly, an object of the present invention is to provide an information recording / reproducing apparatus, a recording / reproducing method, and an information recording medium which solve the above-mentioned problems.

[0010]

In the present invention, an information recording / reproducing apparatus and a recording method for solving the above-mentioned problems are described in detail below. A primary defect including an initial defect found when a disk recording medium is initialized is described. And first information for requesting the disk recording medium to record and reproduce information of a certain amount of data for a certain period of time while managing a secondary defect found by reproduction immediately after recording of the information, and recording to the recording medium When recording the second information requiring the information reproduction reliability, the first information
A first recording process of recording information while skipping at least the primary defect area for the information of
For the second information, at least the primary defect area is skipped, the secondary defect area is determined by reproduction immediately after recording the information, and the information included in the area is re-recorded in the replacement area to record the information. This is solved by configuring an information recording / reproducing apparatus that selectively executes each of the second recording processes for performing the second recording process according to a recording command.

Regarding the reproducing method, a first reproducing process for reproducing the information while skipping at least the primary defect area for the first information, and a reproducing method for at least the primary defect area for the second information In addition to skipping, the reproduction is not performed on the secondary defect area, but the information included in the replacement area is reproduced for that area, and the reproduction of the information is repeated depending on the occurrence of a reading error included in the reproduction information. This problem is solved by configuring an information recording / reproducing device that selectively executes each of the second reproduction processes to be tried in accordance with a reproduction command.

[0012] Further, regarding the selection of the recording process at the time of recording the information on the disk recording medium performed in the information recording / reproducing apparatus, the first recording command instructing the selection of the first recording process, and the selection of the second recording process. Is selected in accordance with a second recording command instructing. Regarding the selection of the reproduction process at the time of reproducing the information from the disk recording medium, the selection is made according to a first reproduction instruction instructing the selection of the first reproduction process and a second reproduction instruction instructing the selection of the second reproduction process. Done.

The data transferred from the external connection device 8 includes compressed stream data that is continuously or intermittently transferred in real time, such as video and audio information, and data accompanying them.

FIG. 3 is a block diagram showing an example of a configuration in a case where a circuit for executing compression processing and decompression processing for input video and audio is provided in the recording / reproducing apparatus for the disk recording medium 1, and FIG. The same components are denoted by the same reference numerals and description thereof will be omitted. In FIG. 3, reference numeral 9 denotes video and audio compression in which compressed video data and compressed audio data are multiplexed to generate compressed stream information by compressing video or audio information transmitted continuously in real time in real time. The circuit 10 performs a decompression process on the compressed stream information recorded on the disk recording medium 1 and returns the original video and audio information to output video and audio decompression circuits, respectively. It is a selector for selecting information to be recorded on the disk recording medium 1 for each of the compressed stream, external data input, and external compressed stream.

Referring to FIG. 4, an example of the structure of the disk recording medium 1, area division, and recording information recorded in the divided areas will be described. 4A shows the physical structure and area division of the disk recording medium 1 and their respective configuration contents, and FIG. 4B shows the logical area of the disk recording medium 1 viewed from the external connection device in FIG. 2, for example. 2 shows the configuration of division and recording information. In FIG. 4A, the information is roughly divided into a lead-in area, a data area, and a lead-out area. The lead-in area includes disk information storing information indicating the type of the disk such as disk identification information, and a disk recording medium. A primary defect list that registers a physical address for a primary defect area including an initial defect discovered at the time of initialization, and a physical address for a secondary defect area discovered by verification performed after information is recorded on a disk recording medium. And at least a DMA (Defect Management Area) which is a recording area of a secondary defect list in which respective replacement start physical addresses when the recording information included in the secondary defect area is replaced are registered. You. Here, the primary defect area is constituted by, for example, a sector unit which is a recording unit on a disk recording medium, and the secondary defect area is constituted by a correction block unit in which error correction processing is completed. Further, regarding the lead-out area, D in the lead-in area
It comprises at least a DMA area in which the same primary defect list and secondary defect list as the MA are stored. Further, it constitutes a data area between the lead-in area and the lead-out area, which is a recording area for information on the disk recording medium 1. The data area is further divided into a plurality of zones at regular intervals, and zone 0 to zone N (N is a positive integer)
Is divided into Each zone is further divided into a user area and a spare area.The user area is a normal recording area for information, and the spare area is reserved for performing a replacement process on an area where a secondary defect has occurred. This area is reserved to compensate for the reduced user area due to the discovery of the user. A physical address number that specifies a position in the physical area is assigned a continuous physical address number from the beginning of the lead-in area to the end of the lead-out area, and the recording / reproducing apparatus detects the physical address and starts recording and reproducing. Specify the position and end position.

The logical area shown in FIG.
And a user area included in each zone from the beginning to the end of the data area constitutes a continuous logical area. The logical area handles at least volume descriptors, management information and other recording information in the physical area as files in the logical area, and a storage area for information necessary for management and a file corresponding to the recorded information,
Occupied by unrecorded area. The management table stores at least a file name for the recorded information, a hierarchical structure, link information of each file (playback order), and map information of a logical address corresponding to an unrecorded area. As for the logical address, for example, a logical address 0 is assigned to the head of the management table, and a logical address (L-1) is assigned virtually to the end of the logical area.
For example, when a transfer command is set in the system controller 7, the start and end of a file for information recorded by a logical address are specified, an unrecorded area is grasped from disk management information, and information about a file for recorded information is obtained. Generates recording and playback commands. Regarding the correspondence between the physical area and the logical area, for example, an area (sector) in which a primary defect has occurred in the physical area is not assigned a logical address in the logical area. That is, when a primary defect occurs, the primary defect area on the physical area is not allocated on the logical area.
Also, no logical address is assigned to the area in which the secondary defect has occurred, and instead, the logical address assigned to the area immediately before the secondary defect has occurred with respect to the storage area of the information recorded in the spare area where the replacement processing has been performed. The logical address following the address is successively assigned, and the logical address following the last assigned logical address of the replacement information storage area is successively assigned from the area immediately after the end of the secondary defect occurrence area. In other words, when a secondary defect occurs, continuous logical addresses are given in the logical area, and it appears that they are recorded in an apparently continuous area. However, in the actual physical area, part of the recorded information is stored in the spare area. That is, it is dispersed and recorded discontinuously. That is, at the time of recording and reproduction, it is necessary to move the head 2, access a replacement destination, and access immediately after the secondary defect area.

Hereinafter, an information recording operation performed in the recording / reproducing apparatus shown in FIGS. 2 and 3 will be described with reference to a flowchart of FIG. In FIG. 1, for example, when the disk recording medium 1 is a removable recording medium that can be replaced with a recording / reproducing apparatus, when a disk is inserted into the recording / reproducing apparatus, the system controller controls the head 2 and the digital signal processing circuit 4. Then, a lead-in area of the disk recording medium 1 is accessed and reproduced. When it is determined that the disc is a disc recording medium as shown in FIG. 4 by reproducing the disc information or the like, the primary defect list and the secondary defect list written in the DMA area are further read and temporarily stored. (Step 101). Further, by reproducing the volume descriptor and the management table in the logical area starting from the head position of the data area, the disc recording medium 1 is reproduced.
The information about the file existing above and the information about the unrecorded area are grasped (step 102). When information is recorded on the disk recording medium 1, the head logical address for a new information recording area is determined based on the logical address at the head of a recorded area in the logical area clarified from the disk management information and the logical address of the unrecorded area. A transfer command including at least a logical address, a recording command, and a transfer data amount is generated and set in the system controller 7. The system controller 7 determines from the received transfer command whether the content of the command is a recording command, a reproduction command, or another command (step 103). In step 104, the content of the transfer command is a recording command. It is determined whether the instruction is a continuous recording instruction for instructing selection of a recording process for stream information. The continuous recording command is a recording command for selecting a recording process which is suitable for recording stream information transmitted continuously or intermittently in real time and which does not place importance on the reliability when reproducing the recorded information. . If it is not a continuous recording command in step 104, step 105
Then, it is determined whether or not the transfer command is a non-continuous recording command instructing selection of a recording process for data information. If not, the process proceeds to step 103 to wait for reception of the next transfer command. The non-continuous recording command is a recording command for selecting a recording process suitable for recording data information that places importance on the reliability when reproducing the recorded information. If it is determined in step 105 that the command is a non-continuous recording command, the process proceeds to step 106 to access the physical address on the disk recording medium 1 corresponding to the specified logical address by moving the head 2, From there, recording is performed for the specified data amount. During the recording of the transferred information, at least the primary defect area registered in the primary defect list is skipped without performing recording on the area secured for recording. If it is desired to further improve the reproduction reliability during reproduction, the recording is skipped without performing the recording even on the secondary defect area registered in the secondary defect list. Further, after the recording of the specified data amount is completed, the physical address at which the recording was started is accessed and reproduced again (step 107).

A comparison is made between the number of error bytes clarified by decoding of the error correction code performed in the digital signal processing circuit 4 and a threshold value set in the system controller 7 and determined as a secondary defect (step 10).
8). In step 108, when the number of detected error bytes is equal to or larger than the threshold value, it is determined that a secondary defect has occurred, and for example, a spare area constituting the zone currently being reproduced is accessed, and the error area in which the secondary defect has occurred is determined. The replacement process is performed by re-recording all the recording data within the range in which the error correction including the error correction is completed in the free area in the spare area (step 109). In some cases, the processing from step 107 to step 109 is performed again on the data recorded in the spare area in the replacement processing, and the information re-recorded on the spare area is verified. After the recording, the head physical address of the secondary defect area and the head physical address of the spare area in the spare area are registered in the secondary defect list read when the disc is inserted (step 110).

The updated defect list is recorded in the DMA area and updated to the latest list when the recording / reproducing apparatus is in an idle state where recording or reproduction is not being performed or when a disc is taken out. If it is determined in step 104 that the content of the transfer command is a continuous recording command, the area of the physical address corresponding to the target logical address is accessed, and at least the primary defect list existing in the area reserved for recording is accessed. Recording is continuously started and continued while skipping the registered primary defect area. If it is desired to further increase the reproduction reliability during reproduction, the recording is skipped without continuing recording even in the secondary defect area registered in the secondary defect list and recording is continued (step 1).
11).

Further, the recording is continued unless it is determined in step 112 that the recording end command has been reached or the recording of the designated transfer data amount has not been reached. When the recording of the transfer data amount is completed, the recording on the disk 1 is stopped. However, after the recording is stopped, steps 107 to 110 are performed as in the recording according to the non-continuous recording command.
That is, the recording is terminated without performing the verifying process. Finally, in the logical area on the disk recording medium 1 when the recording / reproducing apparatus is in the idle state or when the disk is ejected, the file name of the file to be newly generated for the recording information, the hierarchical structure of the files, the start logical address By adding information and overwriting the recorded area, the information on the overwritten file is deleted from the management table, and when recording on the unrecorded area, the map information is updated. The management table is newly updated and recorded again in a predetermined area on the disk recording medium (step 113). When the management table is updated and recorded again, the processing from step 106 to step 110 according to the non-continuous recording command is performed, and the recording is performed with emphasis on the reproduction reliability.

The above-described continuous recording command is not limited to being generated only once before the start of recording, and may be performed in a unit of a certain data amount or at the end of recording for a certain period when recording information is intermittently transmitted. The command may be repeatedly generated later, and intermittent recording may be performed for each specified transfer data amount. Also in this case, the recording operation according to the continuous recording command of steps 103 to 112 in the flowchart of FIG. 1 is repeatedly performed.

Next, an information recording medium on which information is recorded according to the recording method of FIG. 1 will be described with reference to FIG. FIG. 4B shows steps 104 to 11 of FIG. 1 in a logical area for the disk recording medium 1.
1, the recording result of the stream information according to the continuous recording command over step 112 is shown. For example, recording is started as a stream file 1 from a logical address I (I is a positive integer) and a logical address (J-1) (J is a positive integer) when the recording is ended. 1 also shows a state of a recording result of data information in accordance with a discontinuous recording instruction in which a transfer data amount is specified in steps 105 to 110 in FIG. 1, for example, a data file corresponding to edit data of stream information or program data. Is a logical area from logical address J to (K-1) (K is a positive integer), and a storage location of data information in a management table for managing file information for recorded information in the logical area and managing unrecorded area. Logical address 0 to (H
1 shows a case where discontinuous recording is performed on a logical area up to -1) (H is a positive integer).

The physical area shown in FIG. 4A with respect to the area occupied by the stream file 1 in the logical area shown in FIG. 4B is, for example, from the middle of the user area 1 of the divided zone 1 to the area of the user area 2 of the zone 2. Recording is performed continuously halfway, but recording is performed in a discontinuous area without performing recording in the area including the spare area 1 used for the secondary defect replacement processing. As for the data file, the result of the replacement processing performed on the spare area determined as a secondary defect in the verification after the end of recording is shown. The secondary defect area generated in the middle of the data file recorded in the user area 2 is the spare area. 2 has been replaced. Similarly to the data file, when the secondary defect occurs, the management table is replaced with the spare area as a spare area. That is, when a secondary defect occurs and the replacement process is performed, the secondary defect area itself in the middle of the continuous area where the file exists is recorded in the spare area, and as a result, discontinuous recording is performed. Will be. That is, even when a small amount of data is reproduced during reproduction, the head 2 needs to be moved to the secondary defect area, so that the transfer rate during reproduction significantly decreases. However, a file that has been subjected to the replacement processing in accordance with the non-continuous recording instruction records information that may cause a decrease in the transfer rate, such as a data file and a management table. . However, recording with high reliability at the time of reproduction is performed. Regarding the stream file, the head moves when recording and reproducing across zones, but since the replacement process is not performed according to the continuous recording command, a decrease in the transfer rate of the disk recording medium during recording and reproducing is suppressed to a minimum. However, the reliability during reproduction depends on the recording state of the disk recording medium, and in some cases, the reliability may be low.

Next, as shown in FIG. 4, a stream file 1 recorded on the same disk recording medium in accordance with a continuous recording instruction and a data file or a management table in which replacement processing for a secondary defect is performed in accordance with a non-continuous recording instruction A reproduction operation performed by the recording / reproducing apparatus of FIGS. 2 and 3 on the disk recording medium 1 on which is recorded will be described with reference to a flowchart of FIG. However, the processing from step 501 to step 503 is equivalent to the processing from step 101 to step 103 in FIG. 1 and the description is omitted. It is determined in the analysis of the transfer instruction in step 503 that the instruction is a reproduction instruction, and it is determined in step 504 whether the instruction is a continuous reproduction instruction for instructing selection of reproduction processing for stream information. The continuous reproduction command is a reproduction command that is suitable for reproducing stream information that requires continuous or intermittent reproduction of information in real time and that does not place importance on reproduction reliability.
If the instruction is not a continuous reproduction instruction in step 504, the process proceeds to step 505 to determine whether the transfer instruction is a non-continuous reproduction instruction instructing selection of reproduction processing for data information. And waits for the reception of the next transfer instruction. The discontinuous reproduction command is a reproduction command suitable for reproducing data information with an emphasis on information reproduction reliability. If it is determined in step 505 that the command is a non-continuous reproduction command, the process proceeds to step 506 to access the physical address on the disk recording medium 1 corresponding to the specified logical address, and to specify the specified data amount Play for minutes. During reproduction, the initial defect area in the primary defect list is skipped without being reproduced, and the transfer to the secondary defect area in the secondary defect list is temporarily stopped and the replacement process is performed. After accessing and reproducing the recording area in the spare area thus performed, access and reproduction are again performed from an area subsequent to the secondary defect area, and reproduction of the recording information corresponding to the specified data amount is performed. If an error byte exceeding the correction capability of the error correction code added during recording on the disk recording medium 1 during reproduction in step 506 is generated and it is determined that correction is impossible (step 50).
7), a retry process for retrying reproduction for an uncorrectable area is performed, but before that, step 5
At 08, the number of times of retry execution is compared with a threshold value of the number of times of retry limit set in the system controller.
If the number of retries is equal to or greater than the threshold in step 508, it is determined that reproduction is impossible, and the reproduction process is stopped as it is.

If the number of retries does not exceed the threshold value in step 508, retry processing is performed by re-accessing and reproducing from the uncorrectable area, that is, the area within the range where error correction processing is completed. (Step 509), the determination in Step 507 is performed. If it is not determined in step 507 that the correction is impossible due to the retry processing, the reproduction is continued as it is, the processing is completed with the reproduction of the designated data amount, and if it is determined that the correction is impossible, the retry processing from step 508 is performed again. Do. If it is determined in step 504 that the content of the transfer command is a continuous recording command, the head of the area corresponding to the physical address corresponding to the target logical address is accessed, and at least the primary defect registered in the primary defect list is accessed. Continuous playback is performed while skipping the area. In some cases, the secondary defect area is skipped and recorded for the purpose of further improving the reproduction reliability at the time of recording. Therefore, while skipping the secondary defect area registered in the secondary defect list, In some cases, reproduction is performed continuously (step 513). In this case, unlike the discontinuous reproduction command, only the skip is performed for the secondary defective area, and the reproduction is temporarily stopped, the access to the alternate area is performed,
No regeneration takes place. Further, unless the reproduction end command is determined in step 514, or the reproduction of the specified data amount is not reached, the reproduction is continued, and if the reproduction end instruction is determined in step 514 or the reproduction of the specified data amount is performed. Upon completion, when the end of the file is detected, the reproduction is stopped. In the case of continuous reproduction, the processing from step 507 to step 509, that is, the retry processing due to the detection of the uncorrectable state is not performed as in the case of the non-continuous reproduction, and the reproduction processing is continued even if the correction is impossible.
For the reproduction of the management table in step 502, the reproduction processing in steps 506 to 509 is applied in accordance with the discontinuous reproduction command in step 505. As described above, a file reproduced according to the continuous reproduction command can be reproduced while suppressing a decrease in the transfer rate of the disk recording medium, and a file reproduced according to the non-continuous reproduction command performs a retry operation, and further performs a secondary defect. Since the reproduction is performed in combination with the data reproduction of the replacement destination according to the list, highly reliable reproduction is possible.

The above-mentioned continuous reproduction command is not limited to being generated only once before the start of reproduction.
Alternatively, the reproduction command may be repeatedly generated again after the end of the reproduction for a certain period, and intermittent reproduction may be performed for each specified data amount. Also in this case, the reproduction operation according to the continuous reproduction command of steps 503 to 514 in the flowchart of FIG. 5 is repeatedly performed.

(A-1) shows the correspondence between the stream file 1, the data file existing in the logical area, and the physical area. The stream file 1 does not perform the replacement process by detecting the secondary defect, and shows a case where the recording is performed across the user areas 1 and 2 of the zones 1 and 2. The data file and the management table are each processed by detecting the secondary defect. The figure shows a case where the replacement processing for the secondary defect area is performed and recorded in the spare area of the zone. (A-2) shows the result of performing a rearrangement process on the physical area for the data file, the management table, and the stream file.
FIG. 7 is a flowchart illustrating an example of a method of rearranging stream information recorded without performing detection and replacement processing of a secondary defect.

The rearrangement process for stream files in FIG. 6 will be described with reference to the flowchart in FIG. In FIG. 7, when a command for instructing the system controller of the recording / reproducing apparatus to execute the rearrangement processing is set (step 701), the recording area on the disk recording medium is accessed and reproduced for the file which becomes clear from the management table. (Step 702), and reproduction of recorded information in each zone is performed while skipping the primary defect area registered in the primary defect list and skipping the secondary defect area registered in the secondary defect list. , All error areas in the zone are detected by comparing the number of error bytes with the threshold value for determining a defect. If there is a file break in the middle of the zone, playback is performed up to the end of the file included in the zone, and an error area is detected by comparison with a threshold (step 703). In step 704, it is determined whether all the detected error areas can be rearranged from the unrecorded area and the remaining spare area existing in each zone. If the determination in step 704 is not satisfied, the process proceeds to step 708, the threshold value of the number of error bytes determined to be a defect is increased, the condition for determining a defect is relaxed, and all error areas detected earlier in step 703 are newly detected. The detection of is detected again. If the determination in step 704 is established, step 7
05, after the first error area found in each zone, or after the area where error correction processing including the error area is completed, and until the end of the zone, the recorded information up to the end of the zone is stored in another temporary storage means or on the disk recording medium. Temporarily save to a recording area. After the temporary saving of the recording information is completed, an error area detected for each zone in step 706,
Alternatively, the reordering is performed by re-recording in the order of the recording information in an area other than the area where the error correction processing is completed including the error area. Finally, the physical address for the error area newly determined as a defect in step 707 is added to the primary defect list, or the leading physical address of the area where the error correction processing including the error area is completed is added to the secondary defect list, or Are added to the primary defect list, and the DMAs on the disk recording medium are added.
It is updated and recorded in the area. However, when registering in the secondary defect list, the first physical address of the replacement destination is not registered.

FIG. 6 shows an example of a result obtained by rearranging information according to the method described with reference to FIG. In the stream file 1 shown in FIG. 6, a series of stream information is recorded over the user area 1 and the user area 2 in the physical area of the disk recording medium as shown in (A-1).
For example, it is assumed that an error area is newly detected in the user area 1 in the processing in step 703 of FIG. Then, as shown in (A-2), the information after the detected error area extends to the spare area and is re-recorded to be rearranged. Further, the detected error area is registered in the primary defect list or registered in the secondary defect list, so that the error area or the area where the error correction is completed including the error area is skipped during the reproduction according to the continuous reproduction command. Will be.

Since the stream information is recorded without performing replacement processing by secondary defect detection, the utilization rate of the spare area included in each zone is low. Therefore, the rearrangement process can be performed within the range of each zone as described above.

Next, the execution result of the rearrangement process for the record information subjected to the replacement process by the detection of the secondary defect such as the data file and the management table will be described with reference to FIG. In FIG. 6, for the management table subjected to the replacement process by the detection of the secondary defect, the recording information after the first secondary defect area included in the recording area for the management table is temporarily stored from the contents of the secondary defect list. The recording information of the replacement destination is re-recorded after the secondary defect area, and subsequently the recording information temporarily evacuated is recorded. There is no unrecorded area in the user area 0 depending on the information recording state. In this case, the information is recorded over the spare area and the rearrangement is performed. Further, the information on the secondary defect area and the replacement area for the area that was a secondary defect is deleted from the secondary defect list, and the information recorded in the DMA area is updated and recorded again. In FIG. 6, with respect to the data file subjected to the replacement process by the detection of the secondary defect, the recording area for the stream file 1 and the recording area for the data file are mixed in the same user area 2, and the recording area for the user area 2 of the stream file 1 The table shows the result of moving to the user area for the unrecorded area in another zone and rearranging the information included in the replacement area for the secondary defect area in order to sufficiently secure the area necessary for the rearrangement processing. It is. The recording area for the data file before the transfer is an unrecorded area, and is used for executing the rearrangement process on the recording information in the user area 2. Also in this case, the information on the secondary defect area and the replacement area corresponding to the secondary defect list is deleted from the secondary defect list, so that the recording information in the DMA area is updated and recorded again. Further, on the management table, the logical address of the data file is changed, the management map of the unrecorded area is changed, and the management table is updated and recorded.

The rearrangement process described above with reference to FIGS. 6 and 7 can select whether or not to execute the process, and is not limited to being performed without fail. If execution is selected, at least new information cannot be recorded or reproduced on the disk recording medium during the processing. In other words, the rearrangement process can be started when the information recording / reproducing device is in the idle state.

By rearranging the recording information within the range of each zone in the physical area of the disk recording medium described above, it is possible to improve the reliability when reproducing the stream information. In addition, since the reordering of recorded information is completed within each zone using the spare area, temporary storage means necessary to temporarily save the recorded information and the storage capacity of the unrecorded area on the disk recording medium can be saved. It is.

Further, the recording information included in the replacement area is rearranged for the data information which has been subjected to the replacement processing by the secondary defect, and the secondary defect area is re-registered in the primary defect list, thereby reproducing the data at the time of reproduction. It is possible to prevent a remarkable decrease in the transfer rate. By moving the recording information included in the file to another unrecorded or assignable zone, the stream information can be rearranged in a zone where data information and stream information are mixed.
