Abstract

In writing data to a storage medium not including a defect alternation function or writing data using a file system not including defect alternation information, a problem of a system becoming inoperable normally due to a response time from a reader/writer being long when data is written or read to/from a defective location in a storage medium is prevented. Detective location information indicating an error which occurred in reading or writing is recorded in an area which is not primarily for storing such information. By using the defective location information, the writing location is changed so as to prevent the data from being written to the defective location, and the file system information is rewritten.

Description

200837736 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a storage medium, a data recording and playback (4), and a control method and method thereof. The present invention further relates to a system for recording and reproducing data by a storage medium, and a file system and a control method thereof for failing to manage damaged location information, and [previous art], due to problems caused during manufacturing (for example, by traces and dust) Causes damage to the media and deterioration of features caused by repeated reading and writing): The storage medium usually has an area where data writing and reading cannot be performed. The technology for managing such data that cannot be written to and read from the area (damaged location information) has been used to store media and computer systems that require reliability.

The particular area used to store the corrupted location information resides in the storage medium, which typically replaces the damaged aerative region of the damaged block with an area that can be normally written and read. 'In some hard disk drives' certain optical disk media (for example, and storage media have specific damage replacement areas. In addition, even in the case of storage media that does not include corrupted location information, files containing corrupted alternative information can be included The system performs high-reliability read and write. For example, DVD-RW) storage media bad replacement area. However, in the case of optical disk media (example (which is different from DVD-RAM) does not include a specific loss

2156-9028-PF 5 200837736 According to the standard video recording format (vi (Je〇rec〇r (Jing f 〇rmat) (hereafter referred to as VR format) to write data into the DVD-RW example, because the slot system contains damage instead Information, so even if the damage is found in the storage media, the reading and writing can be performed correctly. It is worth noting that the file system supporting the VR format uses the Universal Disk Format version 2.0 mentioned in the STA (Universal Disk) F〇;rmat specification revision 2〇, UDF 2〇), its hyperlink is

Http 非 ji 非 非 非 非The organized re-learning DVD system published in International Standard Book No. 4 - 891〇〇-344-8 (Non-Patent Document 3)". Therefore, when a storage medium has a write error, the data can be changed without changing the application. The address management information is written to another address in the case of f month. For example, in the example of writing the 4th magnetic zone to the 4th block of the storage medium, 'When the writer device sends back the write When the error message is sent to the file system, the system writes the data of 16 magnetic regions to the 35th file of the damage replacement. The block 2 writes a write error even if it is written, and has stored W magnetic & The information written in the Block 4000 is still not required to be changed. The Patent Publication No. 2_44231 (Patent Document =: Technical Damage Management Technology, Medium Limit) Damage management is in the drive, so that the main system will not be affected The effect of the private order is replaced by an alternative to damage, etc. This technique includes the first management for damaged location management.

2156-9028-PF 6 200837736 % Area, user area, replacement area, and second management area, and the system area is defined in advance. However, when the application requests to read and must read the data of the 16 magnetic regions from the 400th block, the file system first searches for the damaged replacement resource, and the data in the right read address is registered. In the search for damaged alternative information, the system will attempt to read the data in the address. By this method, when the storage medium other than the file address management in the storage medium is damaged, the storage medium and the file system include a damage replacement function, information for storing the damaged location, and an area for performing the replacement processing. Therefore, once the damage replacement function is implemented, errors that occur in the storage medium will not be recognized by the system that is specialized in the slot system. However, if the data is written to a storage medium that does not include the damaged location information by a file system that does not include the replacement of the replacement information, the data cannot be protected even if an error occurs during reading, and the worst case will not be readable. Store media information. φ For example, in the example of a DVD-RW, a write operation can be performed by a video format for a read-only player (e.g., a DVD player) other than the VR format. The video format is used to perform write operations on the DVD-ROM that can be read by the DVD player. Therefore, when a user uses a DVD recorder to write audio and video and video data to a storage medium, the user usually uses the video format. However, since the video format uses the file system UDF 1. 02 (Universal Disk Format Specification Revision 02) mentioned in the 0STA (Non-Patent Document 2), the format does not include the UDF 2_ 〇 (Non, Patent Document 1) Similar damage to replacement information. When the information in each file is 2156-9028-PF 7 200837736, the starting logical address is the extension and 4 (four) Λ # , (4) the length of the group in the video format - the group address. W material (4) must have (4) continued bit delay j aspect 'in the case of _2. ° - the file can include multiple groups - even if the skip part of the damage is written during the file write, even if this is done, even if It can still be used in the generation of information, the management system in the storage media does not include damage for the K... "Baibei is still old. However, the video grid

丨 Group extension area, if an error occurs during writing, it is difficult to maintain the consistency of the marking system except for dividing the standard. In addition, there is a limit to the video format in the file system management and file storage management. It is necessary to set the slot system information, the video management slot group, and the single- or multiple video title rights group to the disk logical address = (see also, the video management group includes three Slot A, >, 疋 Λ 理 理 资讯 资讯 资讯 资讯 资讯 资讯 资讯 资讯 资讯 资讯 资讯 资讯 资讯 。 。 。 。 。 。 。 。 。 。 。 。 。 In many cases, the video tube is ignored: inside: object file. In addition, each video title file group includes a video title, a video file, a video title file file, and a video title information backup file as described above. Since the video format design is applicable to a DVD-ROM, it is usually beneficial to Pharaoh. ..., the number of damage to the storage media. Even if important, control, and right-click systems, information broadcasts, or audio-visual visuals are copied, the data cannot be read. The erroneous countermeasure is to make a copy of the backup message by creating a message slot in the video mode for 5 days >& Therefore, if audiovisual visual data occurs

2156-9028-PF 8 200837736 The error is one way is to use the video material to have the chronological related facts to repeat the previous information frame image data, and if the error occurs in the shadow material, the only way is to be quiet. Hide the error. Although the DVD-RW can usually be overwritten about 1 times, the area in which the file system information is written is the area where the number of overwrites in the storage medium becomes the largest, so even if the content data can be read normally, the storage is performed. The system information in the media is likely to become unreadable and writable. DVD-RW can be used to record two hours of standard quality video and audio content. In the initialization of the unused DVD-Μ and recording the two-hour content (in the example of the first content, the content in the storage medium is erased and the other two contents (the second content) are recorded again, and the file system information is executed four times. Overwrite, including initializing, writing the first content, erasing the first content, and writing the second content: due to performing two overwrites on the area of the recorded content, the execution is performed in the area where the standard information is recorded. The number of times of information overwriting is twice that of the recorded content area. Since the storage medium is usually used to record plural contents, the number of times of writing in the area where the information of the system information is recorded is several times the area of the recorded content, so the file is recorded. The area of system information will deteriorate faster than the area where the content is recorded.

It is possible to set the HD_-R large-capacity optical disc so that the system area called the extended management information area is set in the user data area to avoid the lack of the management information area or the S test area even if the user area has extra space. For the sake of this, the data of the writer cannot be executed. However, the 'k-like area is used to write the f-material to the disc media. & It is impossible to use this area because of the countermeasure against the error of the disc t (Japan 2156-9028-PF 9 200837736 0 0 5 - 3 5 3 2 4 No. 3 (Patent Document 3)). As described above, for the countermeasure against the damage of the storage medium, a storage medium including a damage replacement function (Japanese Patent Laid-Open Publication No. 2003-344231 (Patent Document 1) and No. 2004-5942 (Patent Document 2)) is used, and the damage replacement function is used. And the broadcast system of the file copy is the moxibustion test of the invention. / In addition, if the damage substitute is performed in the VR format disk medium, since writing can be performed while avoiding an error in the disk portion of the φ VR format, writing with high reliability can be performed. However, if the same media is reinitialized in the video format, the corrupted replacement information will be lost. This will make it impossible to perform the reading problem if the writing is performed on an area having low reliability. SUMMARY OF THE INVENTION Embodiments of the present invention provide a file system for reading and writing by using a storage medium: a system and a file system that cannot manage damaged location information, and the system is used to control methods and programs. In order to achieve the object of the present invention, the data read/= described in the embodiment of the present invention is a system for performing at least one of reading an information material from a storage medium and writing the information material to an e::! body.

The host control 11 20 transmits and receives the host system, the command and data host controller 20 of the system 1 Includes physical interface, Small Computer System Interface (SCSI)' IDE (Integral

Device Electronic), USB (Universal Serial Bus), IEEE1394, etc. The host controller 2 can be used as a designated electronic interface. The cpu 21 system controls the entire read/write device 2. The RAM 22 is used as a working memory. If the optical disk medium has corrupted replacement information (for example, MD-RAM), even if the RAM 12 is used to store part of the information required by the read/write device 2,

2156-9028-PF 13 200837736 RAM 22 will still store corrupted replacement information. The CPU 21 sets the detection circuit as a software for monitoring the item fetch/write information to the storage medium, and sets the damage management circuit to be caused by the information management read program from the loss m area of the test circuit. Damaged area = information. The CPU 21 is designed to use the damage management circuit to write damaged areas or resources to areas that are not primarily used to store corrupted location information. The photo sub-item write head 27 is used to write data to the storage medium 3 and read data written to the storage medium 3. The CPU 21 controls the read/write signal processor 25, the analog digit and the digital/analog converter 26, and the optical head (7) to read/write the logically designated position from the host system κ input to be damaged = stored according to the Bayer 21 system. The damage substitute in the RAM 22 is used to record the correct data (4) generation position, and thus read data or "alternative position" from the alternative position of the optical medium. 4% 疋 - - - - - - - - - - - - - If the system area of the storage medium does not include the recording area, the damage management circuit #趑贲μ 直 汛 汛 曰 曰 曰 # # 讯 讯 讯 # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # The system information order is used to manage the body.

The holding: the fine is stored in non-mainly used to store the damaged location information in the information area that does not include the damaged location, the initial initialization of the location information, and the file system that does not include the damaged location information, when the reinitialization is performed, the damaged officer The circuit can write the damaged location information as informational material (instead of the slot system:::) to the storage medium. The damaged location information includes the location of at least one of the physical segment number and the logical segment number. The damage management circuit can write the location of the damaged location information to the system area = it is not directly accessible and is not primarily used to store the damaged location information / / product and execute the writer. In addition, the damage management circuit can write the bit of the damaged location information in the user data area that can be read/written by the host computer 2 and store the damaged location information as a file. Furthermore, the damaged tube: the internal circuit can fix the position of the damaged location information in the user data area that the host system can read/write, and perform writing. The damage management circuit can write the damage location information to a block whose number is less than the start position of all user programs or the number is greater than the end position of all users and perform writing. In addition, when the storage medium that performs the recording by the file system that does not include the damaged location information is changed to

2156-9028-PF 15 200837736 When there is a file system that includes information on the location of the damage, the damage management circuit can be written as a bad location, so that it will not be read or written to the location including the damaged location information. And perform reinitialization.

If the location information stored in the file system matches the write location of the damaged location information, the damage management circuit can write the file system information behind the write location in the corrupted location and perform the write. In addition, if the file management information is only set together with a set of starting positions and file lengths, and if the write position in the damaged position m exists in the predetermined data size at the beginning of the file writer, the damage management circuit may The start sector number is set to be behind the write position in the damaged location information, and writing is performed. In the example where the file management information is set together with a set of starting positions and file lengths and records the audio/visual files requiring instant characteristics! If the writing position of the video/video file matches the writing position of the damaged location information, The host system 1 will not read or write the information material to the storage medium to request the information material to be written to the location of the storage medium 3 to be executed. When reading the material recorded on the storage medium, if the damaged location of the damaged location matches the reading position, the host system! The information will be read/written to the location of the storage medium 3 of the line by requesting that the poor data be written to the storage medium. When the item/write device reads the object file recorded in the storage medium 3, it has a backup file, and the damage bit in the right damage location exists in the record file. In the area, the illusion suit 2 will not read the read object, but will read the backup file. A detailed description will be given in the following embodiments. First, at the first

2156-9028-PF 16 200837736 The disk structure and the file structure of a DVD-RW (such as storage medium 3) will be described in detail. As shown in FIG. 2, the DVD-RW includes system areas 30 and 31. Sections 0 to 299 9Fh (h represents a hexadecimal number) from the system area 30 and a section 3000Oh or more from the user data area 31. The physical section number (PSN) = 30000h represents the logical sector number (LSN) = 〇h. The read/write device 2 has access to all physical sector number pSN regions to manage all the disks shown in Fig. 2. The host system i is a higher-order system that can only access segments of the user data area 31 with pSN = 3〇〇〇〇h or greater (i.e., segments with LSN = 0h or greater). Even if the DVD-RW media itself does not include a damage replacement function, manage the storage media. Recorded management data (Rec〇r(jing Management)

Data, RMD) and the damage status bit map area that manages the corrupted state are placed in the format 3 block 4 to field 13 as the main area for φ to store the defective position. However, this function is rarely used as non-mandatory in the standard. As shown in Fig. 2, the user data area 31 generally includes a file system, a free space 33, and a user data file %. In the example of applying the VR format to the VR format, the UDF2. is used as the file system and the file system of the Λ Λ 32. The file system information includes the capacity information 35 loss 襄曰 汛 36 and file information 3. In the area of the quantity information 35, when the file system is formatted, the management resources of the number of directories in the file, the number of files, and the storage medium are written.

2156-9028-PF 17 200837736 News 0 Damage replacement information 36 area is recorded when the storage media is damaged. In the VP format, the Damage Replacement Information 36 area includes a spare parts list showing the relationship between the damaged location and the alternate location, and the spare parts list typically stores 512 alternative beakers. The spare part area is set in the section from LSN = 14〇h to 21. Figure 3 shows a spare parts list for an embodiment of the damage replacement information 36. The spare part table of Fig. 3, 7F, is in a tabular format in which the logical area & LSN of the original position corresponds to the logical sector number lsn of the alternate position. If the replacement f-material area of the storage medium is not used, the spare part table of 帛3_ records FFFFFFFFh as the logical segment number LSN of the original position, and if the recorded data position is replaced due to the damaged relationship, the logical position of the original position The number LSN is recorded as the logical segment number of the alternate location. Figure 3 will provide a detailed description of the first damage. Figure 3 shows the location where the original location is the logical sector number LSN = 4500h, which is corrupted in the storage medium, replacing the poor memory write position with the logical sector number LSN = 14〇h (spare part table). The area of the file information 37 is the name of the directory to be written to the storage medium when the data is created, as well as the file name, file attribute, starting position of the file, and file length information. In the Universal Disk Format (Universal DiskF() nnat, UDF), the starting position of the archive information is managed by the logical block number lbn which is the effective capacity space. In the VR format, the path and the dvd_dtav directory are usually used as directory names. Figure 3 also shows that the three files following the DVD_RTAV directory include the video manager information file.

2156-9028-PF 18 200837736 (VR_MANGR. IF0) 38, video data file (VR_M〇VIE VR〇) 39 and video manager information backup file (VR_MANGR. βυρ) 4〇. A file in UDF 2.0 can store multiple extensions. Referring to Figure 3, VR_M0VIE. (4) 39 has three extended audit files 仏 42 and 43. When the title of the content in the media is sequentially read, the first extension information 4 and the second extension information 42 and the third extension information 43 are also sequentially read. On the other hand, when the first extension information 4, the second extension information 42 and the third extension information 43 are written, it is not necessary to write in accordance with the order of the setting extension 41 and the extension m extension 43 in ascending order. 〃 Video Manager Information Archive 38 Content displayed in the media The location of the media is recorded in the slot by offset value (same as for broadcasting in the computer: in VR mode, the application does not need to identify the storage medium) The I° section encodes the LSN to perform the access. In addition, even if the storage medium is bad, the file system will absorb the damage, so that the application layer == is corrupted. In addition, in the VR mode, even in the record complex, the κ column The number of slots in the storage medium cannot be changed. The formula: I will show in the figure 4 that when using the video mode, the application: the preparation configuration. The user data area 31 includes the third figure.俨荦糸 资讯 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 Includes corrupted replacement information 36 (included in (4) 2 view = includes the title file group used to manage the storage media, and the video title corresponding to the individual content

2156-9028-PF 200837736 File group. The user profile 34 shown in FIG. 4 stores a video manager profile for managing the title in the storage medium and the first video title 对应 and the video title 52 corresponding to the two contents.

As shown in Figure 4, the video manager file 5 files includes three files, that is, the video manager information file (VIDE〇-TS IF〇) 53 and the video manager data file (VIDEO-TS.V0B) 54 and Video Manager Information Backup File (VIDE0JS.BUP) 55. The video manager information file 53 and the video manager information backup file 55 store the same content. In the video mode, when recording a title, at least four files are created, that is, the video title information file (VTS-OH IF〇) 56, the video title data slot (VTS-02-U0B) 57, the video title data Slot; (VTS-02-2. V0B) 58 and video title information backup file (VTS-02-〇·ΒυΡ) 59. In addition, since the upper limit of the parent-video files 57 and 58 in the video format is about 1 GB in Anba, it is necessary to warn the file as a number of slots. A plan (4) can include up to nine video archives, so up to 9GB can be recorded. Then ^ red, private, and the right video file title includes the number of video title data files, aligned in order.匕: (4) μ according to the recording time in the video mode of the video manager information 浐安^书贝0Κ file 53 and the video title, ^木54 does not indicate the video title file slaughter in the low-minded office ^ ^ currently read h (four) (four) offset position 'There is its storage and the LSN offset value of the file location. Therefore, the information obtained by the video manager is replaced by the file system backup file 55, the field file 53 or the video manager information needs the file system. After the &&;; start position, the application format can be set to play without content. When getting the video mode

2156-9028-PF 20 200837736 After the information file start position, the DVD recorder and player usually do not need to access the recording device control layer 62 directly through the file system layer 61. In addition, since the video mode does not include the damaged substitute information (different from the ... mode), the file corresponding to the write cannot be read when the storage medium is damaged. It is important to note that if damage occurs in the storage medium, it may cause problems in the system operation of the video mode that the damaged location information cannot be managed. For example, if the record file system information 32, the video manager information file 53, and the area of the video title information (4) 56 requiring reliability are damaged and cannot be recorded in the storage medium, the read/write transmission error is responsive to the host system 1. Since the read/write device 2 attempts to write data to the storage medium until the error response is transmitted to the host system 1, it takes several minutes to several tens of minutes of response time, and moreover, due to repeated writing to the damaged area. Causes an expansion of the damaged area. As described above, the embodiment of the present invention prevents the write from occurring by destroying the location information in the storage medium (even if the storage medium or the slot system does not include the damaged location information). To shorten the system back to the shore and allow normal reading of the content recorded on the storage medium. Figure 5 shows the data input/軏 configuration diagram in the data read/write system.

The file system layer 61 converts the logical phase of the file into a logical segment of the storage medium (10) according to the file on/off processing program and the request from the application layer 60 (4) file request or the file writer, and converts according to the logical segment (10). The data is rotated out to the read/write device control layer 62. In response to the data read request from the file system layer 61, the read/write = set (four) layer 62 generates a data input/output control signal corresponding to the electronic I/F format, and outputs a data read request to the generated signal according to the generated signal. The control layer 6 3 in the read/write device. According to the data read request from the read/write device control layer 62, the control layer 63 in the read/write device converts the logical sector number lsn of the storage medium into the physical sector number PSN, and reads the psn region in the storage medium. The data is output to the read/write device control 62. Thereafter, by reading: the data from the lower layer (the read/write device control layer 62 and the file system layer (1) can also perform data reading in the file system layer 61 and the application layer 6〇. In an embodiment of the medium (as in the example of reading data), the read/write device 2 in the control host system i pairs each of the higher order application layer 60 to the lower order control layer 63 in the read/write device. The data write request performs the necessary conversion, thus performing a data=input request for the lower level. ..... In the embodiment, an example of using DVD_RAM as a storage medium to read data is considered. Due to the storage of DVD_RAM There is corrupted replacement information in the media, so when the read/write device control layer 62 requests the logical segment

Therefore, the host in the higher layer:: "The data in the device can be read to damage the data.,,,, and not to identify the same. In the embodiment of writing data, ^ segment number PSN The physical area of the M 1 right conversion has been registered. „ The main volume is in the smashing replacement information, and the area of the replacement physical segment number PSN is written into the physical segment number PSNWS of the Gobe. If the converted material is written to the storage body t, the conversion::: know (four) is the capital... the area of the physical segment number PSN converted in the asset. In the case of 1 2: 'If the data cannot be written to the storage medium, the read/write device inner layer 63 writes the poor material into the damaged substitute information. The unused substitute 2: the converted physical segment number PSN region . The corrupted replacement information is updated when a successful material is written. After the update, even if the read/write request is input from the read/write device control layer 62 to the area where the damaged physical sector number is generated, it is read from the area registered in the damaged substitute information instead of the physical sector number. Or write data. ^ In the case of DVD-RW for VR format, the spare part table is stored in the file system, first. Therefore, in converting the logically related position of the file into the logical segment number LSN, if the information of the converted logical segment number LSN exists in the spare part table, the reading position is changed to the same by using the spare part table. Replace the position of the logical segment number LSN, thus transmitting a data read request to read /

The device control layer 62 is written. Therefore, the application layer 6 can read the data without identifying the damage in the storage medium. 2156-9028-PF 23 200837736 In Fig. 6, it will be explained that the storage medium described in each method of the present invention is in the first place, and whether the file includes location information or damaged replacement information (step S100) is determined. Currently stored in the format of the format, if the file system includes the location information, then the virtual search you #. 】 processing the private order to the damaged location information reading and registration program sun), and if the slot system does not include damage For the location information, the processing proceeds to the initial (four) order of the damaged location (step S1 0 2 ). In the damaged location information reading and registration process (step si〇. The damaged replacement information is read from the storage medium and registered in the memory (10) 22) 'and the processing proceeds to the initialization end judgment program "I〇 3) • In the damage location initialization procedure (step 2), since the damaged location information does not exist in the storage medium, the memory (RAM 22) for damaging the location information is initialized, and the processing procedure continues to The initialization end determination program (step S1 〇 3). The loop processing is executed in the processing program from the initialization end determination program (step S103) to the write error program (step S109) until the aforementioned initialization program is executed. When the program is initialized, the damaged location information is written into the storage medium and the initialization process is terminated. The value indicates that if the result of the end of the determination process (step S1〇3) is "No", then the next step is required. The data is initialized (step S1 04), it is judged that the logical segment number LSN is written, and the processing program proceeds to the damaged position determining program (step Step S1 〇 5). In the damaged position judgment program (step S1 05), the registered damage will be

2156-9028-PF 24 200837736 % The position information is compared with the write logical segment number LSN. If the write logical segment number LSN is registered in the damaged location, the processing proceeds to the LSN reset procedure (step si〇 6). If the write logical sector number LSN is not registered in the damaged location information, the processing proceeds to the initialization data writing process (step si〇8). In the LSN reset procedure (step S106), the write section (four) LSN is updated by adding an eiTor check and correct (ECC) section to the write section number LSN, and thus enabling The data of the area not having the damage is written, and then the processing proceeds to the damage position judging process (step S107). If the information of the ID zone # and the number UN is included in the initialization data of the damaged position determination program (step S107), the recalculation is performed by the new logical sector number LSN, and then the processing proceeds to the damaged position. The judgment program (step S105). In the initialization data writing program (step S1 〇 8), the initialization data is implicitly entered into the area of the determined logical sector number LSN, and then the processing program proceeds to the write error determination program (step sl1). It is worth noting that the unit for writing data is usually an ECC unit. In the write error judging program (step sl9), it is judged that there is an error in the write data, and if there is, the processing program proceeds to the corrupted position registration private sequence (step S1). If there is an error in the middle of the written data, the processing proceeds to the initialization end judging process (step S103), and the initialization process is continued. In the bad location registration procedure (step 0), a write error occurred.

2156-9028-PF 25 200837736 The logical sector number LSN is registered in the damaged location information, and then the processing proceeds to the damaged location determination procedure (step 〇5. Although the previous UDF 2. 0 slot system does not include the first 6 _ (4) S105, S106, S107 and S111 'However, the UDF 2 file system has a damage replacement function including processing steps S105, S106 and sill (as in the embodiment of the invention). The alternative program for the damaged location is included in the file of the F2 file. The system towel' is therefore stored despite the logical segment number (10) of the damaged bit 4:

The conversion will still be performed in the spare part table in the initialization data, so there is no need to change the file system information. The file system of the embodiment of the present invention does not include the damage replacement function, and therefore the logical sector number LSN information in the initialization data must be set by the processing procedure of step S107. When the system that does not include the damaged location debt test function reads and records the storage medium of the file system according to the embodiment of the present invention, the information is: the content is set at the readable position and the damaged location is not required. News. Because ’ ’ even in the system using the previous case, the data in the storage medium can be read as long as the version of the file system is compatible. This is the best result. In addition, if a corrupted location of the storage medium obtains a write request or a read request, the read/write device accesses the storage medium multiple times until the reading or writing is completed, thus requiring a relatively long reaction time. In contrast, in the embodiment of the present invention, if the damaged location registration information is used, the device accesses the corrupted location by the & method, and thus the embodiment of the present invention has the advantage of high speed processing. In addition, even if the embodiment of the present invention has explained an error occurring at the time of writing, if the storage medium is in the writable state, and if the reading is subsequently obtained,

2156-9028-PF 26 200837736 Find (even for errors that occur when reading the same handler) the handler can be executed at high speed. Figure 7 shows the configuration of corrupted location information written to the storage medium. In Figure 7, the characters of the four-byte group are listed and recorded in the bit position. When the damaged location information stored in the storage medium is read, the information provided by the serial array is used to determine whether the data is valid. Referring to Figure 7, the four-byte cyclic positive code (CRC) is stored at the bit position 4胄. The crc system is combined with the # s recorded in the bit position 8 (slot number 8 of the bad position) to determine whether the error occurred in the read data. In Figure 7, the number of registered damage location information is stored in bits 1, 4, and 4, and this value can be used to determine the damage location in the storage medium. If the number of the damaged location exceeds the above value, it may be possible to pass a fact to the user using I u ^ , , , or the user, that is, even if the user orders to perform initialization, the normal writer operation cannot be performed. This may result in a storage medium that cannot be used to write important two-person status. In Fig. 7, the update time for the damaged location information in the storage medium is stored in the bit location 16. Generally speaking, it is stored in the Tan dynasty system. After that, the % interim news is stored, so that this is the latest k between the storage media. Therefore, it is necessary to judge the damage location information. The time information of the catalog, the time information of the file, and the time information of the internal damage location information of the filing system information to confirm the damaged location. Corruption=Time information is the latest time information in the storage medium. In Figure 7, the location of the bad (such as the logical section number 匕 (8)

2156-9028-PF 27 >>200837736 The four bytes after bit position 2 4 . According to the formula (s - 2 $ ) / 4, the position of the bit of the nth damaged position can be obtained. Only the damaged position of the embodiment of the invention is stored in the ECC unit, and the same effect can be achieved by storing the damaged starting position and the damaged Ecc block together with the segment number as the extension information. It is worth noting that in the case of 2 mobile media (such as optical disk media), there may be scratches or dust (such as hair) around the surface of the media, so that the data cannot be continuously written in the area. . Because &, it is also possible to perform management effectively by extending the information. Three methods of writing damaged location information to the storage medium will be described in the following embodiments. The first method is to write information to the system area of the storage medium. The Recording Management Data (RMD) area for managing the storage state of the storage medium, and the damaged status bit map area for managing the corrupted state are stored in the format mainly used to store the damaged location information. Field 4 to Block 13. In the embodiment of the present invention, the damaged location information is written into the format 3 block 2 of the RMD area to allow the user to write data. Since the damaged status bit map is not installed in each optical disk writer, accurate location information cannot be obtained. The second method is to write information to the location of the logical sector number LSN determined in the user profile area 31. As in the logical section (4) (10) position, both areas can be used. That is, the video manager 37 set in the file information 37 of Fig. 4 and the top of the user profile file of Fig. 4

2156-9028-PF 28 200837736 The area between the files 37 (the first-damaged location information configuration area), and the area between the last title of the storage medium (the second loss location information configuration area),县楚_ _ 疋 — — 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 最后Can be used to write information. .,

In the view format, one storage medium can record 99 titles, so the area for recording the file information 37 of the titles must be reserved before the user's bedding file 34. The logical sector encoding LSI of the archive information area 37 must be smaller than the logical sector encoding lsn of the user data standard. Since a disk rarely records a title of 99, there is usually unused free space between the file information 37 and the user profile 34. Since the start logical segment number LSN of the user profile 34 is not defined in the video format, the region that can be used to record the damaged location information is fixed to the free space towel as the first-damage location information configuration region. In this example, the file system is taken as an example. 'Because the area of the logical segment number LSN of the damaged location information is the un-materialized area, the example of performing the initialization in the case of not including the damaged location information management function will be damaged. The location information is deleted, but no logical inconsistency occurs in the example of only performing the reading: in addition, even in the case of the additional writing storage medium, the storage medium is initialized by the method of the embodiment of the present invention, and cannot be managed. In the system for damaging the location information, since the damaged location information exists between the file information Μ and the video management information file 53, the area cannot be overwritten, so that no problem occurs during the recording process. For the data management system that manages the damage location information, the system writes the system to perform additional writes.

2156-9028-PF 29 200837736 The damage information, the damage location information will not be updated, so there is still a problem of data logging system and system management. b A second corrupted location information configuration area is located near the last logical sector number LSN of the last video header information backup file, and the location is a logical sector number [SN] starting with the ECC unit. Even if the second damaged location information configuration area is added every time the video title is added, the latest damaged location information can be written by the new damaged bit after the writer finishes.

The information is stored in the storage medium. By writing the damaged location information into the two areas, that is, the first damaged location information configuration area and the second damaged location information configuration area $, the data in the storage medium can be repeated to improve reliability. The second method is to write information into a storage medium as a general file. In the video format example, the information file location indicated by the information file is offset from the logical segment number LSN position of the information file in the storage medium. The area in which the file can be set is limited. In Figure 4, four areas can be obtained, that is, the area before the video manager information file 53, the area between the video manager information backup file 55 and the first video title information file, and the first video title information backup broadcast case. The area between the second video title information file 56 and the area behind the second view=title tribute backup file 59. It is worth noting that the above data is not used in data disks that do not use the video format but use UDF1.〇2. , a 4 Combine these configuration areas for the damage location 35 to improve the reliability of the information.

2156-9028-PF 30 200837736 In the figure of the 8th, it will be explained that the write error occurs when the t-writer file is written = the position management method (hereinafter referred to as the LSN sliding method assumes that the broadcast system is UDF U2' and assumes that the writing is performed in the video mode. S200) First, set the logical section (4) (4) of the file to be written (the step determines whether the directory file can change the logical sector number LSN according to the set logical sector number LSN (step S2Q1). It is worth noting that If the file is a video manager information file or a video title information file or a backup file of the above two, it is determined that the file is executable (four) sliding broadcast 'the processing program continues to the damaged position determination program ( Step S204). If the file is a video file or a video title data file, it is determined that the file is a file that cannot perform the LSN sliding, and the processing program is continued to the data writing process (step S2〇2) In the data writing program (step S2〇2), the data is written into the storage medium, and then it is judged whether or not an error occurs in the process of writing the data to the storage medium (step S203). In the write error judging program (step S2〇3), if an error occurs when data is written to the storage medium, the Z program will not end normally. If no error occurs during the writing, the processing proceeds to Updating the file information (step S209). In the damaged position determination program (step S2〇4), the registered damaged position information and the written logical segment number LSN are compared, if the logical segment number is written When the LSN has been registered in the damaged location information, the processing proceeds to the LSN reset procedure (step S2〇5), whereas the processing proceeds to the data write procedure (step S2 〇6).

2156-9028-PF 31 200837736 In the LSN reset procedure (step S2〇5), the Εα segment is appended to the written logical segment number LSN to write to the non-corrupted region, and the logical segment number LSN is updated, The false report and the follow-up #^ / 牧木慝理耘 坛 进行 progress to the damage position determination program (step S204). In the data writer program (step S2G6), data writing is performed, and the private sequence is processed, and ..k4 proceeds to the write error judging program (step $2〇7).

In the write error determination program (step S207), if it is determined that there is a write error ', the processing program proceeds to the damaged location registration procedure (step S208), whereas the processing proceeds to the file information update procedure (step is corrupted) In the location registration procedure (step S208), the logical sector number LSN, which cannot write the damaged location information, is registered in the damaged location information, and the number of damaged location information is updated. 'Next processing proceeds to the LSN reset procedure (step S2〇5) In the write error judging program (step S207), if it is determined that there is no write error and the writer program is normally completed, it can be updated according to the logical area & The slot information (step S2〇9), and ends the writer sequence. The difference between the present and the prior art is that the UDF 1·〇2 does not have the function of officially damaging the location information, so the file write sequence Only steps = 200 S203, S204, and S209 are performed. Therefore, if an error occurs during writing, <p causes the application layer to include a sequence by adding the Ecc segment to the write (10):: Processing The program, however, still can't manage the occurrence of the error, and by storing the write relationship to the damaged location while writing

2156-9028-PF 32 200837736 In addition, in the example using UDF1_02, even if the file system has the functions of steps S204, S205 and S208, the file system cannot judge whether the logical sector number LSN in step S201 can perform sliding. If the operation cannot be performed on the logical segment number LSN group in step S200, it is not only necessary to update the damaged replacement information, but also to update the damaged location information of the slot itself and the location information.

The method of writing the rights requiring immediate characteristics (e.g., video data broadcast (hereinafter referred to as LSN omission)) will be described in detail in FIG. First, the setting data is written to the LSN (step S300), and the processing procedure is continued to the damaged position determining program (step S3〇1). In the damaged position judging program (step S301), the logical segment number LSN to be registered for the damaged location information and the write is compared, and if the logical segment number LSN written is registered in the damaged location information, the writing cannot be performed. Writer of logical section number LSN, and the handler will terminate. If the written logical sector number LSN is not registered in the damaged location information, the processing proceeds to the data writing process (step S3〇2). In the material writing program (step S3〇2), the material is written in the area of the logical sector number LSN to be written, and the processing proceeds to the writing error judging program (step S303).曰, ^ In the write error judging program (step S303), it is judged that the written data has an error. If there is a write error in the right shell, the processing proceeds to the damaged location registration procedure (step S3G4), otherwise the processing is terminated. The embodiment of the present invention includes steps S 3 01 and S 3 0 4, which are

2156-9028-PF 33 200837736 The prior art _h0" is different. The damage position judgment of the example S301 does not include the step up to the _% order, even if the logical section number L, 'the data has been stored in the media. ,... The release of the £ domain write command still cannot be written to Beca. In the example of the sample, the reading/inquiring question is 廿 、 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Generally come: to include the memory for the approx. +, eve, and the recorder, the memory of the video and the audio and video, so it must be interrupted. The write procedure of the content must be reversed. 'The writer method according to the embodiment of the present invention will not issue the nesting instruction to the logical sector number that has been registered in the corrupted bit. LSN's trick: This reduces the chances of interrupting writer operations as in the prior art. , the right is not registered in the damaged position 詈: The other part of the logical section number LSN of the exhibition of the singer's exhibition is the same as the other information k ' even if the content is currently written, ^ „ this..., 'friends like technology first lend = The damaged location registration procedure of step (10) is normally performed by writing: ., ', after the registration sequence is registered in the damaged location information, so that the probability of the incoming operation is lowered. The horse is written using the write system of the embodiment of the present invention. In the example of the content, the data will not be written in the area recorded in the logical section number in the damaged location information. Since this example is the same as the writing method in the prior art, the decoding error of the AV decoder does not occur even when reading. Any problem will be caused. The reading method using the damaged position information will be explained in Fig. 10. The method shown in Fig. 10 is not to skip the method 'but to read by the °LSN skip method The method of entering the data file. First, the logical section number LSN of the reading is set (step S400), and the processing program of 2156-9028-PF 34 200837736 proceeds to the damaged position determining program (step S4〇丨). Bit In the judgment program (step S401), the registered damaged position information is compared with the read logical segment number LSN. If the read logical segment number LSN is registered in the damaged position information, the processing program continues. To the data reset program (step S402). If the read logical sector edit LSN is not registered in the damaged location information, the processing proceeds to the data read program (step S403).

In the material resetting process (step S402), the material reading command is not transmitted to the reading device 2, but only the requested number of bytes (for example, Q 〇h) in the fixed material is transmitted, and the processing is terminated. . In the material reading program (step S403), the data is read, and the processing proceeds to the reading error judging program (step S4〇4). In the reading error judging program (step S404), it is judged whether or not there is an error in the read data. If there is no error in the read data, the processing sequence ends normally, otherwise the processing program ends abnormally. The embodiment of the present invention is different from the prior art using MN 1.02 because the embodiment of the present invention includes the two steps of steps S401 and S402. : Generally speaking, when the read/write device 2 receives the read request, the read/write device (3) attempts to read multiple times (even if there is an error in the storage medium), so it is necessary to: the reaction time of the heart. However, by using the reading of the embodiment of the present invention, the logical section number LSN of the seek is located at the location of the damage.曰, 至硕/写衣, this can shorten the reverse. In addition, replace the logical segment number of the damaged position with 〇 Oh.

2156-9028-PF 35 200837736 In the example of the LSN data, even if the data reading cannot be performed in the reading method of the related art', since the file for transmitting the read request requires an instant characteristic, by using the AV decoder The error insertion function allows the dvd recorder and the like to achieve the same reading effect. " The 11th ffi shows the file reading method when storing two files with the same contents in (4) and having corruption in the main file. First, 'set the logical sector number LSN of the file to be read (step 5500), and the processing proceeds to the damaged position determining program (step 5501). ° The damaged position is registered in the damaged position determining program (S501). The information and the logical segment number LSN of the file to be read are compared. If the logical sector number LSN of the upcoming broadcast is already registered in the damaged location information, the processing proceeds to the backup archive judging process (step S502). If the logical sector number (4) of the file to be read is not registered in the damaged location information, the processing proceeds to the broadcast reading step S504). In the backup file determination program command (step S5〇2), it is determined whether the file in step S500 has a backup file, and if so, the processing program is relayed to the read standard reset program (step S5G3); Then, the process proceeds to the file reading process (step s5〇4). In the item resetting program (step S5〇3), the logical sector number LSN is set, and the processing proceeds to = (step S504). The mussels are in the broadcast reading program (step S5〇). 4) reading the broadcast, and the process

2156-9028-PF 36 200837736 The sequence continues to the read error determination procedure (step s5〇5). Set group t: take the error judgment program (step S505) to perform 'two' on the read data. If there is an error in the read data, it will not stop normally at the autumn order. Otherwise, if the read data does not have If the error occurs, the handler will be aborted normally. This method is different from the reading method using UDF 0.02 in the prior art, except that the embodiment of the present invention includes the steps MM, "Μ ^ and S503 in two steps. In other words, in the previous In the technology, when executing: taking the relevant slot case but unable to read the right material, if there is a wounded broadcast case in the storage medium, it is expected to perform a read operation on the backup broadcast case, and in the previous technique, the damaged location information is not Included in the file system, and will attempt to perform several read operations on the storage medium. Because &, it takes tens of seconds or even minutes of reaction time in the reading process. On the other hand, the reading method according to the present invention If there is damage in the object file, the backup file storing the same information will be read. Therefore, the requested file can be read at a higher speed than the prior art. However, it is straightforward to note that if When a read error also occurs in the backup file, the same read time as the prior art must be spent. As described above, the data recording system including the damaged location management information including the embodiment of the present invention is used. When the storage medium is damaged, it has the possibility of maintaining the reliability of the data. In addition, even if the storage medium itself does not include the damage replacement function and the slot system does not have the damage replacement function, the system can perform the high-speed operation of the parent. Even if the storage medium Includes damage replacement features or file system including damage 2156-9028-PF 37 200837736

An alternative function, the damage location management of the embodiment of the present invention - in other words, the number of replacements in the storage medium or the broadcast system is limited because the number of replacements is limited. Even in such a storage medium or slot system, the y:: yoke example has a remarkable effect 'even if other damage occurs, the position management can be performed by the damaged location management information of the present embodiment. Although the above is disclosed in the preferred embodiment, it is not intended to limit the scope of the invention, and anyone skilled in the art can make a few changes and refinements without departing from the invention: The invention shall be subject to the scope defined by the scope of patents. The body or:: The embodiment may perform data reading by using a storage medium that cannot manage location information.
