Abstract

A method of overwriting data in a write-once information storage medium and a data recording and/or reproducing apparatus therefor. In the data overwriting method, a command to overwrite new data in a first area of the write-once information storage medium where data has already been recorded is issued. Then, the first area is considered as a defective area, and the new data is recorded in a second area. Thereafter, updated defect management information, including information about the locations of the first and second areas, is recorded in the write-once information storage medium. Accordingly, overwriting can be performed in write-once information storage media, which is incapable of physical overwriting, by using a logical overwriting technique. Thus, data recorded in the write-once information storage medium may be changed or updated.

And with the drawings, for details The following is a detailed description of the embodiments of the present invention, which are illustrated in the accompanying drawings, in which BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a structure of a write once disc information storage medium 1 having a single recording layer according to an embodiment of the present invention. Referring to FIG. 1, the storage medium 100 includes an import. A lead-in zone 120, a data area 130, and a lead-out zone 140 for recording a temporary disc defect structure (TDDS) and a space bit map (SBM). The area 121 of the two is located in the lead-in area 120. The other area 122 for recording the temporary defect list (TDFL) is also located in the lead-in area 120. The spare area allocated to manage temporary disc defects and 2 (respectively 133 And 134 are respectively located at the head and the tail of the data area 130 and have a predetermined size. 13379pifl.doc 9 1271713 Alternatively, to record the temporary disc defect structure (TDDS) and the vacancy map (SBM) The area 121 may be located in at least one of the lead-out area M and the data area 13. The temporary disc defect management, the spare area allocated for temporary disc defect management, and the space bit map (SBM) will now be described in detail. Management Table 2 is an operation 'where the defect is generated in the user's poor material recorded in the user data area 135, the operation will record the new user data corresponding to the defective user data to compensate for the Missing data due to defects. Disc deficiencies management is broadly classified into disc defect management using linear replacement technology or disc defect management using sUpping replacement technology. For the linear replacement technique, if a defect is created in the user data area of the data area, the defective area will be replaced by a non-defective spare area located in the data area. For the slip replacement technique, the defective area will be skipped (ie, not used) and replaced with a non-defective area. The linear replacement technique and the slip replacement technique described above have been generally applied to an information storage medium capable of recording data several times by a random access method, such as a DVD-RAM/RW, as shown in FIG. 1, according to an embodiment of the present invention. The write information storage medium 100 also configures the spare areas 1 and 2 (133, 134) in the data area 130 to perform defect management using the linear replacement technique. When the above-described information storage medium is initialized for use, the spare areas 1 and 2 (133, 134) of the data area 13 will be configured in accordance with a data recording and/or reproducing apparatus or a host command. 13379pifl.doc 10 1271713 When loading information storage media in a data recording and/or reproducing device, the data recording and/or reproducing device will read the information stored in the import and/or export area and determine how to manage the media and How to record data in this media or reproduce data from this media. As the amount of corruption recorded in the import and/or export areas increases, the time required to prepare to record or reproduce the data after loading the information storage medium will also increase. In order to reduce the time required to prepare for recording and/or reproducing data, the information storage medium 100 is written once in the figure to use temporary management data, including temporary disc defect (TDDS) and temporary defect list (TDFL). ). Temporary Disc Defect Structure (TDDS) may include temporary disc defect structure (TDDSm symbol, update counter, last temporary defect table (TDFL) record position related information, final disc and disc machine information. Please replace the defect cluster (dus (4) spare area information, and other similar information. Temporary defect table (TDFL) may include temporary defect table (TDFL) identification symbol, update counter, defect factor, number of defect factors, And other similar information. The above defect factors include state data, location correlation of defect clusters, and location-related data of alternative clusters. The above state data may indicate alternative data, types of defect clusters, and other similar data. This may include clusters of defects that need not be replaced, clusters that may be defective = other similar information. 'Different 1 writes once the information storage medium 100 stores a space bitmap (SBM) as the "record status" data, which represents Whether the data has been recorded at 13379pifl.doc 11 Ϊ271713 The cluster unit on the storage medium. The space bitmap (SBm) is formed by assigning the bit value to the occupied cluster and assigning the bit value 1 to the unoccupied cluster. Therefore, the data recording and/or reproducing device borrows By referring to the last updated space bit map (SBM), it is possible to quickly check the recording state of the information storage medium 100 written in FIG. 1, thereby increasing the use efficiency of the medium. Although the information storage medium 100 is written once in FIG. The space bit map (SBM) is stored in a cluster together with the temporary disc defect structure (TDDS). However, the present invention is not limited to this embodiment because the above-described space bit map (SBM) indicates whether or not data has been recorded for writing. One cluster of information storage medium 100, so after all the other materials including the user data are recorded, the above-mentioned space bitmap (SBM) must be updated. Figure 2 shows a single type according to another embodiment of the present invention. The structure of the recording layer to be written once to the information storage medium 200. Referring to Fig. 2, the storage medium 200 includes a lead-in area 220, a data area 230, and a lead-out area 240. A temp〇rary defect management area (TDMA) 221 and a vacant bitmap (SBM) area 222 are separately located in the lead area 220. The spare areas j and 2 for the temporary disc defect are used (respectively and 234 respectively) They are respectively located at the head and the tail of the data area 23〇 and have a predetermined size, and sandwich the user data area 235.

The fourth drawing refers to a write once recording medium (for example, 1 〇〇, 2 〇〇) having a single recording layer, and the 4B drawing refers to writing having a double recording layer (that is, the first and second recording layers). Recorded media once (for example, 300). Referring to Figures 4A and 4B, in the first recording layer (or single recording layer), in accordance with the direction from the inner edge 402 of the recording medium (1(8), 2〇〇, 3〇〇) to the outer edge 403 thereof 401 uses a data area other than the 13 13379pifl.doc 1271713 spare area, that is, the user data area (135, 235, 333). In the second recording layer, the user profile area 365 will be used in accordance with the direction 405 from the outer edge 4〇3 of the recording medium 300 to the inner edge 402 thereof. As shown in Fig. 4A, the spare area 2 (134, 234, 332) will be used in a direction 406 opposite to the recording direction 401 for easy extension, i.e., according to the outer edge 403 from the recording medium (1, 200, 300) to the inner edge thereof. Direction of 402. As shown in Fig. 4B, the spare area 4 (364) will be used in accordance with the direction 4 from the inner edge 402 of the recording medium 3 to its outer edge 403 (Τ7) for easy extension. As described below, in order to utilize the present invention Defect management to perform logical overwriting, so writing an information storage medium in accordance with the present invention may require a wider spare area than conventional information storage media. Therefore, it is best (but necessary) to initialize the information storage medium. Or during the use of the information body, in order to be able to extend the spare area during use of the above-mentioned data storage medium, it is preferable (but not necessary) to record data in the opposite direction to the user data record. The area and the first map are shown in Fig. 4. The method of the tribute storage medium according to the two embodiments of the present invention will now be described with reference to the information shown in Fig. 3 and Fig. 3(3).

Recording and / or reproducing data on the information storage medium 30 写入 once written, n52〇 The defect management is performed by using the temporary k-defective job (TDMA) of the write-time information storage medium 3 (8). The controller 520 follows a post-write verification material ^Γαί^Γ_1η§) method, which is in a predetermined unit Recording assets = After entering the poor storage storage ship 300, the recorded information will be verified. (The predetermined unit records the information of the messenger and the verification record to identify the defect data. The controller 520 generates the # Temporary Defect Table (TDFL) for the area in which the defect data found during verification is stored And a temporary disc defect structure (TDDS). The controller 520 stores the temporary defect list (TDFL) and the temporary disc defect structure (TDDS) in the memory, and collects a predetermined number of temporary defect tables (TDFL) and temporarily Disc Defect Structure (TDDS), and the collected Temporary Defects (TDFL) and Temporary Disc Defect Structure (TDDS) are written to the Temporary Defect Management Area (TDMA) 321 located in the write storage medium 300. The above-mentioned data recording and/or reproducing apparatus 5 of the data recording and/or reproducing apparatus 5 of FIG. 5 will be described in more detail by using the latest (four) system as an example of the data to be overwritten. 13379pifl.doc 1271713 The recording and/or reproducing device updates the above-mentioned write-time information storage medium 4=糸冼 for the write-time information store. In other words, the data record and / or regenerative data and the storage of the latest slot == "Storage Media Logical Address' and then from the Recording Map (S_) ::疋:Ϊ Address The corresponding physical address has been recorded. ^图=ΒΜ) can be read out from the above-mentioned write medium by the recorder/reader 5ig and stored in the memory 53. If it is determined that the entity address has recorded data, then the above physical address === area and then 'record the latest _ (10) λ Γ data record and / or regenerative equipment 1 500 does not use this vacancy map _ material record and / Or the regenerative device may determine the defective area by writing the post-test 3 words - the area of the recorded data, and then recording the new groove (4), which is unified in the above area. Thereafter, the record - the latest temporary piece, structure ( TDDS) and - The latest temporary defect list (TDFL) is in the Temporary Defect Management Area (TDMA) 321 . The younger brother = Fig. 6D shows a method of overwriting the latest slot system for writing to the human memory storage medium. In the method described with reference to FIGS. 6A to 6β, the first and second spare areas 331 and 332 will be represented by (4), SA2 and located in the data area (for example, the head and the tail of the data area. The area in which the file system is stored is located at the head of the user data area 333. 16 13379pifl.doc 1271713 In Figure 6A, the initial file system FS# is recorded in an area from the head of the user data area 333 to a predetermined location. In the 6th figure, the initial slot system FS# of the user's cultivating area 333 will record the first user's capital = 'weave the defect management according to the above-described embodiment of the present invention. The generated 帛_most_contact is recorded in the second spare area SA2. In FIG. 6C, the first user data 6〇1 immediately following the user data area will record the second user 〇6〇2, Then immediately following the first-latest (four) system Fs#1 will record the second latest broadcast system FM2. In the sixth DD, immediately next to the user data area such as the second data = 6G2 will be recorded 5 new * second use Information (five), and then the second most _ case system, system FS#2 will record the third most The slot system FS#3, the second spare area SA2 of the 6D map is extended by the first spare area SA2 of the 6th to 6th drawings. In other words, when the second spare area SA2 of the 6A is shown When it is used up, it is possible to extend the second spare area SA2 of FIG. 6A by re-initializing and writing the information storage medium 300. In order to easily extend, for example, the preparation of the SA2 (4), the use direction of the spare area (ie, the spare area) will be made. The direction of the recorded data is opposite to that of the user data area (for example, 333). Even if the above logical overwrite is continued on the same logical sector number (logical sect〇rnumber, lsn), the defect table includes The amount of data does not increase, for example, false 5 and the logical sector numbers (LSNs) corresponding to the physical sector numbers (PSNs) l〇〇h to IFFh in the user data area are 〇〇h to FFh, and record the initial file system in the physical volume 13379pifl.doc 1271713 numbers (PSNs) lOOh to IFFh. The logical magnetic zone number (LSN) represents the logical magnetic zone address, and the physical magnetic zone number (PSNs) represents the physical magnetic zone address. In this case, remember When the additional user data is recorded and written to the information storage medium 300, the host will issue a command to the data recording and/or reproducing device 500 of FIG. 5 to cover the new file system of the younger one. The logical magnetic zone numbers (LSNs) of the system are 00h to FFh. If the data has been recorded using the space-slot map (SBM) or the post-write verification method to determine the logical magnetic zone numbers (LSNs) OOh to FFh, the above data records and/or The reproducing device determines the magnetic regions corresponding to the physical magnetic zone numbers (PSNs) 100h to lFFh as the defective regions. Then, the above data recording and/or reproducing apparatus records the first latest file system (e.g., FS#1) in a spare area (e.g., SA2). Fig. 7 is a diagram showing the defect generated by the first logical overwriting of the method of Figs. 6A to 6D. Referring to FIG. 7, the corresponding magnetic domain of the physical magnetic zone number (PSNs) 100h to lFFh of the initial slot system will be determined as the defective magnetic zone, and the replacement magnetic zone of the defective magnetic zone is a spare area (for example, Physical volume numbers (PSNs) llFFFh to llFOOh among SA2). When the first latest file system is recorded by the first logic to record the logical area numbers (LSNs) of the 〇〇h to FFh and then record additional user data for writing to the information storage medium, the host will Commanding the above information and/or reproducing device to overwrite the second most recent (four) key logic area number 〇^) is the magnetic area of _ to FFh. If the data is recorded in the magnetic region corresponding to the logical magnetic zone numbers (LSNs) 〇〇h to FFh by using the NZ map (sbm) or via the post-write verification method, the above data recording and/or reproducing device will correspond to The physical magnetic zone number (psNs) face to the lion's magnetic zone 13379piH.doc 18 1271713 is determined as a defective zone. Then, the data recording and/or reproducing apparatus 5 records the second latest slot system (e.g., FS#2) in a spare area (e.g., SA2). Figure 8 is a diagram showing the defect generated by the second logic overwriting of the methods of Figs. 6A to 6D. Referring to FIG. 8, the corresponding magnetic domain of the shell magnetic domain number (pSNs) 1〇〇h to 1FFh for recording the initial file system will be determined as the defective magnetic domain, and the replacement magnetic domain of the defective magnetic domain is the spare area. The cross-domain number (psNs) l lEFFh to 1 lEOOh (for example, SA2). Comparing the defect tables of Figures 7 and 8, although each time the overwrite is generated on the same logic, the area number (LSN), the defect table is generated, but only the entity of the replacement magnetic field included in each defect table is changed. The magnetic zone number (pSN) without increasing the amount of data contained in each defect table. And, a method of writing a person-recording storage side according to another embodiment of the present invention will be explained. In this embodiment, the file system is used to perform data overwriting. In order to perform the overwrite, the data record and/or regeneration of FIG. 5 is received from the host to reproduce the data being recorded by the logical sector number (LSN) and access the logical sector. = The physical volume number (PSN) (for example, leg to 1FFh) = (m) and the read data is transmitted to the host. The data records received and/or the equipment received by the regenerative device are recorded in the above-mentioned information storage and received. The ββ(4)s^^u is recorded and/or reproduced in the Jinjin _ 炱汛 炱汛 storage medium 300, then Data record 1. The space bitmap (SBM) and defect information will be transmitted to the host with 13379pifl.doc 19 ^71713 and other similar information. The host distinguishes the data logical configuration state of the user data = (for example, 333) and the actual data of the user data area by referring to the above-mentioned space bit map (SBM), defect information, and the like. The recordable area and the unrecordable data^ can be recorded to select the overwriteable area. In other words, one of the features of the overwriting method according to this embodiment of the present invention is that the host selects an overwritable area.
