As described below, according to write-once information storage medium of the present invention may be wideer than conventional information storage media needs the spare area, in order to use according to overriding on the defect management actuating logic of the present invention.Therefore, at the initialization information storage medium or in the process of use information storage medium, the expansion spare area is preferred, but not necessarily.In order in the use of information storage medium, to expand the spare area, with user data record side shown in Fig. 4 A and 4B in the opposite direction in the spare area record data be preferred, but not necessarily.
Now, the information storage medium 300 that shows with reference to Fig. 3 A and 3B is described the method that overrides data according to two kinds of embodiments of the present invention in detail.
In the method that overrides data according to the embodiment of the present invention, can use the logical overwrite technology in can not be, to override data by the write-once information storage medium of physical overwrite.
Fig. 5 is the block scheme according to the equipment 500 of data recording of one embodiment of the present invention and/or reproduction.As shown in Figure 5, this equipment 500 comprises write device/reader 510, controller 520 and storer 530.This write-once information storage medium 300 is identical with the write-once information storage medium of Fig. 3 A.
Write device/reader 510 is write data write-once information storage medium 300 under the control of controller 520, and reads the data that write with checking data from this write-once information storage medium.
At record and/or when reproducing on the write-once information storage medium 300 data, controller 520 utilizes the TDMA that is included in the write-once information storage medium 300 to carry out defect management.
Now, by with the file system of a renewal example, describe above-mentioned data of in write-once information storage medium 300, carrying out in more detail and override by data recording and/or the reproducer 500 of Fig. 5 as the data that will be written.
If data recording and/or reproducer are carried out defect management to write down and/or to be reproduced in the data in the write-once information storage medium, then can be updated in the file system that writes down in the write-once information storage medium by defect management.In other words, data recording and/or reproducer 500 receive about the logical address of the data of the file system upgraded and the write-once information storage medium file system with storage update from main frame, and check with this logical address physical address corresponding whether occupied by data thereafter from SBM.SBM is written into device/reader 510 and reads and store into the storer 530 from write-once information storage medium in advance.If determine that this physical address is occupied by data, the district that then has this physical address is confirmed as defect area.Then, the file system that record upgrades in branch is equipped with the spare area in replace defective district.
If data recording and/or reproducer 500 are not used this SBM, then this record and/or reproducer 500 can determine that the data field that be occupied is a defect area by verify-after-write method, then record updating file system in the spare area.Thereafter, the TDDS that record upgrades in TDMA 321 and the TDFL of renewal.
Fig. 6 A is illustrated in the method that overrides the file system of renewal in the write-once information storage medium 300 to Fig. 6 D.In the method that reference Fig. 6 A describes to 6D, first and second spare areas 331 and 332 are confirmed as SA1 and SA2, and are dispensed on the head and the afterbody of data field (for example the data field 330).Equally, the district of memory file system is distributed in the head of user data area 335.
In Fig. 6 A, initial file system FS# 0 is recorded in head from user data area 335 in the alignment area in precalculated position.In Fig. 6 B, in user data area 335, first user data 601 and then initial file system FS# 0 is recorded, then, according to the overwrite method of the invention described above embodiment, after the second spare area SA2 recording defect management, produce first FS#1 of updating file system.In Fig. 6 C, in user data area, second user data 602 and then first user data 601 is recorded, then second FS# 2 of updating file system and then first FS#1 of updating file system be recorded.In Fig. 6 D, in user data area 335, second user data 603 of renewal and then second user data 602 is recorded, then the depth of the night new file system FS# 3 and then second FS# 2 of updating file system be recorded.
Expand among the second spare area SA2 that the second spare area SA2 among Fig. 6 D shows from Fig. 6 A to Fig. 6 C.In other words, when the second spare area SA2 of Fig. 6 A ran out, the second spare area SA2 of Fig. 6 A can expand by write-once information storage medium 300 is reinitialized.For expansion easily as the spare area of SA2, the service orientation of spare area, promptly the direction of record data in the spare area is set to and user data area, promptly in 335, the direction of record data is opposite.
Even go up the above-mentioned logical over-write of continuation at identical logic sector number (LSN), the data volume that comprises in defect list does not increase.For example, suppose in user data area with physical sector number (PSN) 100h to the corresponding LSN of 1FFh be 00h to FFh, and initial file system is recorded in PSN 100h in 1FFh.The address of LSN presentation logic sector, PSN represents the address of physical sector.
Like this, because extra user data is recorded in the write-once information storage medium, data recording and/or reproducer 500 that main frame issues commands to Fig. 5 override the first updating file system with the LSN00h that is recorded in initial file system to FFh.If utilize SBM or handle to determine that by write-verify checking LSN 00h is occupied by data to FFh, then data recording and/or reproducer definite with PSN 100h to the corresponding sector of 1FFh as defect area.Then, (as SA2) writes down the first updating file system (FS#1) in the spare area for data recording and/or reproducer.Fig. 7 shows the defect list that produces to first logical over-write in the method for Fig. 6 D by Fig. 6 A.With reference to Fig. 7, be confirmed as defective sector with the PSN 100h that wherein writes down initial file system to the corresponding sector of 1FFh, and the replacement sector of this defective sector is that the PSN 11FFFh of in the spare area (as SA2) is to 11F00h.
When by first logical over-write with the first updating file system log (SYSLOG) at sector LSN 00h to FFh, when the additional user data were recorded in the write-once information storage medium then, Host Command data recording and/or reproducer override the second updating file system at sector LSN 00h in FFh.When utilize SBM or by write-verify checking handle to determine with LSN 00h when the corresponding sector of FFh is occupied by data, data recording and/or reproducer are definite to be defective sector with PSN 100h to the corresponding sector of 1FFh.Then, data recording and/or reproducer 500 write down the second updating file system (as FS#2) in spare area (as SA2).
Fig. 8 shows the defect list that produces to second logical over-write in the method for Fig. 6 D by Fig. 6 A.With reference to Fig. 8, be confirmed as defective sector with the PSN 100h that wherein writes down initial file system to the corresponding sector of 1FFh, and the replacement sector of this defective sector is that the PSN 11EFFh of in the spare area (as SA2) is to 11E00h.
Comparison diagram 7 and 8 defect list though each the execution on identical LSN produces defect list when overriding, do not have in the data volume that is included in each defect list under the situation of increase, and the PSN that only is included in the replacement sector in each defect list is changed.
Now, with the method for describing in detail according to another implementation of the invention that in write-once information storage medium, overrides data.In this embodiment, utilize file system to carry out data and override.
Override in order to carry out this, the data recording of Fig. 5 and/or reproducer 500 receive order from main frame and are recorded in the data of sector LSN 00h to the FFh with reproduction, visit the PSN corresponding with LSN, for example, 100h comes sense data to 1FFh, and transmits these data of reading to main frame.
When main frame attempt to proofread and correct the data that receive from data recording and/or reproducer and after the data of record correction write-once information storage medium, or when attempting in addition in write-once information storage medium 300 record from data that data recording and/or reproducer receive, data recording and/or reproducer 500 with SBM, defect information, or the like be transferred to main frame.By reference SBM, defect information, or the like, consider the state of the user data area of distribute data in logic (promptly 333) and the physical record situation of user data area, main frame is distinguished recorded data district and can not recorded data zone, thereby selects to override the district.In other words, the characteristics of the overwrite method of this embodiment are to be selected to override the district by main frame according to the present invention.
Utilizability on the industry
The overwrite method of an embodiment is suitable for the write-once information storage medium of the user data area with large storage capacity after according to the present invention.The overwrite method of previous embodiment is by overriding the consumption that new data can prevent user data area in the spare area of using in defect management according to the present invention.
As mentioned above, in the present invention, override technology, in the write-once information storage medium that can not physics overrides, can carry out overriding by applied logic.Therefore, the data that are recorded in the write-once information storage medium can be changed or upgrade.Equally, when needs are recorded in data in the fixed area of write-once information storage medium, for example, when file system is updated, the file system of this renewal is recorded on the physical address different with the physical address that writes down initial file system, but the logical address of file system that writes down this renewal is identical with the logical address that writes down initial file system.Therefore, main frame approval file system always is recorded in the fixing district, thereby easily visits and reproduce this document system.
