To describe in more detail now test position information will be included in reason in the temporary defect management information.As mentioned above, temporary management information comprises temporary defect management information and temporary defect information, and comprises not shown records management information.According to one side, records management information is room figure (SBM).Whether SBM represents to use bit value based on record block data to be recorded in the district of recording medium.Temporary management information is recorded in the temporary defect management information area (TDMA).

For effective use of TDMA, when needs upgrade a part of temporary management information, only in TDMA, upgrade this part.When the temporary defect informational needs is updated and SBM when not needing to be updated, in next available area of TDMA, only upgrade temporary defect information.In the case, the temporary defect recording of information position change that writes down at last.Therefore, temporary defect management information need be updated.Similarly, when not needing to upgrade temporary defect information, in next available area of TDMA, only upgrade SBM as needs renewal SBM.In the case, because the change of the record position of the SBM of last record, so also need to upgrade temporary defect management information.

As mentioned above, because temporary defect management information must be stipulated the positional information about the part of upgrading, so when only upgrading the temporary management information of part of records in TDMA, temporary defect management information also must be updated.In other words, when dish 100 was loaded in the drive system, the temporary management information that detects last record concerning drive system was difficult.For head it off, be included in the temporary defect management information about the positional information that is included in each information in the temporary management information, and temporary defect management information is recorded in the end of TDMA.Therefore, by read the positional information about the temporary management information of last record from temporary defect management information, drive system can easily detect the temporary management information of last record.In this respect, temporary defect management information is sequentially recorded in TDMA.

Drive system can be distinguished the district that comprises the district of data and do not comprise data in temporary defect management information, and detects the data block of last record.Can by from coil 100 read radio frequency (RF) signal determine the dish the district whether comprise data.Therefore, when test position information is included in the temporary management information, preferably test position information is recorded in the temporary defect management information.

Because, when dish 100 is loaded into drive system, the data block of drive system by visit last record in TDMA, the temporary management information that detects temporary defect management information and detect last record from temporary defect management information from data block read the temporary management information that is lastly recorded on the dish 100, so test position information is recorded in the temporary defect management information.Drive system is carried out write/read operation based on the temporary defect management information of last record.For this reason, test position information is comprised in that disk drive must at first detect it so that data are recorded on the dish 100 or from the temporary defect management information TDDS #i of the last record that coils reading of data on 100, therefore allow easily to detect at once positional information and test position information about temporary defect information TDFL #i.

Do not consider whether another temporary management information is updated, comprise that test position information allows easily to detect test position information based on the address of the temporary defect management information TDDS #i of last record from TDMA in temporary defect management information TDDS #i.If test position information is recorded in the district except that the temporary defect management information TDDS #i of last record, then the temporary defect management information TDDS #i that writes down at last also must comprise the pointer in district that is used for the detection of test position information for this.In the case, detection for test position information, Ji Lu temporary defect management information TDDS #i is detected with the pointer of acquisition corresponding to the district that comprises test position information at last, and uses this pointer to detect the district that comprises test position information, therefore causes expense.

Fig. 6 B illustrates the data structure that is recorded in such as the temporary defect management information TDDS #i on the double record layer disc 100 of the dish shown in Fig. 2 C and the 2D.Temporary defect management information TDDS #i comprises the identifier that is used for temporary defect management information TDDS #i and about the information of the record position of corresponding temporary defect information TDFL #i.With reference to as described in Fig. 4 A to 4D, be repeated record several times as before according to the temporary defect information TDFL #i of the embodiment of the invention.Therefore, comprise pointer about the information of the record position of temporary defect information TDFL#i corresponding to the record position of each temporary defect information TDFL #i.Especially, the temporary defect management information TDDS #i shown in Fig. 5 B comprises P pointer, is repeated to write down P time for each pointer of each temporary defect management information TDDS#i.

And, on double record layer disc 100 the temporary defect management information TDDS #i of record describe the user data in the user data area be lastly recorded in the first recording layer L0 the address, be lastly recorded in the replacement in the spare area of the first recording layer L0 the address, be lastly recorded in the address of the user data in the user data area of the second recording layer L1 and be lastly recorded in the address of the replacement in the spare area of the second recording layer L1.Therefore, only by user data and replacement with reference to last record, the user is utilization dish 100 easily.

Similar with single record layer disc 100, temporary defect management information TDDS#i also comprises test position information #i and write protection information #i.Therefore, even disk drive not access drivers and dish block of information or do not carry out defect management can not detected testable district yet and are directly visited testable district when scanning the tested test section of record condition wherein.And, can avoid record in the district of not expecting.

Fig. 7 illustrates the data structure of temporary defect information TDFL #i.With reference to Fig. 7, temporary defect information TDFL #i comprise the identifier that is used for temporary defect information TDFL #i and about defective #1, #2 ..., the information of #k.About defective #1, #2 ..., the information of #k is that the position of expression defective and replacement and defect area comprise single defect block or comprise the status information of continuous defect piece.

Fig. 8 A and 8B illustrate the data structure according to the driver of the embodiment of the invention and dish block of information.With reference to Fig. 8 A; when temporary defect information TDFL #i and temporary defect management information TDDS #i are recorded among the TDMA shown in Fig. 4 A or 4B respectively, write protection information #i, to the pointer of the position of temporary defect information TDFL#i and to the pointer of the position of temporary defect management information TDDS #i by with the recording operation unit record in driver and dish block of information.With reference to Fig. 8 B; when temporary defect information TDFL #i and temporary defect management information TDDS #i are recorded when being included among the temporary management information district TDMA #i among the TDMA shown in Fig. 4 C or 4D, write protection information #i and to the pointer of the position of temporary management information district TDMA #i by with the recording operation unit record in driver and dish block of information.

According to the embodiment of the invention, write protection information (it is recorded among driver and dish block of information and the temporary defect management information TDDS #i) does not allow other data to be recorded on the dish 100.Even can comprising, write protection information is illustrated in that write-protect on the whole dish 100 is enabled or the still information in recordable district is enabled in the flag information of not enabled and expression write-protect.For example, first bit of write protection information is set to represent that write-protect is enabled or the flag information of not enabled, and each other bit is configured to represent that at least one fate is recordable or is not recordable.If write-protect is enabled, then second bit of write protection information can represent that driver and dish block of information are recordable or are not recordable.In addition, second bit can represent that driver and dish block of information are recordable or are not recordable, and the 3rd bit can represent that DMA is recordable or is not recordable.Third and fourth bit can represent that DMA and spare area are recordable or are not recordable.

According to aspects of the present invention, when write protection information was recorded, following district may be recordable.

In a district,, in driver and dish block of information, also allow data recording even write protection information is recorded on the dish 100 and can not writes down other data again.In other words, driver and dish block of information are not recorded to enable write-protected write protection information influence.Therefore, can change write protection information.

In another district, even write protection information is recorded to enable write-protect, a part of driver and the dish block of information distributed for write protection information are not influenced by write-protect yet.In other words, in a part of horse driver and dish block of information, allow data recording.Therefore, write protection information can be changed.

In another district, even write protection information is recorded to enable write-protect, temporary defect management area (TDMA), driver and dish block of information and spare area be not by write-protect influence (that is, allowing data recording) in these districts.Therefore, write protection information can be changed.And, even after the record of write protection information, also can carry out defect management.

If the error correction rate when reproducing the data that are stored in the user data area in the data block of user data area is lower than predetermined reference value, then can carry out defect management, thereby data block is counted as producing the wrong higher district of possibility, the data that were stored in the data block before the reproduction of data are written in the spare area, and data block is confirmed as defect area.

According to an aspect of the present invention, comprise that as fruit tray 100 then the spare area district is confirmed as recordable district at least above a district.
