First example of the structure of the ACA shown in Fig. 3 A displayed map 2.With reference to Fig. 3 A, ACA 213 comprises ACD#1310, ACD#2320 and ACD#3330.
ACA 213 wherein records to be used for not considering existing or new standard and the district of the public information of accesses disk.In other words, ACA 213 storage common application are in the public information table of the repertoire that uses under existing standard and new standard.ACD constitutes the public information table about each function.For example, ACD#1310 constitutes the public information table about " function 1 ", and ACD#2520 constitutes the public information table about " function 2 ", and ACD#3330 constitutes the public information table about " function 3 ".Function 1 can be driven system identification, and function 2 and function 3 can not be driven system identification.ACD only also can comprise the specific information that the drive system of identification and ACD function corresponding can be identified, but is not all to need in aspect all of the present invention.
ACD#1310 comprises public information 311 and specific information 312.Public information 311 comprises: ACD_ID 313, (that is the ID of identification ACD); But form voltinism information 314, whether display disc can be formatted; Spare area recordability/reproducibility information 315, the indication spare area is recordable or only reproducible; With UDA recordability/reproducibility information 316, indication UDA is recordable or only reproducible.
Drive system can determine whether ACD#1310 is about discernible function based on ACD_ID 313.In other words, if drive system is known ACD_ID 313, then ACD#1310 is confirmed as about discernible function.Otherwise ACD#1310 is confirmed as about non-discernible function.
In addition, even drive system is not known ACD_ID 313, but drive system also can be carried out minimum proper handling about non-recognition function at least based on being included in field in the public information table.
ACD#2320 also comprises public information 321 and specific information 322.But public information 321 comprises ACD_ID 323 and comprises the public information table of form voltinism information 324, spare area recordability/reproducibility information 325 and UDA recordability/reproducibility information 326.
Preferred and inessential is, from coiling 200 inboard laterally radially or from coiling 200 inboard, the lateral ACA 213 that radially uses in order.In addition, when defective was detected when data are written into ACD piece among the ACA 213 or as the result of write-verify checking, data were recorded in subsequently the ACD piece.
Simultaneously, the public information of ACD also can comprise the recordability/reproducibility information about coiling the district except spare area and UDA 222 on 200.Yet preferred and inessential is that public information does not comprise the recordability/reproducibility information about TDMA 216.Status information about the ACD piece that wherein records ACD in ACA 213 is recorded among the TDMA 216.Therefore, if the status information of ACD is set to prevent to write TDMA, then the status information about the ACD piece can not be recorded or upgrade.
In other words, owing to be recorded among the TDDS 410 that is included in TDMA 216 about the status information of the ACD piece among the ACA 213, so should in ACD, be defined about recordability/reproducibility information of TDMA 216.If the recordability/reproducibility information about TDMA 216 is defined, and be configured to prevent to write among the TDMA 216, then when new ACD piece was added among the ACA 213 or change existing ACD piece in ACA 213, the ACD status information of change can not be recorded among the TDMA 216.In the case, each the time of day that is included in ACD piece among the ACA 213 can not be known, and this has to be difficult to obtain effective ACD.
Simultaneously, according to the use of write-once information recording medium, TDMA 216 can intactly or partly be included in the spare area 221.In the case, spare area recordability/reproducibility information should not comprise the information about TDMA 216, because preferably the public information of ACD does not comprise TDMA216 recordability/reproducibility information.
Another example of the structure of ACA 213 shown in Fig. 3 B displayed map 2.Except comprising TDMA recordability information 317 and data field recordability/reproducibility information 318 and public information 321, public information 311 comprises that second example shown in Fig. 3 B is similar to the example shown in Fig. 3 A TDMA recordability information 327 and the data field recordability/reproducibility information 328.
Particularly, opposite with the example shown in Fig. 3 A, the TDMA recordability information 317,327 shown in Fig. 3 B is included in the public information 31,312.Yet, the information that TDMA recordability information 317,327 does not comprise about the TDDS among the TDMA 216 is even so that also always make the ACD status information be recorded among the TDDS when TDMA recordability information 317,327 is set to prevent to write among the TDMA 216.
Simultaneously, although not shown among Fig. 2, TDMA 216 also can be dispensed in the data field, such as UDA222.In this embodiment, the TDDS 410 that wherein records the status information of ACD can be included among the TDMA 216 that is distributed in the data field.In the case, even be forbidden when writing data field/read from the data field, be included in TDDS in the data field and should also be recordable/reproducible.
In other words, TDMA recordability information the 317, the 327th is about the information of the recordability of all parts of the TDMA except TDDS 410 216, and data field recordability/reproducibility information the 318, the 328th, about the information of the recordability/reproducibility of all parts of the data field except TDDS 410 or TDMA 216.That is, TDDS410 should be always recordable on the write-once embodiment of information recording carrier.
Fig. 4 shows the detailed structure according to the TDMA that is equipped with the district that wherein records the ACD status information 216 of the embodiment of the invention.With reference to Fig. 4, TDMA 216 comprises TDDS 410, TDFL 420 and RMD 430.
