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 ACA213 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 311,312.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.
