摘要

The data memory system (1) the memory space of the data the optical disk which it possesses (3) (2) (is desirable, CD, DVD and BD), the disk drive where the disk (2) is suited for the read-out of information in between/entry (10), and disk drive the host device which can cooperate (20) with it has. Disk drive (10), host device (20) from, entry command (WRITE (10); WRITE (12) {SB=0}; WRITE (12) {SB=1}) or it reads out, command (READ (10); READ (12) {SB=0}; In order READ (12) {SB=1}) to receive, it is planned. As for disk drive, normal mode, and it is possible to operate at least with one extended mode. As for disk drive, the host (20) from responding to the mode selective command which is received, that operational mode, you set to one mode to which among of modes corresponds. At least, while writing in when error occurs, the medium access device with extended mode operates to the manner which is different by comparison with normal mode.
