ABSTRACT:
According to the present invention, a synchronization code section preceding a synchronization byte section serving as data sync before a data area in a recording area of a sector is caused to include not a conventional single densest pattern but a pattern capable of synchronizing bytes. With this arrangement, data in the recording area can be correctly reproduced when the data is recorded in an optical disk of a phase change scheme by using a random shift.
