ABSTRACT:
An optical disk drive for driving an out-of-specification disk such as a CCCD. When the out-of-specification disk, such as a CCCD (Copy-Controlled CD), is loaded in the optical disk drive, a system controller of the optical disk drive reads TOC data in a first session and TOC data in a second session. When a contradiction exists between the TOC data in the second session and the TOC data in the first session, the system controller deems the disk to be not a within-specification disk but an out-of-specification disk, thereby diminishing the number of retry operations for reading data or a retry time, and reading data by means of generating a synchronization bit SYNC through use of an internal counter.
