ABSTRACT:
A disk drive of a driving device for a CD-R (compact disk recordable) disk or a CD-RW (CD-rewritable) disk, when a read-out error occurs due to a data mismatch in the PMA (program memory area) of the CD-R disk, it saves the address information concerning a start and a stop of a readable track which is recorded in the PMA, accesses a corresponding track based on the saved address information, reads out data of the accessed track, and then, records the read-out data in a new CD-R disk. Thereby, the larger amount of data can be recovered even if an error occurs in reproducing during the reading of the PMA of a recordable disk or a rewritable disk.
