ABSTRACT:
An autochanger of writable discs automatically transfers a write-once optical disc between a disc accommodation unit and a recording/reading device where data are recorded into the optical disc and read from that. In order to shorten a disc loading time, address information of sectors in which the latest defect management information is stored is written into an erasable non-volatile memory IC and renewed when a new defect sector is found in the optical disc.
