ABSTRACT:
A disc drive (A) for data transfer between a magneto-optical disc (B) and a host (C) is provided. The disc drive reads and stores in a RAM (12) medium identification information unique to the magneto-optical disc (B) and DMA information (B2) including a list of addresses indicating defective areas upon loading, and performs address conversion with reference to the DMA information (B2) for the data transfer. A CPU (11) checks if the medium identification information obtained when loading the magneto-optical disc (B) is identical with or different from medium identification information obtained in the previous loading. The CPU (11) allows the reading of DMA information (B2) and replacing of the previous DMA information remaining in a DMA information storage area (12D) of the RAM (12) with the newly obtained DMA information only when the newly obtained medium identification information is different from the previous medium identification information.
