Adapter for disk drive and method of communication between adapter and disk drive

摘要

A disk drive (31) has a slot to receive a disk cartridge containing a disk and drives the cartridge. A disk-cartridge-type adapter (1) is shaped to be inserted into the slot of the drive (31). The adapter (1) has a controller (72) to transfer data between the adapter (1) and the drive (31) through the heads (51,52) thereof. The controller (72) formats data so that the formatted data may fit into at least part of a disk format having tracks and sectors handled by the drive (31). The controller (72) assigns a specific one of the tracks to the formatted data and transmits the track with the data to the drive. Thus, the data processing efficiency of the adapter (1) and data transfer efficiency between the adapter (1) and the drive (3) can be improved. <IMAGE>
