System for data communication between disk adapter and disk cartridge drive where adapter controller assigns specific track to formatted data to be sent to drive

摘要

A method of communication between an adapter and a drive improves the data processing efficiency of the adapter and data transfer efficiency between the adapter and the drive. The drive has a slot to receive a disk cartridge containing a disk and drives the cartridge. The adapter is shaped to be inserted into the slot of the drive. The adapter has a controller to transfer data between the adapter and the drive through the heads thereof. The controller 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. The controller assigns a specific one of the tracks to the formatted data and transmits the track with the data to the drive.
