Microprocessor controlled rigid disk file subsystem |
摘要 |
An improved control system for a disk file includes head position control circuitry including at least one servo loop for controlling an electromechanical head positioner relative to a rotating data storage disk, a data controller for controlling reading and writing of data blocks from and to a storage surface of the disk, an interface circuit for connecting the disk file directly to data, address and control buses of a host computer, and a single microprocessor programmed to supervise operations of the head position control circuitry, data controller and interface circuit.
