Abstract of the Disclosure A hard disk drive memory cassette, for insertion into the housing of an electronic digital processor to be connected to the processing system, includes a housing having therewithin at one end, a hard disk drive having a single disk and, at the other end a connector. A printed circuit board providingcontrol functions, including track seeking, track following and read/write signal timing, normally mounted beneath the disk drive, is now disposed between the connector and the disk drive within the housing. The printed circuit board is connected to selected terminals of the connector to receive requests, in the form of signals, from the electronic digital signal processor and is connected to the actuator motor, the disk motor and the transducers of the had disk drive, toprovide required control signals therefor. A preferred embodiment is of the PCMCIA form factor, 54 mm wide, 85.6 mm long and 5 mm thick, employing a PCMCIA connector as the electrical interface and a 1.3 form factor hard disk drive as the rotating memory file. The hard disk drive memory cassette is of thesame size and shape as a solid state memory cassette of the same form factor and may be substituted therefor.
