ABSTRACT:
An electronic circuit apparatus is provided comprising a component disk drive, and an electronic circuit implementing the component drive for local storage as an alternative to costlier solid state memory, wherein the electronic circuit has at least one function not related to the operation of the component disk drive, and wherein the electronic circuit uses information stored on the component disk drive to perform the non-storage related function. The apparatus is suitable for a plurality of electronic devices and for electronic circuit applications residing in a card enclosure adapted for plugging into an electronic device or computer. In the preferred embodiment, the component disk drive comprises a disk with a single recording surface mounted directly to a flat motor, a low profile actuator assembly including a single suspension supporting an MR head, and means for "parking" the head at the center of the disk. The preferred electronic circuit apparatus is enclosed in a PCMCIA type II or III card wherein the component disk drive occupies no more than 50% of the card area, and the remaining card area is populated by electronic components including nonstorage functions.
