6/730664

Inventors:

Thomas D. Carroll - Campbell CA
Clifford B. Akers - Campbell CA

International Classification:

G11B 5012
G11B 582

US Classification:

360 97

Abstract:

An improved disk drive device including a disk of recording media and having a central aperture, which disk is supported at its periphery by a cylindrical housing. A spindle motor is positioned at the outer periphery of the housing along with a single set of bearings, also positioned at the other periphery of the housing, to cause rotation of the housing relative to a base. A stepper motor is positioned with its shaft protruding through the center aperture of the disk and directly coupled to read/write heads. The stepper motor shaft is positioned parallel to but offset from the center line of the disk so that rotation of the stepper motor shaft causes the read/write heads to translate along an arc across the surface of the disk. The arc extends from the inner track of the disk to the outer track thereof.
