Abstract: A disk drive spindle with a rotatable hub combines the advantages of a stationary shaft, a cartridge bearing assembly, and a motor mounted axially between the individual bearings of the cartridge bearing to rotate the hub with respect to the stationary shaft. The stator of the motor is mounted to the shaft so that it is disposed radially outwardly of the bearing assembly and at least partially axially between the individual bearings. The motor mount is cup shaped and has a central opening that axially receives and surrounds at least part of the bearing assembly, with the stator being secured to an outer surface of the cup. Alternately stated, one end of the bearing assembly is recessed within the mount.

Abstract: An improved self-loading magnetic head slider for recording and reading data on a magnetic storage disk, is characterized by the addition of aerodynamically designed wings used for lowering the slider close to the surface of the disk to a designed head-to-disk separation as the disk is rotated. The magnetic head slider does not contact the magnetic storage disk surface.
