Abstract: PURPOSE: To obtain a disk drive enclosure structure where a special form whose draft is zero is used in a die casting process. CONSTITUTION: A data storage disk drive 10 includes a spindle, which supports plural disks on the surface of a magnetic disk which are rotated around a common shaft and form a spindle assembly 18, and a rotary actuator which supports plural magnetic transducers on the surface of each disk. The disk drive includes a die cast disk drive enclosure structure 12 including the surface to which a spindle motor shaft and an actuator bearing shaft are set and where a predeterminate draft is zero. The enclosure structure includes a base cast member 14, which holds an electric connector arranged on the outside, and a cover cast member 16. The disk drive includes an electric passage from a flexible circuit to a comb-shaped part of the actuator. The disk drive includes a tubular chemical air filter arranged in a groove for diffusion integrated with the cover as one body.

Abstract: A flexible magnetic recording disk (18) is nonremovably enclosed in a rigid jacket (10). A wall (17) of the rigid jacket includes a movable wall-piece (29) which operates as a disk cleaning member. The disk is clamped to a spindle/collet drive assembly while the disk cleaning member is spaced from the adjacent surface of the disk. Only after clamping has been accomplished is the disk subjected to the friction force of the cleaning member.

Abstract: A cartridge filter for an enclosed magnetic disk drive is disclosed which includes a dual media drum type filter element in a recirculating filter assembly (14, 18) that surrounds the breather filter (27) and delivers air from the periphery of the disk stack (57) to the axial entry of the ventilated disk spindle assembly (45). The cartridge provides an extended media surface within a compact space for frequent cycling of the enclosed air volume through the filter.

Abstract: A data storage disk drive is provided with a spindle which supports a plurality of disks having at least one magnetic disk surface to form a spindle assembly for rotation of the disk surfaces about a common axis and a rotary actuator which supports magnetic transducers for movement in unison about respective disk surfaces. The disk drive includes a disk drive enclosure having die-cast generated predetermined zero draft geometries for mounting the spindle motor shaft and the actuator bearing shaft. The enclosure includes a base casting and a cover casting, each casting including structure for locating and retaining electrical connectors used for connecting to a planar electronics card located outside the drive enclosure. The disk drive includes an effective and easily manufacturable electrical path from a flex circuit to an actuator comb. The disk drive includes a tubular chemical breather filter arranged with integral housing and diffusion channels formed in the cover casting.

Abstract: A bearing seal assembly for an oscillating actuator, comprises an outer bearing raceway, an inner bearing raceway mounted concentric with the outer raceway, and an annular deformable liquid impermeable membrane having an axial length of not more than one tenth the radius thereof, an inner peripheral edge sealingly secured to the inner bearing raceway, and an outer peripheral edge sealingly secured to the outer raceway for enabling limited relative rotation between the inner raceway and the outer raceway with minimum axial distortion of said membrane. In one embodiment, the membrane is stretched to eliminate surface distortion under torsional stress. Another embodiment illustrates waves molded into the membrane for reducing torsional forces.
