摘要： A disk drive is disclosed with reduced resonance. The disk drive comprises a disk, a fixed spindle shaft disposed axially through the disk, a spindle motor for rotating the disk about the fixed spindle shaft, wherein a resonance is associated with the spindle motor rotating the disk. The disk drive further comprises a head, an actuator arm for actuating the head radially over the disk, a base, and a cover attached to the base to form a head disk assembly chamber. The cover comprises a shaft aperture positioned over the fixed spindle shaft, the shaft aperture for receiving a fastener for attaching the cover to the fixed spindle shaft. The cover further comprises a plurality of slots proximate the shaft aperture, wherein the shaft aperture and slots provide a flexible support for the fixed spindle shaft which reduces the resonance associated with the spindle motor.

摘要： A disk drive including a head disk assembly, a planar printed circuit board and a vibration damping system. The vibration damping system is fixed adjacent the outer surface of the printed circuit board and includes an external planar member of compressible foam composition and a substantially-planar rigid mass damper of like shape and extent and arranged so that the external planar member contacts both the outer surface of the printed circuit board and the upper major surface of the mass damper. The major surfaces of the mass damper include upwardly-convex bosses for receiving fastening screws to maintain a predetermined separation distance between the printed circuit board and the mass damper that is somewhat less than the unconstrained thickness of the external planar member of compressible foam composition.

摘要： A magnetic disk drive includes a base which supports a head stack assembly having a coil portion, a flex circuit cable having a grounding portion, and a flex clamp. The disk drive further includes a voice coil motor (VCM) formed from the coil portion's interaction with upper and lower VCM plates that carry at least one permanent magnet. The disk drive includes a Z-shaped grounding portion which wraps around one end of the flex clamp and permits a single screw to secure that end of the flex clamp to the base and simultaneously make grounding contact with the grounding portion and an elongated protrusion extending from one of the VCM plates that is adjacent to the flex clamp to hold that end of the flex clamp against the base when the VCM plates are fastened to the base.

摘要： A disk drive includes an enclosure that defines an exterior surface, the enclosure including a base, a cover and a hinge mechanically coupling the base to the cover such that the hinge forms a portion of the exterior surface of the enclosure. A spindle motor is attached to the base, a disk is mounted to the spindle motor, and a head stack assembly is pivotally coupled to the base. A method of manufacturing a disk drive includes a single (injection, for example) molding step to form an enclosure including the base, the cover and a hinge that mechanically couples the base to the cover such that the hinge forms a portion of the exterior surface of the enclosure. The spindle motor may then be attached to the base, the disk or disks mounted to the spindle motor and the head stack assembly may be pivotally coupled to the base. Alternatively, the base and the cover may be separately provided and the hinge may be molded (by an insert molding process, for example) onto the base and the cover to mechanically couple the base to the cover such that the hinge again forms a portion of the exterior surface of the enclosure.

摘要： A disk drive with reduced acoustic noise is disclosed. The disk drive comprises a disk, a head, an actuator arm for actuating the head radially over the disk, a base, and a cover attached to the base to form a head disk assembly chamber. The cover comprises an inner layer having a depression, the depression comprising a convex surface and a concave surface, an outer layer attached opposite the concave surface to the inner layer, the inner layer and the outer layer thereby defining walls of a cavity. The cover further comprises a damping medium disposed within the cavity, whereby the inner layer, the outer layer, and the damping medium form a multi-layer noise-damping sandwich which reduces noise emitted by the disk drive.
