Abstract: In an embodiment of the present invention, at least one mechanical fastener is used to mount a voice coil magnet assembly of a hard disk drive on a housing of the hard disk drive. A layer of a material having a low friction coefficient is disposed between the housing and the voice coil magnet assembly.

Abstract: An automated system for setting the linear distance from a mounting surface of a pivot cartridge to critical features on actuator arms is disclosed. This distance is set to eliminate the tolerance incurred via normal manufacturing of these components. The system adjusts for every component to customize each actuator and/or pivot assembly to meet the functionality requirements for disk drives.

Abstract: A disk clamp for securing data storage disks to the hub of a spindle motor in a hard disk drive has a circumferential rib protruding from a lower surface of the disk clamp. A complementary recess is formed in the hub of the spindle motor for closely receiving the rib on the disk clamp. The inner diameter of the rib and the outer diameter of the recess are closely toleranced to provide a very precise centering feature for mounting and aligning the disk clamp with respect to the hub and spindle motor. This design reduces the complexity of the tooling and fixtures required to complete the assembly and the overall part cost is reduced.

Abstract: An apparatus for securing the internal rotational components of a disk drive utilizes an annular clamp retention device. The clamp retention device has a rigid, metallic, main ring body from which protrudes a plurality of compliant tabs having a generally L-shaped cross-section. The compliant tabs extend radially inward from the body to form an inner circular array of the tabs. In addition, a plurality of rigid planar flanges, which are larger than the compliant tabs, extend radially outward from the body. The compliant tabs are designed to engage the hub and cartridge of the disk drive rotational components at the upper end of the disk stack.
