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.
