A spring disk clamp is provided for securing one or more data storage disks to a disk drive without the need for screws. The disk clamp incorporates an angled surface defining the central opening of the clamp which is positioned adjacent a sloping surface of the hub. An external axial load applied to the clamp deflects the clamp, and allows a retaining member to be wedged between the clamp and the hub. Stabilizing features such as O-rings and the like are also eliminated as the clamp of the invention provides both radial and axial stabilization to the disk pack in its mounting to the hub.

A method for installing a printed circuit board assembly on a disk drive base plate is disclosed, as well as the corresponding structure used for this installation. Generally, the printed circuit board assembly includes a pair of bosses that are each disposed within a corresponding concave slot on the base plate. When installing the printed circuit board assembly, the bosses are disposed within their corresponding slot while the printed circuit is disposed at an angle relative to the base plate. Thereafter, the printed circuit board assembly is pivoted toward and into interfacing relation with the base plate at least generally about the bosses.
