Abstract
A system is disclosed for clamping disks in a spaced parallel relationship around a circular hub in a disk drive storage system. An annular clamp is provided which includes tabs extending inwardly into the aperture of the annular clamp which define a slightly smaller aperture. When a collapsing force is applied to the annular clamp, these tabs are displaced outwardly such that the annular clamp may be placed over the circular hub. The circular hub includes a lip for receiving the tabs and prohibiting axial movement of the annular clamp in response to a release of the collapsing force. Annular spacers are also disposed around the circular hub between adjacent disks. In a preferred embodiment of the present invention, each annular spacer includes multiple pads on each side thereof, minimizing any disk distortion which may be caused by spacer size variations.
