Abstract
A disc clamping device having a spindle for rotating a disc, and a hub on top of the spindle with a flat, flared surface for supporting the disc. A cylindrical section, with an annular groove interrupted by inward recesses, is located above the flared surface. A wave washer with inwardly extending tabs is placed on the hub by aligning the inwardly extending tabs with the recesses in the annular groove. The washer is rotated to capture the tabs in the groove thereby compressing the washer against the disc.
