ABSTRACT:
A collet for clamping recording media to the spindle of a floppy disk drive has a ball joint-type suspension, such as may be provided by having the collet ride on a hemispherical bearing, whereby the center of action of the media clamping forces supplied by the collet remains substantially centered on the spindle, even if the spindle and/or the collet lack perfect dynamic symmetry or concentricity.
