<p>For centering and clamping a disc-like recording medium on the spindle of a floppy disk drive, there is an expandible collet (21) comprising a plurality of flexible fingers (55) which have generally tangentially extending arcuately profile ribs for clamping the disk against the spindle. Due to the flexibility of the fingers (55), the ribs have substantially constant, line-like footprint, which enables them to apply a predetermined, essentially constant, normal clamping pressure to the recording medium, even if the collet is slightly tilted with respect to the spindle, or if the mating surfaces of the collet (21) and spindle are not absolutely parallel or perfectly flat.</p> |
