Abstract
For centering and clamping a disk-like recording medium on the spindle of a floppy disk drive, there is an expandible collet comprising a plurality of flexible fingers which have generally tangentially extending arcurately profile ribs for clamping the disk against the spindle. Due to the flexibility of the fingers, the ribs have a 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 slighted tilted with respect to the spindle or if the mating surfaces of the collet and spindle are not absolutely parallel or perfectly flat.
Claims4
In a floppy disk drive having a rotatably driven spindle, and a collet with a plurality of flexible fingers for clamping recording media to said spindle;
- said collet having improved media engaging means comprising
- generally tangentially extending, arcuately profiled ribs
- each of said fingers supporting a respective one of said ribs, whereby said collet has a substantially constant line-like contact ara for maintaining a preselected clamping pressure on said media despite any tolerance permitted imperfection of said collet spindle.
