Abstract
Apparatus for centering and clamping a flexible magnetic recording disc in a disc drive comprises a spindle having on its outer end a face for supporting the associated recording disc and also has a recess within that face and a disc clamping element which cooperates with the spindle and includes a plurality of resiliently deflectable fingers extending in a direction both angularly outwardly of the axis and toward the spindle with means for deflecting the fingers radially outwardly for centering the associated recording disc with respect to the center of the spindle, and means for selectively moving the clamping element toward and away from the spindle and into and out of releasable engagement with the recording disc and spindle.
