Abstract
A disk clamping mechanism for a disk driving device employed in an apparatus for writing information in a disk and reading the information recorded in a disk, such as a recording/reproducing apparatus, has a rotary system including a hub for centering a disk relative to and pressing the disk against the spindle hub of the disk driving device and a collet for pressing the hub toward the spindle hub, and a nonrotational system including carrier for moving the rotary system toward and away from the spindle hub, a collet supporting member supporting the collet and fastened to the carrier, a ball receptacle loosely fitted in the collet supporting member, and a spring urging the collet supporting member and the ball receptacle away from each other. The rotary system and the nonrotational system are joined by means of a spherical tip or a conical tip at a position on the lower side toward the spindle of the disk driving device below to a disk clamping surface so that tilting of the hub is corrected as the hub is fitted in the spindle hub attached to the spindle.
