Actuator Less Vector Clamping Apparatus for Rigid Disk Media

      A means for disk clamping by which no actuator is used is
disclosed.  The disk is pushed on and off, over the radial clamp
fingers, which provides the clamping pressure used during a spindle
operation.

      This invention provides a number of fingers 2 machined from
plastic.  The fingers 2 provide individual spring-type action that
clamps and centers the disk. In operation, the disk is slid over the
surface of the clamp fingers by means of the angled lead-in 3.  The
reverse angle 4 on the bottom side of the fingers assists in holding
it down to the surface of the chuck 1 and provides the consistent
clamp pressure.  Draw rod 5 stays in clamped position (see the
figure).
