ABSTRACT:
A chuck holds a disk by the inside diameter with a plurality of contact surfaces at the end of fingers. Axial motion of an actuator is translated into outward radial movement of the fingers to place the contact surfaces in contact with the inside diameter of the disk. The force that is applied to the disk is limited to reduce or eliminate warping or curvature of the disk, e.g., a sleeve that surrounds the fingers can be used as a hard stop to physically limit the range of outward radial movement of the fingers.
