Abstract
A spindle clamp for supporting a disk includes a radial control member that is in contact with an opening through a jaw and that has a contour such that radial expansion of the jaw is induced during initial movement of the jaw toward a registration surface for seating the disk. However, the contour is such that further movement of the jaw toward the registration surface is an axial motion, rather than a combination of axial and radial motion. In one preferred embodiment, the jaw is unitary, but is configured to enable the radial expansion while having sufficient rigidity to reliably clamp a data disk seating on the registration surface. The jaw may include a lip which is configured to contact the major surface of the disk opposite to its contact with the registration surface.
