ABSTRACT:
A spindle clamp for removably supporting a data disk wherein the clamp has a spindle adapted for rotation about a vertical axis. The top of the spindle is stepped, having an inner raised surface, an intermediate gap-forming surface and an outer disk-seating surface. A segmented annular jaw assembly rests atop the raised surface and forms an annulus having an outer diameter less than the inside diameter of the data disk. The radially inward portion of the jaw assembly has an inverted and truncated conical bearing surface in frictional contact with a conforming wedge surface of a cam member. Downward displacement of the cam member causes the wedge surface to move the individual segments of the jaw assembly in a radially outward direction. The cam member is moved pneumatically from a disk-releasing position to a lower disk-clamping position that positions the edges of the individual segments of the jaw assembly above the data disk. Simultaneously, the cam member contacts a portion of a load transfer member spatially situated between the cam member and the jaw assembly. Interaction of the cam member, the load transfer member and the jaw assembly forces the jaw assembly onto the upper surface of the data disk, thereby securing the data disk to the spindle.
