Disk processing chuck
First Claim
1. A disk processing chuck for holding a memory disk, the disk having a central opening and planar sides for receiving magnetic media on both of the sides, the disk being bounded by a cylindrical outside diameter peripheral edge and chamfered edges extending between each of the planar sides and the peripheral edge, said chuck comprising:
- a disk retainer mount including a central disk support for mounting a circular chamfered edge of the disk bounding the disk central opening and a peripheral mount edge for receiving one of the outside diameter chamfered edges of the disk;
a retaining ring seated in said retainer mount, said ring including a multiplicity of spaced radial fingers extending cylindrically around said ring, each finger having a distal end extending to a first position outboard of said mount edge; and
wherein the distal ends are movable inwardly to a second position into clamping contact with the outside diameter peripheral edge of a disk mounted on said retainer mount.

Abstract
A memory disk having a central opening and planar sides for receiving magnetic media on both of the sides is bounded by a cylindrical outside diameter peripheral edge and chamfered edges extending between each of the planar sides. The peripheral edge is clamped by a disk processing chuck including a disk retainer mount having a central disk support for mounting a circular disk edge bounding the central opening and a mount cylindrical beveled edge receiving an outside diameter chamfered edge of the disk. A ring in the retainer mount includes a multiplicity of spaced radial fingers extending cylindrically around the ring, each finger having a distal end extending to a first position outboard of the disk peripheral edge. The distal ends are moveable inwardly to a second position by an inflatable bladder acting simultaneously against all the fingers, placing the distal end tips into clamping contact with the disk peripheral edge mounted on the retainer mount.
