Patent ID: 8074239

Claim:
A spindle clamp for supporting a disk comprising: a unitary jaw having an axial opening and having a geometry which includes structural features enabling radial expansion upon application of radial force applied along said axial opening, said unitary jaw having a lip configured to contact a first major surface of said disk; a registration surface located to contact a second major surface of said disk to position said disk in a desired orientation when said disk is captured between said lip and said registration surface; and a radial control member in contact with said axial opening of said unitary jaw to allow relative movement between said radial control member and said unitary jaw, said radial force control member having a contour such that said radial expansion of said unitary jaw is induced during a portion of movement of said lip toward said registration surface and such that further said radial expansion is avoided in a final portion of said movement of said lip toward said registration surface.
