Abstract

A clamp for mounting an information storage disk on a hub or spindle includes an annular member which surrounds the hub and has fingers which exert outward radial forces on the inside edge of the disk. A series of L-shaped legs also extend from the annular member and impose axial forces on a flat surface of the disk, the total axial force being smaller than the sum of the radial forces. The clamp is made of a spring-like material and is held in place by a series of inwardly extending nubs which make contact with the hub.
