Abstract
A collet system for mounting, holding, and rotating a rigid disk is described, the collet system including a collet and an expander, the collet having a base portion and fingers longitudinally extending therefrom, the fingers forming a disk contact ring opposite the base. The disk contact ring is less than the thickness of the disk to allow for full surface texturization of the disk. The disk contact ring is not coplanar with any locus of expansion contact points between the collet fingers and the expander, and is sufficiently distant therefrom such that the outward force exerted on the inner disk surface is determined by a cantilever spring deflection experienced by the fingers. This ensures substantially uniform and repeatable outward forces on the inner surface of the disk regardless of minor surface variations along the locus of expansion contact points.
