A cleaning machine for cleaning annular discs is disclosed. Annular discs of rigid or flexible material are designed to receive a magnetic coating capable of operating as a memory for a computer. The cleaning machine uses a spindle that aligns and holds the disc. The spindle rotates and high pressure cleaning fluid simultaneously washes both sides of the disc. In one embodiment the spindle has a conical ferrule made of abrasion-resistant rubber. In another embodiment the spindle includes centrifugally-operable hold down arms that extend from the spindle during rotation to keep the disc on the spindle.

A machine for cleaning a surface of an annular disc having an inner annular surface of a predetermined diameter, comprising: a dispenser for dispensing a stream of cleaning fluid onto one or both surfaces of an annular disc, rotational drive means, a spindle for holding and rotating a disc through a dispensed stream of cleaning fluid, the spindle having one end rotatably fixed to the housing and the other end having a tapered surface configuration with a terminal diameter less than the diameter of the disc and gradually increasing in diameter in the direction of the rotatable end said tapered surface so configured to receive and support a disc along the inner annular surface of the disc, and means carried on the spindle and adapted to impart the rotational movement and to direct at least a portion of the centrifugal force of the rotating spindle toward the disc for holding the disc on the spindle as the disc is rotated, impacted and cleaned with dispensed cleaning fluid.
