ABSTRACT:
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.
