Abstract
The present invention provides a system for cleaning and polishing an optical disk. The system comprises a tray having a circular floor and a parameter wall; an armature having at least two circular pads being rotatably coupled to the armature; and a mechanism for rotating the armature parallel to the floor and about a central axis of the wall being perpendicular to the floor. The mechanism rotates the armature in a first direction, which in turn rotates each pad in a second direction to clean and polish the optical disk.
