ABSTRACT:
A rigid disk finishing apparatus characterized by an eccentric spindle of small diameter engaging the inner circumference of a rigid disk; a drive mechanism engaging the outer circumference of the rigid disk to rotate the disk around an axis parallel to but not coaxial with the spindle; and a finishing mechanism which extends fully between the inner circumference and the outer circumference of the rigid disk. A transport mechanism is provided to move an unfinished rigid disk to a finishing station for processing, and to remove a finished disk from the finishing station. The finishing mechanism includes an elongated, abrasive or cleaning tape which can be looped against itself to remove large particles prior to its contact with the rigid disk.
