Repair and polishing of an optical disc uses drive units that carry repair discs that are rotated against the optical discs

摘要

The cleaning or repair of the surface of an optical element uses repair elements [5] that are rotated. The elements are mounted on a base in a housing. The repair disc is mounted on a carrier [4] that fits on a coupling disc [3]. This is spring loaded [2] against a drive sprocket [1] that has a coupling gear [12] to a motor.
