  • Patent number: 7104871
    Abstract: An apparatus and method for re-surfacing compact discs. One method is a two-step method in which the disc to be re-surfaced is first placed on a shaft. A resilient pad supports an abrasive medium and is positioned so the abrasive medium overlaps only the protective layer of the CD. The disc and abrasive material are rotated in opposite directions at about the same speed to remove deeper blemishes in a wet operation. Subsequent polishing is accomplished in a similar manner using a polishing compound instead of an abrasive. The re-surfacing and polishing apparatus each have motor driven shafts which are parallel and spaced apart and support the CD and pad in a cabinet. A transparent cover extends across the top of the cabinet. In another embodiment, the resurfacing and polishing is accomplished in a one-step operation in which polishing fluid is applied to a non-abrasive medium is utilized and the fluid is continuously recycled.
