US Patent:

6780090, Aug 24, 2004

Filed:

Nov 21, 2001

Appl. No.:

09/990152

Inventors:

Michael S. Kennedy - Peoria AZ 85381
Justin R. Hastings - Kansas City MO 64131

International Classification:

B24B 100

US Classification:

451 41, 451 59, 451 63, 451287, 451290

Abstract:

An apparatus and method for re-surfacing compact discs. The 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.
