Abstract
An automatic system for repairing scratches on optically-read discs, (e.g., compact discs often called “CD's” or DVD's). More specifically, an automatic system for refurbishing a plurality of disc surfaces at substantially the same time, such that when refurbished, an optical reader, which uses a laser to read digital information stored on such a disc, can read the digital information on the disc without the optical distortion caused by a scratch.
