Abstract
A disc repair system which is provided for the purpose of consumer-repairing of scratches on optically-read discs (e.g., digitally recorded discs, known commonly, as “CD” discs or “DVD” discs, etc., containing audio or video or other formats of data information), such that an optical reader, which uses a laser to read digital information stored on a compact disc, can read the digital information without the optical distortion caused by a scratch. The system utilizes diamond grit as an abrading compound to recondition the disc surface.
