Abstract
A disc repair system embodied by a consumer kit, 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, 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 consumer kit (in a special box package) contains a hand-held rotator which is preferably used in combination with abrading compounds, abrasive discs, and wiping cloths to recondition the disc surface.
