ABSTRACT:
A method for repairing and refinishing an audio and video compact disk having a scratch or a plurality of scratches on a plastic cover bottom side of the disk. The scratch interfering with a laser beam reading digital information upwardly through the bottom side of the disk. The top side of the disk having a thin film layer of the recorded digital information secured thereon. The interference by the scratch causing an unwelcome "skip" during the play of the disk thereby lending its playing qualities unacceptable. The method of repair includes first inspecting the disk to determine the depth of the scratch. If the scratch is deep, a heavy cut, medium cut and fine cut cleaner may be used. The top side of the disk is then placed against the soft covered wheel and secured thereto. As the disk is spun at low rpm, the heavy cut cleaner is applied evenly across the surface of the bottom side of the disk using a clean cotton cloth or cotton pad. This step is repeated at higher rpm using a medium cut cleaner and then a fine cut cleaner is used. A clear plastic cleaner and a clear plastic polish are then applied using a cotton pad. The disk is then finally inspected for any remaining scratches. To further enhance the repair of the disk and extend the playing life of the disk, a clear plastic cover is applied to the top side of the disk to protect the recorded data thereon from permanent damage.
