disc repair

disc repair

The removal of fingerprints and scratches from the non-label side of CDs and DVDs. Although lasers can read a disc with minor scratches, heavy scratches will cause read errors. The lowest-end repair kits provide a bottle of liquid and hand wipes for removing minor scratches. Consumer machines are widely available that buff the disc surface, while high-end prosumer and commercial machines resurface the disc by sanding or reshaping. See also data recovery.

The Dry Approach
Used by prosumers and disc rental organizations, this Venmill Skip-Away heats the disc to a temperature that enables a buffing wheel to reshape the surface without removing any material. Venmill also makes higher-speed commercial models for continuous use, and all units employ the reshaping method.
