ABSTRACT:
A method for repairing a compact disc (1) damaged by a circumferential scratch (2) comprises subjecting a localized area (21) around the scratch (2) to a treatment regime comprising fifty rubbing cycles with a first abrasive sheet (10) of abrasive particle size of 1 micron. Each rubbing cycle comprises one manual radial stroke in the radial direction A and a return radial stroke in the radial direction B. After the first treatment regime if the scratch (2) has not been sufficiently removed the localized area (21) is then subjected to a similar treatment regime with a second abrasive sheet of abrasive particle size 3 microns. A further similar treatment regime is carried out using a third abrasive sheet of abrasive particle size 5 microns in the event that the second abrasive sheet did not sufficiently remove the scratch (2). On the scratch (2) being sufficiently removed, the localized area (21) is sequentially subjected to further treatment regimes with abrasive sheets of decreasing order of coarseness for removing scratches from previous treatments. A mask (20) having an opening (22) therein is placed on the compact disc (1) for defining and exposing the localized area (21).
