A method and apparatus for repairing optical discs, wherein the apparatus includes an improved buffing wheel capable of applying a uniform buffing action across the readable surface of an optical disc, and wherein the method includes the step of mechanically buffing the damaged area of a disc with an abrasive means and thereafter buffing the buffed area with a non-abrasive means to remove fine scratches caused by the abrasive means.

[ The invention is hereby claimed as follows:] [1.] The method of repairing a damaged area on the surface of an optical disc, wherein said surface of said disc includes laser-penetrable material and the damaged area is first buffed in a buffing apparatus with at least one abrasive means and then buffed by an apparatus or by hand with at least one non-abrasive means, and wherein the buffing apparatus includes a disc-receiving means and a buffing wheel made of a flexible material and having a hub, a flexible annular outer rim, a plurality of flexible spirally spokes extending between said hub and rim, and an abrasive means around the periphery of said rim, and said non-abrasive means includes a piece of cloth, said method comprising the steps of:mounting the disc in said buffing apparatus in a first plane with said surface of said optical disc being exposed,positioning said buffing wheel in a second plane substantially perpendicular to said first plane and under pressure against said surface, whereby said spirally extending flexible spokes of said buffing wheel and said rim are deformed so that the rim defines a flattened portion in engagement with said disc surface and facilitates a substantially uniform pressure along the area of contact between said buffing wheel and said surface,rotating said buffing wheel such that the abrasive means on the rim removes material from said surface and leaves behind fine scratches,moving said cloth under pressure over the area buffed by the apparatus, whereby the action created between said cloth and said surface generates sufficient heat that causes said laser-penetrable material of said surface to flow, smooth the surface, and substantially remove said fine scratches.
