Apparatus for repairing the surface of an optical disc

An apparatus for repairing the surface of a optical disc, which is used to repair a damaged area of a laser transparent layer of the optical disc, the apparatus comprising:

• (a) a base seat having a first central line;
• (b) a rotary seat having a disc rest face for a optical disc to rest thereon, the rotary seat is rotatably disposed on the base seat with the first central line of the base seat normal to the disc rest face of the rotary seat, the rotary seat being supported by the base seat to rotate about the first central line thereof;
• (c) an upper cover one side of which is pivotally connected with the rim of the base seat as a first pivot side, whereby the upper cover can be closed and mated with the base seat to cover the same;
• (d) a buffing roller having a second central line and a buffing layer around the surface of the buffing roller, the buffing layer being centered at the second central line, the buffing roller being rotatably disposed on inner side of the upper cover with the second central line passing over the disc rest face of the rotary seat, whereby when the upper cover is closed to cover the base seat, the buffing layer of the buffing roller contacts with and passes over the annular laser transparent layer of the disc;
• and
• (e) a driving mechanism mounted between the rotary seat and the buffing roller for simultaneously rotating the rotary seat and the buffing roller, whereby when rotating, the buffing roller buffs the surface of the laser transparent layer of the disc and at the same time, the rotary seat is driven to rotate, making the disc rested on the disc rest face of the rotary seat rotate about the first central line of the base seat.
