Patent ID: 7753762

Claim:
A device for removing an information-bearing layer of an optical disc, which comprises: a housing defining a first chamber and a second chamber; a mount, including a planar surface, to selectively mount an optical disc having an information-bearing layer adjacent the first chamber; a cutter within the first chamber, the cutter comprising at least one cylindrical section with an axis of rotation, a wall disposed about the axis and having a first end and an outwardly oriented second end, and a cutting surface at the second end of the wall for cutting contact with the optical disc, the axis being disposed at an angle of from about 70° to 80° relative to the planar surface; a drive mechanism operatively connected to the cutter for rotating the cutter about its axis; and a passageway between the first and second chambers, wherein the cutter causes the information-bearing layer of the disc to form particulate matter and the particulate matter is caused to move through the passageway into the second chamber.
