US Patent 7283148 Optically marking the label side of an optical disc

A method for labeling an optically writable label side of an optical disc of an embodiment of the invention rotates the optical disc such that an optical marking mechanism passes adjacent to a track of the optically writable label side of the optical disc a number of times greater than one. During each pass adjacent to the track by the optical marking mechanism, the optical marking mechanism writes a mark at each desired position of a plurality of positions. Each desired position of the plurality of positions has a same number of marks written thereto by the optical marking mechanism equal to the number of times the optical marking mechanism passes adjacent to the track.
