ABSTRACT:
A method of one embodiment of the invention is disclosed that generates a non-Cartesian coordinate system for an optical disc. One or more uniform distances, as well as a plurality of positions on the optical disc, are selected. Each position is separated from adjacent positions by one of the uniform distances, and has a location on the optical disc specifiable to a same degree of precision by at least one integral coordinate.
