ABSTRACT:
A record mark is formed on a master disc DS. The record mark is formed substantially along a spiral standard locus, but a record mark position is displaced in a direction crossing the spiral standard locus according to record data. A wobble is formed such that the average value of the displacement of the record mark position is zero for each predetermined data unit with the standard locus as a reference.
