Digital signal recording method

摘要

A specific section provided in a track is set in a DC free state, and during reproducing, accurate tracking is conducted on the basis of the crosstalk from the pilot tone superposed in the adjacent tracks in this DC free section. Alternatively, a pilot tone is generated only in a specific section provided in the track, and when reproducing, accurate tracking is effected on the basis of the crosstalk of the pilot tone in the tracks adjacent to this section. As a result, the redundancy required for tracking is notably reduced.
