发明名称 Method of digital signal recording.
摘要 <p>In the first method, a specific section provided in a track is set in DC free state, and when 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. In the second method, a pilot tone is generated only in a specific section provided in the track, and when reproducing, accurate tracking is conducted on the basis of the crosstalk of the pilot tone in the tracks adjacent to this section. As a result, the quantity of redundancy required for tracking is notably reduced.</p>
