Method and apparatus for recording track numbers in a standard recording mode and a long time recording mode

摘要

When a ratio of track pitches in an SP mode and an LP mode is equal to 3:2 the track number is recorded onto each track by advancing the track number one by one in the SP mode and the track number is advanced by setting the even or odd track numbers as a same track number in two tracks and is recorded onto each track in the LP mode. Thus, even when a new recording is performed onto a recorded tape, the track numbers are continuous, so that the track number can be used for detecting the absolute address.
