Tracking control apparatus of rotary head type recording unit using
pilot signals of different frequencies and different formats
摘要:
A tracking control apparatus for a rotary head type recording unit having a first rotary head and a second rotary head for forming pairs of slant tracks on a magnetic type, each track having a head entering side tracking region and a head leaving side tracking region. First and second pilot signals of different frequencies are recorded in the head entering and head laving sides tracking region, with the first pilot signal being recorded at a predetermined position on the first track which precedes (in the track direction) the second pilot signal recorded at a predetermined position on the second track adjacent to the first track.
