Recording/reproducing apparatus and tracking servo control method

A recording/reproducing apparatus comprising:

• a rotary-type magnetic recording medium including a track pattern in which concentric or spiral data recording tracks are provided;
• a composite magnetic head including a reproducing element that carries out a read of a magnetic signal from the magnetic recording medium and a recording element that carries out a write of a magnetic signal on the magnetic recording medium;
• a control unit that moves the magnetic head over the magnetic recording medium to carry out tracking servo control on one element out of the reproducing element and the recording element to keep the one element on one of the data recording tracks;
• and
• a storage unit that stores offset information capable of specifying an offset for calculating an adjustment used to adjust a head position of the magnetic head during the tracking servo control,
• wherein the storage unit stores information that specifies at least two different offsets per revolution of the data recording tracks as the offset information, and
• during the tracking servo control on the one element, the control unit adjusts the head position by changing the adjustment at least once per revolution of the magnetic recording medium in accordance with offsets specified based on the offset information.
