ABSTRACT:
The relative height between two sets of magnetic head groups shared for recording and reproduction and mounted on actuators is adjusted at high accuracy, so that a track of a predetermined track width and track pitch can be formed. In a rotary head type magnetic recording/reproduction apparatus including two sets of magnetic head groups AT and BT of one or a plurality of magnetic heads displaceable in the track width direction by actuators 100A and 100B, a signal which becomes the reference for relative height adjustment of the heads is recorded by one of the magnetic head groups. Then, the magnetic tape is rewound, and the run of the magnetic tape is controlled by one of the magnetic head groups. Under this state, the relative height between the two sets of magnetic head groups is detected by the other magnetic head group, whereby the relative height of the two sets of magnetic head groups is adjusted according to that information.
