In such an apparatus, the position adjustment of the upper head (10) is performed by reproducing the position adjustment signal (6) at the upper head (10). In this case the screws (28) (3
0) is loosened so that the elastic plate member (20) moves in the direction parallel to the surface of the magnetic disk (2), and the head support (18) is manually moved in the directions of arrows A, B and ψ. After adjusting the position, the head support (18) is fixed to the reciprocating body (12) by tightening the screws (28) (30) after adjusting the position. In such a conventional method, since it is free in all directions of the planes of the arrows A, B, and ψ, it is very difficult to adjust when moving it by a human hand. In addition, since the pressing force of the upper head (10) is likely to change during the adjustment, there is a drawback that the signal output level is not constant. Therefore, it takes a very long time to adjust the position of the upper head.
