ABSTRACT:
A tracking control apparatus is capable of decreasing sufficiently the effects of crosstalks in effectively utilizing the azimuth angle by tracking controlling the magnetic head in order that the scanning position of the magnetic head will be deviated to the prescribed direction and quantity. In case of tracking controlling the magnetic head depending upon the first and second error signals formed in order to correspond to the frequency difference element between the pilot signal of the adjacent recording track and the pilot signal of the scanning recording track, since the first and second error signals are to be weighted with the prescribed ratio, the scanning position of the magnetic head can be deviated to the position where the crosstalk of the reproducing signals can be sufficiently decreased for practical use.
