ABSTRACT In an apparatus for controlling a tracking position of magnetic head which reproduces parallel tracks subsequently formed on magnetic tape, the parallel tracks containing a video signal and a pilot signal having mutually different frequencies changing in cyclic sequence from track to track, a pair of control signals are generated in response to amplitudes of the reproduced pilot signal, said pair of control signals being indicative of opposite displacements of the head from the track to be traced, and a tracking error signal is formed by mixture of the pair of control circuits to control the tracking position in response to said tracking error signal. In accordance with this invention, magnitudes of the pair of control signals are independently controlled according to the desired tracking position of the head.
