A magnetic recording and reproducing apparatus of the helical scanning type, such as a videotape recorder and a DAT (Digital Audio Tape Recorder), in which a magnetic head is controlled so as to move perpendicularly to its scanning direction to fit the undulation of a recording track. For this controlled movement, the apparatus includes a reference signal storage for storing a head displacement signal, which is outputted from a head-moving signal operating unit, as a reference signal for the next scanning operation. With this arrangement, control of the movement of the magnetic head for every recording track is possible to correct a displacement about a position of a magnetic head based on the reference signal, thus increasing convergence of displacement.
