ABSTRACT:
In an apparatus for reproducing video or other information signals recorded in successive parallel tracks extending obliquely on a magnetic tape or other record medium which is adapted to be longitudinally advanced, and in which a magnetic head or transducer is movable in the direction generally along the tracks for reproducing the signals recorded therein and is mounted or supported by a bi-morph leaf or other transducer deflecting device which is operative, in response to the reception of an electrical drive signal, for deflecting the transducer or head in a direction transverse to the direction along the tracks, a head movement detector is attached to the transducer deflecting device for providing a head movement signal in correspondence to deflections of the head in said transverse direction, a dithering signal or oscillation is included in the drive signal along with a head position and track selection control signal, and the envelope of the signals reproduced by the head is synchronously detected for generating a track following error signal which is also included in the drive signal; such synchronous detecting of the reproduced signal envelope is effected with the head movement signal from which there has been eliminated at least the head position and track selection control signal, for example, by subtracting the latter from the output of the head movement detector.
