Abstract
An apparatus for recording and reproducing a video signal in successive parallel track sections on a moving recording medium includes a rotary head assembly having a movable recording-reproducing head whose tracking position can be adjusted in the direction transverse to the length of the track sections, and a fixed auxiliary reproducing head which is in a following position in respect to the movable recording-reproducing head. During recording, the transverse position of the movable recording-reproducing head is corrected on the basis of the reproduced output of the fixed auxiliary head so as to be eventually in alignment with the path scanned by the latter.
