To reproduce a video signal recorded in a plurality of individual inclined tracks on a magnetic tape by a head-wheel, the information content of each television picture is distributed over a plurality of the tracks and the reproduction is effected at a different tape speed from that of recording. Each head at the periphery of the head-wheel is deflectable in a direction perpendicular to the plane in which the head-wheel rotates, and at all times at least two heads are simultaneously in contact with the tape. The deflection of each head is controlled in such manner that at any given time at least one of the two heads in contact with the tape is guided along a recorded track, and reproduced picture information is continuously available in correct sequence by selective switching of the outputs from the magnetic heads.
