Abstract
A video signal speed-change reproducing system reproduces video signals which are recorded by alternately a pair of rotary recording heads mounted on diametrically opposite sides of a rotating member. The video signals are recorded on video tracks disposed contiguously and obliquely relative to the tape longitudinal direction. The recording heads have gaps of mutually different azimuth angles. In the reproducing system, the video signal recorded on the tape is reproduced by means of a pair of reproducing heads for exclusively reproducing which are mounted on diametrically opposed sides of a rotational member. The tape is caused to travel at a speed different from a tape speed for normal reproduction (and recording), or to stop. The reproducing heads have gaps of the same azimuth angle as the azimuth angle of either one of the recording heads.
