Abstract: In an apparatus for reproducing video signals recorded in successive parallel tracks extending at an angle to the lengthwise direction of a tape and wherein two main reproducing heads having different azimuth angles with respect to each other are arranged to be diametrically opposed and alternately reproduce the video signals from the tracks when the tape is transported lengthwise at a standard speed, and an auxiliary reproducing head having the same azimuth angle as one of the main reproducing heads is circumferentially displaced by (n+0.25)H' from another of the main reproducing heads where n is zero or a positive integer and H' is an angle corresponding to one horizontal scan line on the tape, from the auxiliary reproducing head and reproduces the video signals in cooperation with one of the main reproducing heads when the tape is stopped and delay control means for alternately delaying the reproduced video signal from one of the main reproducing heads and the video signal from the auxiliary reproducing head by an amount corresponding to a break in the continuity of the horizontal synchronizing pulses which occurs in synchronism with the changing of the reproduction of said video signals by the one of the main reproducing heads and auxiliary reproducing head.

Abstract: In an apparatus which reproduces video signals using rotating heads to scan oblique tracks formed on a tape, the tape is intermittently moved and stopped by a tape capstan motor which is driven by a motor drive pulse. The motor drive pulse is generated at predetermined time intervals corresponding to a predetermined number of tracks for slow-motion reproduction of the recorded video signals. Deviations in the amount of tape intermittently advanced, as measured by a predetermined number of tracks, is avoided by varying the pulse-width or amplitude of the motor drive pulse.

Abstract: In an apparatus which reproduces video signals from oblique tracks successively formed on a tape, the tape is intermittently moved by a tape capstan motor being driven by a motor drive pulse which is generated by an amount corresponding to a predetermined number of said tracks at every predetermined time interval for slowmotion reproduction of the recorded video signals. A pulse-width or amplitude of the motor drive pulse is controlled in accordance with the slow-motion speed.
