ABSTRACT:
In an apparatus which reproduces video signals from oblique tracks successively formed on a tape, there are provided at least two main rotary heads having different azimuth angles with respect to each other an auxiliary rotary head having the same azimuth angle as that of one of the main rotary heads and which is disposed to substantially scan the same track as that scanned by the one of the main rotary heads. A tape driving circuit for slow motion reproduction of the recorded video signals in which the tape is intermittently driven by an amount corresponding to a predetermined number of the tracks during each of a plurality of predetermined time intervals, and a head control circuit for controlling the operation of the main rotary heads and the auxiliary head in response to the tape driving circuit and head change-over pulses such that when the tape is stopped, the video signals are alternately reproduced by the one of the main rotary heads and the auxiliary rotary head, and the video signals are alternately reproduced by the two main rotary heads during movement of the tape.
