Abstract
A video signal reproducing apparatus comprising an integrating drive circuit for controlling the position of a rotary magnetic reproducing head in the traverse direction of a skew recorded track formed on a magnetic tape, a trace control circuit for supplying a jump signal to the drive circuit which causes the magnetic head to jump to the beginning of a track to be traced next on completion of each tracing, a memory for storing the output signal from the magnetic head corresponding to at least one track tracing, and a memory reading and writing control circuit for writing the head output signal into the memory only when the jump signal is absent during slow-motion or still-picture reproduction, and for reading the stored head output out of the memory repetitively.
