ABSTRACT:
A rotary recording medium to be reproduced by a reproducing apparatus having a reproducing element, has a spiral track consisting of plural track turns on which a video signal and an audio signal have been recorded, and a plurality of same units of the video signal are recorded in each of the track turns, and an instruction signal having an information for instructing a shift of the reproducing element from a track to another track turn is recorded in a vertical blanking interval of the video signal with a predetermined field period according to a kind of the video signal program source, where the audio signal consists of divided audio signals in which a continuous audio signal is divided in every interval of field period of the video signal to be reproduced. A reproducing apparatus for reproducing this rotary recording medium comprises a detecting circuit for detecting the instruction signal from among signals reproduced by the reproducing element, a kick pulse generator for generating a kick pulse responsive to the instruction signal supplied from the detecting circuit, and a switch for selectively supplying the output signal of the detecting circuit in a normal reproduction mode and supplying a still picture reproduction mode signal in a still picture reproduction mode to the kick pulse generator.
