Rotary recording medium and reproducing apparatus thereof

A reproducing apparatus for reproducing recorded signals from a rotary recording medium, said rotary recording medium having a spiral track made up of a plurality of track turns on which a video signal, a kick instruction signal, and an audio signal are recorded, said video signal being recorded on the track turns in terms of units and the video signal of an identical unit being repeatedly recorded in one track turn, said kick instruction signal being recorded during vertical blanking intervals of the video signal with a predetermined interval, said audio signal being made up of divided audio signal parts each having a duration of one unit of the video signal, said divided audio signal parts being distributively recorded on the track turns, said reproducing apparatus comprising:

• reproducing means including a reproducing element for scanning over said spiral track on the rotary recording medium and for reproducing the recorded signals from said spiral track, said predetermined period with which said kick instruction signal is recorded on the rotary recording medium being equal to a predetermined number of units of the video signal and being in accordance with the kind of video signal program source from which the video signal is supplied;
• detecting circuit means for detecting said kick instruction signal from among the signals reproduced by said reproducing means;
• kick pulse generator means for generating a kick pulse responsive to the kick instruction signal supplied from said detecting circuit means, said kick pulse causing said reproducing element to shift from one track turn to another track turn, said reproducing element repeatedly scanning over the same track turn during a still picture reproduction mode and scanning over the track turns along a predetermined scanning locus in accordance with the kick pulse during a normal reproduction mode;
• and
• switch means for selectively suppplying the output signal of said detecting circuit means to said kick pulse generator means during a normal reproduction mode, and for supplying a still picture reproduction mode signal to said kick pulse generator means during a still picture reproduction mode,
• said reproducing means reproducing a continuous audio signal as said reproducing element scans over the track turns along the predetermined scanning locus during the normal reproduction mode.
