发明名称 ROTARY RECORDING MEDIUM AND REPRODUCING APPARATUS THEREFORE
摘要 A rotary recording medium comprises a video signal of the same unit repeatedly recorded for N-field period (N is a natural number greater than or equal to 2) for each track turn, a track shift address signal for instructing the existence of forced track shift of a pickup reproducing element, the shifting direction, and the shifting position, recorded on at least one position for one revolution of the rotary recording medium with a constant period regardless of the kind of video signal source of the video signal, where the track shift address signal comprising at least a synchronizing code, rotary recording medium type discriminating code, a kick existence instructing code, and a kick direction instructing code, and divided audio signal parts obtained by dividing an audio signal for every field period of the video signal which is reproduced, successively arranged and recorded according to a scanning locus of the pickup reproducing element upon normal reproduction. The rotary recording medium has track parts recorded with the divided audio signal parts on at least one part of a recording surface thereof. The reproducing apparatus comprises an address signal reproducing circuit for reproducing the track shift address signal from within a signal reproduced by a reproducing circuit, and a kick pulse generator responsive to an output signal of the address signal reproducing circuit, for generating a pulse for forcibly shifting the scanning track of the pickup reproducing element.
