摘要： A rotary recording medium reproducing apparatus reproduces a recorded signal from a rotary recording medium by use of a reproducing element. The rotary recording medium is recorded with at least a first carrier signal which is modulated by an information signal having a synchronizing signal of a predetermined frequency. The reproducing apparatus comprises a motor for rotating the rotary recording medium, a reference signal generating circuit for generating a reference signal having a frequency equal to a horizontal scanning frequency of a video signal of a standard television system which is characteristic of the reproducig apparatus and should originally be reproduced, or equal to 1/M (M is an integer) times the above horizontal scanning frequency, a detecting circuit for detecting a signal respective of the rotational speed of the rotary recording medium, and a comparator for comparing the reference signal and the signal respective of the rotational speed of the rotary recording medium, to control the rotational speed of the rotary recording medium by a compared output signal thus obtained, so that the synchronizing signal within the reproduced signal is reproduced at a frequency equal to the horizontal scanning frequency of the above standard television system with which the reproduction should originally be performed.

摘要： In a video recording system the chroma components of a color television signal are applied to a multiplexer where they are interleaved in frequency with each other so that the energy concentration of each chroma component occurs at frequencies interleaved with the frequencies at which the energy concentration of the other chroma component occurs. The interleaved chroma components and the luminance component are supplied respectively to frequency modulators each producing an output having energies distributed over the full range of the passband of the system. The outputs of the modulators are fed to first and second transducers for recording the luminance and chroma components on adjacent tracks of a recording medium.

摘要： A rotary recording medium is repeatedly recorded with a video signal of the same unit for a plurality of field periods in each track turn, and divided audio signal parts obtained by dividing an audio signal in units of field periods of the video signal which is to be reproduced are successively arranged and recorded on a recording track of the video signal according to a tracing locus or a reproducing element on the rotary recording medium upon normal reproduction during which change of track is performed by forcibly shifting the reproducing element at least once or a plurality of times for two revolution periods of the rotary recording medium. A rotary recording medium reproducing apparatus comprises a reproducing circuit for picking up and reproducing recorded signals from the above rotary recording medium, and a shifting circuit applied with a discrimination signal in accordance with the type of the rotary recording medium and a reproduction mode signal in accordance with a reproduction mode, for shifting the tracing locus of the reproducing element so as to reproduce a video signal of video and audio signals of a reproduction mode specified by the reproduction mode signal.
