ABSTRACT:
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 reproducing 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.
