Abstract

PURPOSE:To realize slow motion reproduction with no noise nor screen fluctuation, by using a triangular wave synchronous with the rotation of a rotor for the driving signal waveform of a head moving mechanism. CONSTITUTION:The drum pulse (a) supplied from a drum pickup head 23 is turned into a rectangular wave (b) through a switching control circuit 24 and then receives a phase control 25. The signal synchronous with the rotary phase is converted into a triangular wave (d) by an integral network 26 to be supplied to a differential amplifier 29 via an amplitude control circuit 27 and an amplifier 28. On the other hand, a control pulse is reproduced (f) by a control head 30 to receive a waveform shaping (g) through a waveform shaping circuit 31 and then applied to a flip-flop 37 after a differentiation 35 through a phase circuit 32. The output signal of the flip-flop 37 is extracted in the form of a trapezoidal wave S out of an FET57 and through the monostable multivibrators 41, 42 and others. This output is supplied to the amplifier 29 to receive an operation with the preceding output (e), and this output (u) is supplied to a heat moving mechanism to be used as a driving signal to give a displacement to a rotary head.
