Abstract

PURPOSE:To obtain a slow motion reproducing picture, by feeding magnetic tape intermittently by one track pitch, and making the switching of each head of the 1st and 2nd rotating head pairs according to the output signal of the 1st and 2nd control signal reproducing heads. CONSTITUTION:A head switching pulse A is inputted from a terminal 11, and an intermittent drive pulse (b) is formed via monostable multi-vibrators 12, 13. The pulse (b) is applied to a drive circuit 14, where a capstan motor 15 is driven intermittently. On the other hand, the pulse A is applied to a differentiation circuit 30 and applied to gates 28, 29 via an inverter. Gate pulses (h) and (i) are given to the gate circuits 28, 29 to form differentiation pulses (j) and (k). The pulses (j) and (k) are applied to a F/F32 to form head switching pulse (l). In case of slow playback mode, (m) is at high level, and the inversion (l) signal is applied to a selector switch 35 and the (l) signal is to the selector switch 38 respectively. When the (l) is at high level, the switch 38 is selected to H side and the switch 35 is to L side to select heads A and A'.
