Abstract

PURPOSE: To record and reproduce various information without influencing a servo system, by specifying recording and reproducing methods for control pulses.
CONSTITUTION: To control pulse input terminal 1, rectangular control pulses separated from a composite video signal recorded on a magnetic tape by VTR and then halved in repetitive frequency by a monostable multivibrator are inputted and to input terminals 2 and 3, a signal of level "H" or "L" is inputted corresponding to a stereo sound broadcast signal, duplex sound broadcast signal, television signal, and its recording signal. Then, control signals differing in duty cycle are outputted to output terminal 5 through transistors Tr1 and Tr2 and monostable multivibrator 4 corresponding to various recording signals and then recorded on a recording medium. For reproduction, reproduced signals inputted to input terminal 13 are passed through transistors Tr4WTr6, monostable multivibrators 14W16, capacitors C2 and C3, etc., and only positive-polarity pulses are used as the reference signal of the phase control system of a rotary video head servo system, thereby reproducing information by using negative-polarity pulses.
