Abstract

PURPOSE:To rewrite to a control signal having new contents, by switching to a recording state only for 1 horizontal period containing the control signal. CONSTITUTION:A signal on a video tape is reproduced by a video head 20, is amplified 22, is converted to an analog signal by a data signal separating and reproducing circuit 23, also is applied to a synchronizing signal separating and clock signal generating circuit 24, too, and a clock is supplied to the circuit 23 and a control signal generating circuit 29 in order to convert an analog signal and to generate a control signal. A vertical synchronizing signal from the circuit 24 is applied to an FF25, and a Q output of the FF25 is provided to an FF26. Subsequently, by a Q output of the FF26, a switch 21, a switch 28 and a switch 210 are connected to the earth side, the output side of a recording amplifier 211, and the output side of the circuit 29, respectively, a signal from the circuit 29, containing an address signal is FM-modulated by the circuit 211, and its output is recorded on the video tape through the switch 21.
