PURPOSE:To realize the postrecording of voice, by providing a track exclusive for voice as well as a fixed magnetic head exclusive for voice. CONSTITUTION:In the postrecording mode of voice, the voice signal separated from the video/voice composite signal is supplied to an adder 38 through an FM demodulator 37. At the same time, the postrecording voice signal PRAU is also supplied to the adder 38. Then the mixing ratio between a voice signal AU before postrecording and the signal PRAU is freely changed by a level controller 39 to be delivered from the adder 38. The output of an adder 40 is supplied to a recording amplifier and a bias adding device 42, and the bias signal is added to the circuit 42 by a bias signal generator 43. The output of the circuit 42 is recorded on a track 51 exclusive for voice on a video tape 45 via an analog switch 46 by a fixed magnetic head 44 exclusive for voice. |
