Filed: 1984-03-21
Abstract: PURPOSE:To reduce a switching noise of a sound signal by decreasing a recording current of a video signal of the vicinity of a head switching point, or increasing a recording current of a sound signal of a vicinity of the head switching point. CONSTITUTION:An FM-modulated video signal 7 is inputted to a gain switching circuit 1, a vertical synchronizing signal 9 fetched from the signal 7 is inputted to a monostable multivibrator 6, and a signal 10 is outputted. That is to say, the signal 10 which becomes a high level, when a switching signal 12 rises and falls is outputted. Accordingly, a video signal current recorded by a rotary head 3 through an amplifying circuit 2 becomes small. On the other hand, in a period in which the signal 10 is in a low level, the switching circuit 1 becomes a usual gain and the video signal current recorded by the head 3 becomes as usual. In this way, when a ratio of a recording current of a sound signal and a recording current of a video signal is made larger than that of other time than a switching time of a rotary magnetic head, an S/N ratio of the switching time of the rotary magnetic head is improved.
