Abstract

PURPOSE:To always scan a luminous point at a constant speed, by recording not only a picture signal but also a signal having a constant frequency. CONSTITUTION:A television signal outputted from a signal source 6 of the television signal is converted to an FM signal by an FM modulator 7, and is applied to one input terminal of an analog switch 8. To the other input terminal of the analog switch 8, a CW signal of an oscillator is applied. On the other hand, the television signal is inputted to a vertical synchronization separating circuit 10, too, a vertical synchronizing signal is separated and outputted, and is applied to a switching signal input terminal of the analog switch 8. As a result, to an output terminal of the analog switch 8, the CW signal and the FM signal are outputted in the vertical synchronizing period and in other period, respectively.
