PURPOSE:To obtain a reproducer having an inexpensive insert recording function, by increasing the effect for erase of signals before the insert recording through the increase of a recording current of a luminance FM signal than a normal recording and improving the deterioration in a reproduced screen due to information remained unerase. CONSTITUTION:Each input signal from an FM signal input terminal 1 and a low frequency conversion erase signal input terminal 2 is summed and superimposed at an adder 3. At normal recording, since no signal is inputted to an insert control signal input terminal 6, the position (a) of a switch 5 is selected and the output of the adder 3 is inputted to a recording amplifier 7 as it is. Further, at the insert recording, since a control signal is applied to the terminal 6, the position (b) of the switch 5 is selected and the output of the adder 3 is applied to the recording amplifier 7 via an amplifier 4. This amplifier 4 has several dB of gain, and then, the recording current at the insertion is increased for both luminance and chroma signals, allowing to increase the effect of erase of recording signals. |
