ABSTRACT:
A recording/reproducing circuit according to the present invention comprises a recording amplifier for outputting a recording signal, a differential amplifier including a pair of transistors, a base of one of the transistors being a (+) side input, a base of the other transistor being a (-) side input, emitters of the transistors being connected commonly to a current source, the (+) side input being supplied with the recording signal, an output signal being fedback to the (-) side input, the output signal being sent to a recording head and means for cutting a current of the current source to thereby stop an outputting of the recording signal from the differential amplifier circuit.
