Abstract

PURPOSE: To simplify the circuit constitution, by reducing the number of recording reproducing changeover switches and commonly using the amplifier in common use for recording reproducing as microphone amplifier also, in a two-head type magnetic recording reproducing device.
CONSTITUTION: At recording, an input signal is fed to a recording head 4 via impedance element 20 and resistor 19 having reverse characteristic as reproducing equalizer, and via a recording reproducing amplifying circuit 11a having reproducing equalizer characterstic, recording equalizer 15, bias trap 16 and changeover switch 3a. On the other hand, at reproduction, the reproducing head signal is output at an output terminal 14 via the switch 3a, resistor 23, recording reproducing amplifier 1, and reproducing output amplifier 13. At the reproduction as mentioned above, when a microphone signal is fed to an input terminal 5, said recording reproducing amplifier 1 can be used as a microphone amplifier, enabling the mixing between the reproducing signal and microphone.
