A common specific frequency component removal filter connected between the circuits, separate operation switches for controlling operation and non-operation of the pair of recording/reproduction noise reduction circuits, and operation and non-operation of the above-mentioned specific frequency component removal filters. and a control circuit for controlling at least one of the pair of recording and reproduction noise reduction circuits, based on whether the pair of recording and reproduction noise reduction circuits are in operation or not and the recording and reproduction mode. The tape recorder is configured to control the specific frequency component removal filter so that the specific frequency removal filter is activated only when the tape recorder is in the recording state and in the operating state.
