Abstract
PURPOSE: To facilitate adjustment, by providing the first switch circuit between the output terminal of a recording amplifier and the earth point, and also providing the second switch circuit at the input point of a reproducing amplifier and further the third switch circuit which operates a high frequency oscillator for bias only for recording.
CONSTITUTION: For reproducing, the H voltage is supplied to control terminal 6a, and the first switch circuit 6 is turned on, and the output voltage of inverter 12 becomes the L voltage, and therefore, the second and the third switch circuits 10 and 11 are turned off, and the reproducing operation is performed by magnetic head 2. Meanwhile, for recording, the L voltage is supplied to control terminal 6a, and the first switch circuit 6 is turned off, and high frequency oscillator 5 for bias oscillator 5 for bias oscillates, and the second switch circuit 10 is turned on. The output of recording amplifier 4 is connected to the second terminal of magnetic head 2, and the first terminal is grounded through the second switch circuit 10, and the recording operation is performed.
