ABSTRACT:
A read/write amplifier provides a magnetic disk unit capable of reducing variations of the bias voltage. An output stage provides a DC bias circuit for the read signal and a circuit for producing a high impedance for the read signal. A switch circuit is in a closed circuit operation only when a chip select signal is received. The output stage provides a switching order to connect a constant current circuit to the amplifier circuit at read time and to connect the DC bias circuit at the write time.
