Abstract:
Apparatus for recording/reproducing a tape, comprising:a recording/reproducing head;a recording/reproducing circuit for connection to one side of the recording/reproducing head and having a voltage generating circuit for generating a reproducing bias voltage;a mode switching circuit for switching between a recording mode and a reproducing mode in response to a mode control voltage applied thereto;signal pass switching means connected to the other side of the recording/reproducing head for controllably connecting the reproducing bias voltage from the voltage generating circuit with the other side of the recording/reproducing head in the reproducing mode in accordance with the mode control voltage from the mode switching circuit and wherein an AC bias recording circuit is also connected to the other side of the recording/reproducing head; andbypass means activated by the mode control voltage and connected to a junction of the signal pass switching means and the voltage generating means to avoid supplying surplus current through the signal pass switching means to the voltage generating circuit in the reproducing mode.
