发明名称 DIGITAL SIGNAL RECORDING APPARATUS
摘要 The present invention is concerned with a signal recording device adapted for recording signals on a recording medium in the form of pulse train recording by a rotating magnetic head. As the magnetic head is performing a recording operation, an erasure magnetic head formed in one piece with the magnetic head performs an erasure operation during the reference level period of the pulse train recording to achieve an optimum signal recording with a lesser power consumption.
