  • Write drive with current mirrors which reduce feed-through
    Patent number: 4551772
    Abstract: A write driver circuit for a thin film resistive magnetic head has current mirror transistors connected in parallel with the driver transistors which are in an H-configuration. Two resistors connected across the write head have their junction connected to reference potential to create an artificial center tap. In this manner, equal and opposite voltage excursions are produced on both sides of the write head. The transients which would normally be fed through to the read head because of these voltage excursions are cancelled.
