ABSTRACT:
In a magnetoresistive read/inductive write magnetic transducer, magnetic stability of the magnetoresistive read sensor is improved by reducing the bias current to the magnetoresistive read sensor to a predetermined value during a period when a write current signal is applied to the inductive write head. The reduced bias current is greater than zero, but less than that required for reading data stored in a magnetic storage media. The reduced bias current is about 30% of the full bias current applied during the read operation of the magnetoresistive head.
