Biasing circuit for magnetoresistive sensor and magnetoresistive magnetic head/arm electronic circuit

Biasing circuit for magnetoresistive sensor and magnetoresistive magnetic head/arm electronic circuit

A circuit for producing a predetermined effective magnetic bias of the sensor portion having a sensor resistance (RS) of an MR transducer including a sensor lead portion and a front-lead portion having respective lead resistances (RL,RF), by generating a controlled bias current (IB) through the MR t...
