초록

A magnetic head includes a magnetoresistive read transducer which comprises a central active region and two end regions. Bias current leads are connected respectively to end regions for current biasing of the transducer. Signal sensing leads is also are connected respectively to end regions for directing sensed voltage to a signal amplifier. The bias current and the sensed signal assume separate electrical paths. The current crowding effect in the bias current path does not affect the signal sensing path. Thus the transducer can sense signal with improve...
