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...
[ What is claimed is:] [1.] A thin film magnetic head comprising:a magnetoresistive read transducer having first and second contact regions spaced by an active region;first and second electrical leads connected respectively to said first and second contact regions for directing bias current to said transducer; andthird and fourth electrical leads connected respectively to said first and second contact regions for simultaneously detecting magnetic flux representative of recorded signals and directing the detected signal to an output circuit, wherein said ...
