ABSTRACT:
A lead overlay magnetoresistive sensor has leads with substantially vertical end walls to accentuate sense current near the ends of the leads. Insulating layers isolate the hard bias layers from the path of the sense current. A lead overlay magnetoresistive sensor does not exhibit significant trackwidth widening. A disk drive has a read element including a lead overlay magnetoresistive sensor with leads having substantially vertical end walls.
