ABSTRACT:
A magnetoresistive sensor has bias magnets with substantially vertical end walls. The offset between the bias magnets and the free layer is optimized by adjusting the thickness of a spacer layer. A disk drive has a read element including a magnetoresistive sensor with optimized bias magnets having substantially vertical end walls.
