摘要：
A method for forming a top spin-valve SyAP GMR read sensor having a novel conductive lead overlay configuration and the sensor so formed. The lead overlay electrically contacts the sensor at a position within the SyAP pinned layer, thus simultaneously assuring improved electrical contact and destroying the GMR properties of the sensor at the junction to improve the definition of the sensor track width.
