Abstract:
A magnetoresistive read sensor comprising:a first hard-biasing film positioned on a first region and a third region of a gap layer, wherein the first and third regions are separated by a second region;a magnetoresistive element positioned on top of the first hard-biasing film and on top of the second region of the gap layer, thereby forming a first and a second passive region of the sensor separated by an active region;an unetched and unmilled spacer layer positioned on top of the magnetoresistive element, which extends over the active region and the first and second passive regions;an unetched and unmilled soft adjacent layer positioned on top of the spacer material, which extends over the active region and the first and second passive regions, the soft adjacent layer establishing transverse biasing for the magnetoresistive element; anda second hard-biasing film positioned on top of the first and second passive regions.
