ABSTRACT:
A magnetoresistive sensor having bias stabilization tabs includes a protective cap layer. The protective cap layer prevents oxidation, avoids potential damage from using ion milling for oxidation removal, and lowers parasitic resistance. In one embodiment, a bias layer, having a central portion with quenched magnetic moment, is formed over the free layer with an intervening coupling layer. A disk drive is provided with the magnetoresistive sensor including a protective cap layer.
