Top formed grating stabilizer

摘要

A magneto-resistive sensor head and a method of manufacturing the magneto-resistive sensor head. The magneto-resistive sensor head includes a first lead and a second lead. A magneto-resistive layer and a biasing layer are disposed between the first lead and the second lead. A grating is disposed in the magneto-resistive layer. The topography of the biasing layer is unaffected by the presence of the grating.
