ABSTRACT:
A GMR read head is described. The device comprises a spin valve stack whose top layer is a first capping layer. On the first capping layer are two additional layers, a lead overlay layer and a second capping layer. These are divided into two opposing portions, separated from each other by a trench that is filled with a dielectric. A bias layer and a conductive lead layer contact the stack on its sidewalls.
