Abstract:
A magnetic read head comprising:a spin valve sensor; first and second leads connected to the spin valve sensor; nonmagnetic nonconductive first and second read gap layers; the spin valve sensor and the first and second leads being located between the first and second read gap layers; ferromagnetic first and second shield layers; the first and second read gap layers being located between the first and second shield layers with the first read gap layer interfacing the first shield layer and the second read gap layer interfacing the second shield layer; said second lead layer being electrically connected to the second shield layer; and the second read gap layer extending over an entirety of the first lead layer so as to completely insulate the first lead layer from the second shield layer, and the second read gap layer not extending over at least a portion of the second lead layer so that the second lead layer interfaces the second shield layer for the electrical connection therewith.
