Patent ID: 7103962

Claim:
A method for manufacturing thin film head comprising: a first step of stacking an antiferromagnetic layer, a pinned layer, a nonmagnetic conductive layer and a free magnetic layer in order of an upper surface of a lower gap layer formed on a lower magnetic shield layer for providing a magnetoresistive element; a second step of stacking a nonmagnetic layer, a ferromagnetic layer and an antiferromagnetic layer on said free magnetic layer locating at the uppermost stratum of said magnetoresistive element for forming a pair of left and right laminated transverse biasing layers, each consisting of said nonmagnetic layer, said ferromagnetic layer and said antiferromagnetic layer; and a third step for forming a pair of left and right lead layers on said antiferromagnetic layers locating at the uppermost strata of said laminated transverse biasing layers.
