Abstract:
A thin-film magnetic head comprising:a base material having a planar surface;first and second longitudinal bias layers formed over the planar surface, the first and second bias layers being spaced apart by a predetermined distance;a magnetoresistance effect layer formed over the base material and extending between the first and second bias layers;a non-magnetic layer formed on the magnetoresistance layer;a transverse bias layer formed on the non-magnetic layer;first and second electrode layers formed on the respective first and second longitudinal bias layers, said first and second electrode layers being disposed adjacent respective sides of said magnetoresistance effect, non-magnetic and transverse bias layers; anda tantalum film disposed between the magnetoresistance effect layer and the planar surface of the base material.
