As recording density of sensors is increased, it is desired to lower the areal resistivity (RA) of TMR sensors. Decreasing RA to 1.0 Ωμm2 or below badly influences the read signal since the interlayer coupling magnetic field (Hint) between the pinned layer and the free layer increases sharply and impedes the free rotation of magnetization of the free layer. According to one embodiment, a tunnel junction type magneto-resistive head solves this problem by having a layered film comprising an underlying layer, a crystalline orientation control layer, an antiferromagnetic layer, a first ferromagnetic layer, an antiparallel coupling layer, a second ferromagnetic layer, an insulation barrier layer, and a third ferromagnetic layer between a lower magnetic shield layer and an upper magnetic shield layer, wherein a crystallographic plane of the antiferromagnetic layer is directed parallel to a film surface by growing the antiferromagnetic layer substantially conformably on the crystalline orientation control layer.
