摘要： The present invention provides a magnetoresistive head wherein: a magnetoresistive film is created in a read-track region at the center of the magnetoresistive head; an antiferromagnetic film and a ferromagnetic film experiencing an exchange coupling magnetic field due to direct contact with the antiferromagnetic film are created on each end of the magnetoresistive film outside the read-track region in such a way that the ferromagnetic film is located beside the magnetoresistive film; a nonmagnetic intermediate film is created between the magnetoresistive film and the ferromagnetic film for preventing ferromagnetic coupling from being developed on a contact boundary surface between the magnetoresistive film and the ferromagnetic film and for making crystal orientations of the antiferromagnetic film and the ferromagnetic film uniform; and bias magnetization is applied to the magnetoresistive film by exchange coupling between the antiferromagnetic film and the ferromagnetic film.

摘要： The pinned magnetic layer 2 is composed of a track width region 2' and a dead region 2", the track width region 2' being formed at a spaced apart relation to the bias region 5. Accordingly, magnetization of the track width region 2' is not so strongly affected by the bias region 5, thereby magnetization is fixed along the Y-direction at almost entire region of the track width region 2'. Therefore, the track width region 2' and the free magnetic region are in a crossing relation with each other giving a proper asymmetry in the entire region of the track width region 2'.

摘要： A longitudinal bias layer is laminated above a free magnetic layer with a nonmagnetic layer provided therebetween so that the magnetization direction of the free magnetic layer is oriented by RKKY interaction with the longitudinal bias layer. The RKKY interaction exerts only between the longitudinal bias layer and the regions of the free magnetic layer which are located directly below both ends D of the longitudinal bias layer. Therefore, a thin film magnetic element can be provided, in which the width dimension of a recess formed in the longitudinal bias layer coincides with the magnetic track width.

摘要： In a magnetoresistive magnetic head having a laminate composed of a magnetoresistive (MR) layer showing the magnetoresistive effect, a SHUNT layer as a non-magnetic layer and a soft adjacent layer (SAL) for applying a transverse bias magnetic field to the MR layer, the MR layer and the SAL are made of the same Ni.sub.81 Fe.sub.19 magnetic film. Since the SAL is magnetically saturated in the same direction as the direction of leakage flux of a recording medium (y direction), permeability thereof in the y direction decreases, and the MR effect function therein can be restricted. Although the MR layer and the SAL have the same specific resistance .rho., a sufficient detection current can be made to flow through the MR layer and a high-precision magnetic detection output can be obtained by making the MR layer thicker than the SAL.
