    摘要： A method is disclosed for fabricating a read head for a magnetic disk drive having a read head sensor and a hard bias layer, where the read head has a shaped junction between the read head sensor and the hard bias layer. The method includes providing a layered wafer stack to be shaped. A single- or multi-layered photoresist mask having no undercut is deposited upon the layered wafer stack to be shaped. The layered wafer stack is shaped by the output of a milling source, where the shaping includes partial milling to within a partial milling range to form a shaped junction. A hard bias layer is then deposited which is in contact with the shaped junction of the wafer stack. A read head and a magnetic hard disk drive having a read head layer stack which has been partially milled are also disclosed.

    摘要： A spin valve sensor includes an antiparallel (AP) pinned layer structure which is self-pinned without the assistance of an antiferromagnetic (AFM) pinning layer. A free layer of the spin valve sensor has first and second wing portions which extend laterally beyond a track width of the spin valve sensor and are exchange coupled to first and second AFM pinning layers. Magnetic moments of the wing portions of the free layer are pinned parallel to the ABS and parallel to major planes of the layers of the sensor for magnetically stabilizing the central portion of the free layer which is located within the track width.

    摘要： A method of making a nickel iron (NiFe) layer and a cobalt or cobalt based layer of a free layer structure forms the cobalt or cobalt based layer by oblique ion beam sputter deposition with the cobalt or cobalt based layer located between the nickel iron (NiFe) layer and a copper (Cu) spacer layer of a spin valve sensor for reducing hard axis coercivity HCH which increases sensitivity and magnetic stability of a magnetic read head. An alpha iron oxide (&agr;FeO) layer on a nickel oxide (NiO) layer of a pinning layer may also be obliquely ion beam sputtered for improving magnetic stability of the read head.

    摘要： A pinning layer structure is provided for a spin valve sensor of a read head which has a reactively deposited nickel oxide first film which underlies a reactively sputter deposited second film of iron oxide (Fe2O3) or (Fe3O4). In the preferred embodiment the pinning layer is composed of cobalt (Co) or cobalt iron (CoFe) which is exchange coupled to the iron oxide (Fe2O3) or (Fe3O4) second film of the pinning layer. This structure results in an improved magnetoresistive coefficient (dr/R) which is substantially maintained after annealing so that the magnetic head has good thermal stability when subjected to high temperatures in the presence of a field that is antiparallel to the pinned orientation of the magnetic moment of the pinned layer.
