摘要： A method for forming a bottom spin valve sensor element with a novel seed layer and synthetic antiferromagnetic pinned layer and the sensor so formed. The novel seed layer comprises an approximately 30 angstrom thick layer of NiCr whose atomic percent of Cr is 31%. On this seed layer there can be formed either a single bottom spin valve read sensor or a symmetric dual spin valve read sensor having synthetic antiferromagnetic pinned layers. An extremely thin (approximately 80 angstroms) MnPt pinning layer can be formed directly on the seed layer and extremely thin pinned and free layers can then subsequently be formed so that the sensors can be used to read recorded media with densities exceeding 60 Gb/in2. Moreover, the high pinning field and optimum magnetostriction produces an extremely robust sensor.

摘要： Head elements are formed on a wafer in order to suppress deterioration in pinning strength of a pinned layer, which is caused by ESD generated during a thin film magnetic head production process, particularly in an air bearing surface polishing step. The wafer is cut line by line into rovers in each of which the head elements are connected; surfaces to be used as air bearing surfaces of the rover are polished until an MR element height reaches to a predetermined value. After this air bearing surface polishing, an electroconductive polishing liquid is used in a final bearing surface polishing step of finishing the air bearing surfaces to achieve a predetermined shape with high accuracy and a predetermined value of a surface roughness. In order to suppress a pinning defect occurrence rate by suppressing deterioration in pinning strength of a pinned layer of a read element, a specific resistance of the electroconductive polishing liquid is controlled to GΩ·cm or less, preferably 1 GΩ·cm or less. After that, a shallow rail and a deep rail are formed on the air bearing surfaces, and the rover is cut to accomplish thin film magnetic heads.

摘要： A nano-sized CPP aperture is precisely positioned to within a few nanometers of a slider ABS surface to maximize a signal from the disk and to prevent lapping damage to the aperture itself. A linear array of apertures is aligned perpendicular to the ABS plane. The head resistance is monitored during lapping. Each time an aperture is lapped through, there is an increase in head resistance that is equal to the inverse of the total aperture area. There are three equal-sized apertures that are evenly spaced apart. When the first aperture is lapped through, there is a 50% increase in resistance, and a 100% increase in resistance when the second aperture is lapped through. These resistance increases are very large and are easy to distinguish from noise.

The leading side rail surfaces include first stepped surfaces having a predetermined height h1 and second stepped surfaces having a predetermined height h2 from the first stepped surfaces, the first stepped surfaces and the second stepped surfaces having continuity in a longitudinal direction of the magnetic head slider.

摘要： Currently, the shield-to-shield separation of a spin valve head cannot be below about 800 Å, mainly due to sensor-to-lead shorting problems. This problem has now been overcome by a manufacturing method that includes inserting a high permeability, high resistivity, thin film shield on the top or bottom (or both) sides of the spin valve sensor. A permeability greater than about 500 is required together with a resistivity about 5 times greater than that of the free layer and an MrT value for the thin film shield that is 4 times greater than that of the free layer.

摘要： A process for fabricating sliders with one or more sacrificial structures (extensions) that facilitate lapping to create the air-bearing surface (ABS) is described. Prior to separating individual sliders from a wafer, a mask of material that is not removable by deep reactive ion etching (DRIE) is patterned on the surface of the sliders. The mask outlines a sacrificial extension around portions of the magnetic transducer elements that are nearest the predetermined plane which will become the ABS. The sacrificial extension makes the surface of the slider which will be lapped non-planar. The sacrificial extension extends below the predetermined ABS plane. When the sliders are individually separated by DRIE, the shape of the mask including the sacrificial extension is projected down into and along the slider body.
