摘要： A magnetoresistive sensor having a self biased free layer. The free layer is constructed upon an underlayer that has been treated by a surface texturing process that configures the underlayer with an anisotropic roughness that induces a magnetic anisotropy in the free layer. The treated layer underlying the free layer can be a spacer layer sandwiched between the free layer and pinned layer or can be a separate underlayer formed opposite the spacer layer. Alternatively, the texturing of an underlayer can be used to induce a magnetic anisotropy in a bias layer that is separated from the free layer by an orthogonal coupling layer. This self biasing of the free layer induced by texturing can also be used in conjunction with biasing from a hard-bias structure.

摘要： During fabrication of a perpendicular write head in a wafer, at least two sides of a write pole are defined (e.g. by ion milling) while a third side of the write pole is protected by a masking material. At this stage, a material that is to be located in the write gap is already present between the write pole and the masking material. After definition of the write pole surfaces, a layer of dielectric material is deposited. During this deposition, the masking material is still present. Thereafter, the masking material (and any dielectric material thereon) is removed, to form a hole in the dielectric material. Next, a trailing shield is formed in the structure, so that at least one portion of the trailing shield is located in the hole, and another portion of the trailing shield is located over the dielectric material, in an area adjacent to the hole. Note that the gap material is now sandwiched between the portion of the trailing shield in the hole, and the write pole.

摘要： An electroplated film is deposited over a substrate with a plating frame pattern that includes a plating field defined by a plurality of individual features. By dividing the plating field into a plurality of individual features, the delamination force at any location on the plating field is greatly reduced. Thus, a film with a large stress, such as a high moment film, may be plated to a greater thickness than is possible with conventionally plated films.

摘要： A method is presented for fabrication of a tape medium read head having a unitary formation of multiple elements for reading multi-track data from a magnetic tape. The method includes providing a continuous substrate layer, and forming a sensor material layer on the continuous substrate layer. Photoresist material is deposited on the sensor material layer, and is patterned to form masks which provide protected areas and exposed areas of the sensor material layer. Exposed areas of the sensor material layer are shaped to form sensors from the protected areas of the sensor material layer. Electrical lead materials are deposited between and adjacent to the sensors, and the masks are removed.

摘要： UV molding from elastomeric masters on thin bendable backplanes that allow replication of UV-cured resist patterns with high accuracy is disclosed. This design accommodates large substrate topographies, has improved de-molding properties, and facilitates two-in-one lithography and assembly of the sliders on topographically structured elastomeric sticky pads. The combination of sticky pad assembly and two-in-one lithography allows an all-in-one harmony process based on UV-molding. These features cure prior art technical problems of the harmony process while significantly reducing cost.
