    摘要： A head including a write element for writing data to a magnetic media, and methods for its production are provided. A write element of the invention includes one or more of a recessed first pole, a heat sink layer, and a shortened yoke length. A method of the invention provides forming an anti-reflective layer before forming a mask layer. During photolithography the anti-reflective layer suppresses undesirable reflections off of features, such as vertical sidewalls, that otherwise limit how closely to such features portions of the mask layer can be formed.

    摘要： A magnetic sensor is disclosed having a shallow contiguous junction. Such a sensor is can greatly increase yield for mass-produced heads, especially for large wafers. The magnetic bias layers can be aligned with a free layer of the sensor, improving performance. Milling may be terminated prior to penetration of an antiferromagnetic layer, so that for example the antiferromagnetic layer may extend significantly beyond the free and pinned layers of the sensor.

    摘要： An improved method of manufacturing is provided for making an improved merged MR head. The method employs a photoresist mask with appropriately-sized openings for simultaneously etching numerous vias to various depths over a set time period. After formation of the vias, a single photoresist mask is employed to pattern in one step gap layers G3, G2, G1 and a first shield layer S1 to the desired lateral configuration for the merged MR head. Subsequent to patterning these thin film layers, double insulation layers I2 and I3 are individually soft baked on top of the coil structure of the head followed by patterning of the layers I2/I3 by a single photoresist mask. These layers are then hard baked to retain the desired smooth configuration of the layers. The improved merged MR head has a smooth configuration to its top pole piece P2 because of the smooth configuration of the I2/I3 layer so that flux leakage and saturation problems are minimized.

    摘要： An MR read transducer having passive end regions separated by a central active region comprises an MR layer made from a material having a low uniaxial magnetic anisotropy. A soft magnetic bias layer is adjacent to but spaced from the MR layer in the central region only, and the soft magnetic bias layer is made from a material having a high uniaxial magnetic anisotropy. A longitudinal bias is produced directly in each of the end regions only, and the means for producing the longitudinal bias comprise a layer made from a material having a high uniaxial magnetic anisotropy. Control of the uniaxial anisotropy can be achieved by choosing materials of appropriate magnetostriction or intrinsic uniaxial anisotropy.

    摘要： A magnetoresistive (MR) read transducer having passive end regions separated by a central active region in which an MR layer is formed which extends over substantially only the central active region and in which a hard magnetic layer is formed in each end region. The hard magnetic layers form an abutting junction having electrical and magnetic continuity with the MR layer to produce a longitudinal bias in the MR sensor. The transducer is produced by a method in which the same stencil defines the extent of both the MR layer and the hard magnetic layers so that the abutting junctions are formed easily and reliably.
