    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： A writer for high frequency, data storage heads. The writer includes a first magnetic pole upon which a write gap pedestal is formed with an upper pedestal layer of high moment material with a planar upper surface. An electrical coil is formed on the first magnetic pole. A write gap layer is deposited on the upper surface of the upper pedestal layer. The writer includes a second magnetic pole disposed above the first magnetic pole with a magnetic, flat, top pole layer. The second magnetic pole includes a bottom shaper fabricated from high moment material positioned between the coil and the top pole layer. An insulation insert separates the bottom shaper from the upper pedestal layer. The second magnetic pole includes a thin dielectric lamination layer that separates the top pole layer from the bottom shaper to disrupt the path of eddy current in the second magnetic pole.

    摘要： In one aspect, a laminated structure including a first plurality of layers containing primarily-iron FeCoN interleaved with a second plurality of layers containing primarily iron FeNi is disclosed. The structure has an easy axis of magnetization and a hard axis of magnetization, has a magnetic saturation of at least about twenty-three-thousand Gauss, and has a magnetic coercivity measured substantially along its hard axis of magnetization that is less than two Oersted. Additional elements can be added in minority concentrations to form primarily-iron FeCoN layers with increased resistivity. The laminated structure has applicability in various fields in which high saturation magnetization, magnetically soft materials are advantageous, particularly for inductive heads.
