摘要： A magnetic sensor is provided, having two bias layers separated by a decoupling layer to eliminate exchange coupling between the bias layers. The two bias layers may have differing coercivities, such that the biases provided by the bias layers to the free layer are independently adjustable. The grain structures of the two bias layers may be substantially decorrelated by the decoupling layer.

摘要： A method for fabricating a read head sensor for a magnetic disk drive is presented. The method includes providing a layered wafer stack to be shaped, where the layered wafer stack includes a free layer, a barrier layer and a pinned layer. A single- or multi-layered photoresist mask is formed upon the layered wafer stack to be shaped. A material removal source is provided and used to perform a partial depth material removal within a partial depth material removal range which extends from the free layer to within the pinned layer to a partial depth material removal endpoint. In various embodiments, this depth endpoint lies at or within the barrier layer or within but not through the pinned layer.

摘要： A process is described for fabricating sliders with reduced lapping damage to the hard-bias materials. The stack of layers for the magnetic sensor is deposited on a wafer and patterned into an initial shape. The hard-bias structures are fabricated at the side of the magnetic sensor as in the prior art. In each of the two described embodiments of the invention, the hard-bias material below the ABS is reduced or removed and replaced with a fill material such as alumina. A first embodiment reduces the hard-bias material below the ABS by forming an extended lapping gap along the ABS in both the sensor and hard-bias material. A second embodiment forms a photoresist mask over the sensor and the portion of the hard-bias/lead structures above the ABS and the exposed hard-bias/lead material below the ABS is thinned or completely removed by milling.

摘要： A magnetic head has highly thermally conductive insulator materials containing cobalt-oxide so that heat can more effectively dissipate from the magnetic head. In one illustrative example, the magnetic head has first and second gap layers and a read sensor disposed between the first and the second gap layers. The first and the second gap layers are advantageously made of cobalt-oxide (CoOx) (e.g. CoO or Co2O3), which may exhibit a thermal conductivity of between 5-8 watts/meter-Kelvin or greater. In another illustrative example, a magnetic head is made of a substrate; first and second shield layers; an undercoat layer formed between the substrate and the first shield layer; first and second gap layers formed between the first and the second shield layers; and a read sensor formed between the first and the second gap layers. The undercoat layer is also made of CoOx. The improved dissipation of heat from the magnetic head improves the read sensor performance and reduces the likelihood of other problems, such as head-to-disk interface problems.
