摘要： A reader formed in a data transducer includes a first shield, a read gap, a second shield, a maanetic compensation layer, and a non-magnetic spacer layer. The first shield is formed of a multilayer comprised of a layer of a first material. The second shield is spaced apart from the first shield by the read gap. The magnetic compensation layer is formed in the first shield and has a coefficient of thermal expansion of less than the coefficient of thermal expansion of the first material. The non-magnetic spacer layer separates the first material layer and the compensation layer of the first shield.

摘要： Increases in the AP1 and AP2 thickness cause the free layer to be off-center in a CPP magnetic read head. This problem has been overcome by inserting supplementary magnetic shields within the spin valve, located as close as possible to the stack. These supplementary shields enable the read gap width to be reduced by about 430 Å and the free layer to shift back towards the center by about 30 Å.

摘要： An apparatus and method for lapping and fabricating a read/write head is described. The lapping method includes performing a first lapping process on a structure having the read/write head fabricated therein. The first lapping process is for reducing a first resistive region. The first resistive region is located proximal to a surface of the structure. The first lapping process is for achieving a first lapping benchmark. The lapping method further includes performing a second lapping process on a second resistive region. The second lapping process laps at a rate lesser than the first lapping process. The second lapping process is for achieving a second lapping benchmark. The second resistive region is interposed between the first resistive region and the read/write head. The second resistive region has a different resistive value than the second resistive region.

摘要： A magnetic head is composed to diminish disordered writing bits of a recording layer or reading noise caused by a magnetic field generated from an under layer without decreasing a writing magnetic field strength of the magnetic head. The magnetic head includes a write head provided with a main pole and one or more auxiliary poles, a read head provided with a read element, and coils located on both sides of the main pole in a manner to sandwich the main pole. The coil located on one side generates the asymmetrical magneto-motive force for magnetizing the main pole to that generated by the coil located on the other side.

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.
