摘要： A magneto-resistive (MR) head includes protection from electrostatic discharge without introducing additional processing steps. The MR sensor comprises a soft film biased (SFB) magnetic read sensor sandwiched between two high resistivity magnetic materials. The MR sensor is located between two MR shields wherein each MR shield is connected to an MR sensor ground signal lead by a resistor. The resistor is constructed from the high resistivity magnetic material such that the resistor is deposited at the same process step as the MR sensor.

摘要： The present invention divides the recording head into multiple sections, each section accessing a subset of the total number of channels arranged such that one section reads and writes only a subset of the data channels. The sections may be either independently actuated for both coarse (data band) and fine (track-following) positioning, or linked by a common actuator for data band positioning with independent fine position actuators for fine track following.

摘要： A head includes first and second read modules. The first module has an MR element formed on a wafer having a grating directed along a first direction. The magnetization of the first module element is directed along the first direction. The first module element is biased with a first current directed along a direction such that magnetically stable operation of the element results, that is along an opposite second direction. The second module has an element formed on a wafer having a grating directed along the first direction. The second module is flipped respect to the first module such that the grating is directed along the second direction. The magnetization of the second module element is directed along the second direction. The second module element is biased with a second current directed along the direction opposite to the first current, i.e., the second current is directed along the first direction.

The method includes depositing an insulative layer on a substrate, and depositing a magnetoresistive material on the insulative layer, the magnetoresistive material forming a read element. The method also includes depositing a material on the read element, the material forming a support element and having a hardness sufficient to substantially prevent damage to the read element during mechanical processing or during movement of a tape across a surface of the read element.
