Abstract: 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.

Abstract: 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.

Abstract: A multitrack coupled element read head and a method for manufacturing such a read head are provided. The multitrack coupled element read head includes multiple coupled magnetoresistive read elements in a spaced relationship, and a support structure between a pair of coupled read elements, the support structure also being a magnetoresistive material. The read head also includes a closure material bonded on the plurality of coupled read elements and the support structure, where the support structure provides for substantially even pressure on the pair of coupled read elements such that shorting therein is eliminated.

Abstract: A reproducing element for use in a high density coupled element read head, and a method for manufacturing such an element are provided. The reproducing element includes an insulative layer and a magnetoresistive element in contact with the insulative layer. The reproducing element also includes a support element in contact with the magnetoresistive layer, the support element having a hardness sufficient to substantially prevent damage to the magnetoresistive element during mechanical processing and during movement of a tape across a surface of the magnetoresistive element. 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.

Abstract: 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.
