Title: Magneto-resistive head having the sensor orthogonally positioned relative to the write gap

Abstract: There is provided a magneto-resistive head in a hard disk drive. In the magneto-resistive head, an upper write pole has a write track width, and a lower write pole is positioned under the upper write pole, separated by a predetermined write gap. A magneto-resistive sensor is positioned under the lower write pole, apart by a predetermined gap and orthogonally to the length of the write gap, and has a predetermined read track width, for efficiently reading data from a disk. A shield is positioned under the magneto-resistive sensor, separated by a predetermined gap.
