ABSTRACT:
A magnetoresistive (MR) head using soft adjacent layer (SAL) transverse biasing and having electrical leads with the facing surfaces lying in planes canted with respect to the easy axis of magnetization of the magnetoresistive sensor element for improving the off-track performance of the MR head by making the off-track performance profile more symmetrical, thereby minimizing the difference between the location of its physical center and its magnetic center.
