Abstract
A magnetoresistive read head having a corrugated magnetoresistive layer wherein the corrugated section does not encroach on magnetic elements on either end of the magnetoresistive layer. The corrugations in the magnetoresistive layer stabilize the magnetization in the center region of the read head, while the magnetic elements stabilize the magnetization at the ends. By separating the two stabilization methods, unfavorable interactions between them is reduced.
