Magnetoresistive read head having permanent magnet on top of magnetoresistive element

摘要

A magnetoresistive read head. The magnetoresistive read head includes a magnetoresistive element including a lower surface and an upper surface, wherein an electrical resistance of the magnetoresistive element varies in response to varying magnetic fields adjacent to the lower surface of the magnetoresistive element, and a magnetic element adjacent to the upper surface of the magnetoresistive element.
