Abstract
A non-magnetic magnetoresistive head for reading a magnetic pattern stored as domains in tracks on a storage device uses as the sensor a wafer of a high electron mobility non-magnetic semiconductor, such as indium antimonide or mercury-cadmium telluride, which includes an electrode configuration that includes an inner stripe electrode and an outer rectangular electrode surrounding the inner electrode. The wafer is supported so that the plane of the wafer is parallel to the disk and perpendicular to the magnetic field being sensed.
