Abstract

A magnetoresistive head comprising, a magnetic yoke defining a magnetic gap for guiding signal magnetic fields from a recording medium at the air-bearing surface, a giant magnetoresistive element magnetically coupled with the magnetic yoke at a position remote from the air-bearing surface, and means for supplying a sense current in a direction substantially perpendicular to the surface of the giant magnetoresistive element.
