ABSTRACT:
A magnetoresistive head includes a first magnetic shield, a first electrode terminal arranged on the first magnetic shield at an entry side of a magnetic field from a carrier, a third electrode terminal that is spaced from the first electrode terminal, and arranged on the first magnetic shield at a side opposite to the entry side of the magnetic field from the carrier, a magnetoresistive coating arranged on the first and third electrode terminals, a second electrode terminal that is arranged on the magnetoresistive coating, and opposed to the first electrode terminal, a second magnetic shield arranged on the second electrode terminal, and a sense current source connected to the first and second electrode terminals, which applies sense current in a direction perpendicular to a coating surface of the magnetoresistive coating.
