Abstract:
1. A magnetoresistive head comprising: a first magnetic shield; a first electrode terminal arranged on said first magnetic shield at an entry side of a magnetic field from a carrier; a third electrode terminal that is spaced from said first electrode terminal, and arranged on said first magnetic shield at a side opposite to the entry side of the magnetic field from the carrier; a magnetoresistive coating arranged on said first and third electrode terminals; a second electrode terminal that is arranged on the magnetoresistive coating, and opposed to said first electrode terminal; a second magnetic shield arranged on said second electrode terminal; a sense current source connected to said first and second electrode terminals, said sense current source applying sense current in a direction perpendicular to a coating surface of said magnetoresistive coating; and a bias current source that is connected to and applies bias current to said third electrode terminal and one of said first and second electrode terminals.
