ABSTRACT:
A magnetoresistive magnetic head comprises a first magnetic shielding layer formed on an underlying layer, a first nonmagnetic insulating layer formed on the first magnetic shielding layer, a magnetoresistive device formed on the first nonmagnetic insulating layer, first and second leads formed on the first nonmagnetic insulating layer to be connected to both sides of the magnetoresistive device respectively, a second nonmagnetic insulating layer formed to cover the first and second leads and the magnetoresistive device, a second magnetic shielding layer formed on the second nonmagnetic insulating layer to be positioned over the magnetoresistive device, and a resistor element buried in at least one of the first and second nonmagnetic insulating layers to electrically connect the first lead to either the first magnetic shielding layer or the second magnetic shielding layer.
