ABSTRACT:
A method of establishing a single domain in a magnetoresistive sensor positioned in a gap between two shield layers of magnetic material. The method includes the steps of heating the magnetoresistive head above the Neel temperature of at least one of the shield layers of magnetic material. Applying an external magnetic field to the magnetoresistive sensor and the shield layers for establishing a single magnetic domain in the magnetoresistive sensor. Reducing the intensity of the external magnetic field for holding the magnetization of the magnetoresistive sensor during cooling. Cooling the magnetoresistive head.
