Abstract:
A magnetic recording head includes: a main magnetic pole containing a ferromagnetic layer; a main magnetic pole-magnetization fixing portion containing an antiferromagnetic layer in contact with at least one side surface of the main magnetic pole; a heater for heating at least the main magnetic pole so that a magnetic interaction between the main magnetic pole and the main magnetic pole-magnetization fixing portion can be decreased; and a magnetic field generator for generating a magnetic field so as to direct a magnetization of the main magnetic pole in one direction.
