Thermal assisted magnetic recording head with plasmon generator

A thermal assisted magnetic recording head that performs magnetic recording while locally heating a magnetic recording medium, comprising:

• a plasmon generator that generates a surface plasmon, and that generates near-field light from the surface plasmon on a front end surface positioned on an air bearing surface opposite to the magnetic recording medium,
• a dielectric body layer positioned around the plasmon generator, and
• an adhesion layer positioned between the plasmon generator and the dielectric body layer, wherein:
• the adhesion layer is made from at least one of IrOx, RuOx, NiOx and CoOx, and
• the dielectric body layer is made from AlOx or SiOx and
• the plasmon generator and the adhesion layer are thermally treated at a temperature of 200° C. or higher.
