ABSTRACT:
Methods of fabricating an energy-assisted magnetic recording (EAMR) head to compensate for a heat-induced protrusion of a near field transducer formed therein are disclosed. The methods can include applying optical power to the near field transducer to generate heat therein. The near field transducer protrudes beyond an air bearing surface of the EAMR head by the generated heat. The methods can further include removing a protruded portion of the near field transducer.
