Claim 16:
17. A method of fabricating the near field transducer in the TAMR head of claim 9, comprising:
providing a near field transducer in a TAMR head;
determining the effective current Ieff at 100% for optimal ADC performance of the TAMR head on a spin stand with a TAMR disk, PMR disk, or glass disk; and
self-annealing the peg portion or the peg by applying an overdriven Ieff in the range of 120% to 210% for 0.1 to 60 seconds to the peg at passive flight to form a single peg grain with a desired (111) orientation.
