Claim 15:
16. The heat-assisted magnetic recording head of claim 14,
wherein the axis defines a layering dimension,
wherein a first thermal region comprises:
a first end proximate to the air-bearing surface of the heat-assisted magnetic recording head and a peg portion of the near-field emitter, the first end a first distance from the air-bearing surface in the layering dimension; and
a second end opposite the first end, the second end a second, greater distance from the air-bearing surface in the layering dimension,

wherein a first plasmonic region comprises:
a first end that is coupled to the second end of the first thermal region, and
a second end that is a third distance from the air-bearing surface in the layering dimension, the third distance greater than the second distance, and

wherein a second thermal region comprises:
a first end that is coupled to the second end of the first plasmonic region, and
a second end that is a fourth distance from the air-bearing surface in the layering dimension, the fourth distance greater than the third distance.
