Claim 13:
14. A heat-assisted magnetic recording head comprising a near-field transducer comprising:
a near-field emitter configured to heat a surface of a magnetic disk; and
a hybrid plasmonic disk comprising:
a plurality of plasmonic regions; and
a plurality of thermal regions,

wherein the plurality of plasmonic regions and the plurality of thermal regions are provided in an alternating layered configuration,
the layering oriented along an axis which is substantially perpendicular to an air-bearing surface of the heat-assisted magnetic recording head, and
wherein a plasmonic region and a thermal region are coupled to each other at an interface that is substantially parallel to an air-bearing surface of the heat-assisted magnetic recording head, the interface comprising:
a surface of the plasmonic region; and
a surface of the thermal region.
