Claim 0:
1. 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;
a waveguide; and
a hybrid plasmonic disk comprising:
a plasmonic region comprising a plasmonic material; and
a thermal region comprising a material that is different than the plasmonic material,

wherein the hybrid plasmonic disk is coupled to the waveguide or to the near-field emitter at an interface that is substantially orthogonal 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 of the hybrid plasmonic disk.
