A heat-assisted magnetic recording head includes a waveguide and a near-field transducer. The near-field transducer includes a plasmonic disk disposed proximal to the waveguide. The plasmonic disk includes a first plasmonic layer, a second plasmonic layer, and a middle layer. The first plasmonic layer is coupled to the waveguide. The second plasmonic layer is disposed distal to the waveguide relative to the first plasmonic layer. The middle layer is disposed between the first plasmonic layer and the second plasmonic layer.
