An apparatus includes a waveguide shaped to direct light to a focal point,
and a near-field transducer positioned adjacent to the focal point,
wherein the near-field transducer includes a dielectric component and a
metallic component positioned adjacent to at least a portion of the
dielectric component. An apparatus includes a waveguide shaped to direct
light to a focal point, and a near-field transducer positioned adjacent
to the focal point, wherein the near-field transducer includes a first
metallic component, a first dielectric layer positioned adjacent to at
least a portion of the first metallic component, and a second metallic
component positioned adjacent to at least a portion of the first
dielectric component.
