Abstract
A heat-assisted magnetic recording head includes a near-field transducer, a waveguide, and a resonance enhancing feature. The near-field transducer is configured to focus and emit an optical near-field. The waveguide is configured to receive electromagnetic radiation and propagate the electromagnetic radiation toward and proximal to the near-field transducer. The resonance enhancing feature is disposed proximal to the near-field transducer and to a media-facing surface of the heat-assisted magnetic recording head. The resonance enhancing feature includes a first segment and a second segment disposed on opposite sides of the near-field transducer relative to a cross-track dimension of the heat-assisted magnetic recording head. Each of the first segment and the second segment of the resonance enhancing feature includes a liner and a filler. The liner of each of the first segment and the second segment at least partially faces the near-field transducer. The filler of each of the first segment and the second segment is disposed distal to the near-field transducer relative to the liner of the respective segment.
