Heat-assisted magnetic recording head with a resonance enhancing feature

A heat-assisted magnetic recording head comprising:

• a near-field transducer configured to focus and emit an optical near-field;
• a waveguide configured to receive electromagnetic radiation and propagate the electromagnetic radiation toward and proximal to the near-field transducer;
• and
• a resonance enhancing feature disposed proximal to the near-field transducer and to a media-facing surface of the heat-assisted magnetic recording head,
• the resonance enhancing feature comprising 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,
• wherein each of the first segment and the second segment of the resonance enhancing feature comprises:
• a liner that at least partially faces the near-field transducer;
• and
• a filler disposed distal to the near-field transducer relative to the liner,
• wherein the liner of each of the first segment and the second segment comprises an edge,
• wherein a part of the edge of each liner of the first segment and the second segment faces the near-field transducer, and
• wherein the edge of each liner of the first segment and the second segment is separated from the near-field transducer by a gap.
