Abstract
A heat-assisted magnetic recording head includes a near-field transducer (NFT). The NFT includes a plasmonic disk and a near-field oscillator pair. The near-field oscillator pair includes a receiving oscillator and an emitting oscillator. The receiving oscillator is operatively coupled to the plasmonic disk and configured to receive localized surface plasmons from the plasmonic disk and amplify a near field of the localized surface plasmons. The emitting oscillator is configured to receive the near field from the receiving oscillator and emit the near field toward a surface of a magnetic disk.
