Abstract
The present disclosure generally relates to an EAMR head having a plasmonic bulk metal plate adjacent thereto. The waveguide core has a trapezoidal shaped cross-section, when viewed from the ABS, and the plasmonic bulk metal plate is disposed adjacent the short side of the trapezoid. The plasmonic bulk metal plate reduces the temperature of the NFT.
