Abstract:
Embodiments disclosed herein generally relate to a HAMR head. The HAMR head includes a main pole, a waveguide and a NFT disposed between the main pole and the waveguide. The NFT includes an antenna, and the antenna includes a first portion and a second portion. The second portion may be made of a material having a higher melting point than the material of the first portion. Having the second portion helps reduce the temperature rise of the NFT and reduce the laser power applied to the NFT.
