Abstract

New heat assisted magnetic recording (HAMR) head of double grating structure is proposed and simulated using FDTD. Since the near-field optical power strongly depends on the polarization of light, structure of waveguide metal film and enhancement of surface plasmon polariton, it is expected for new head structure to provide greater optical power from the optimization of grating structure for the best resonance tunneling effect and constructive interference.
