Recent recording areal density and integrated drive performance demonstrations using Heat Assisted Magnetic
Recording (HAMR) suggest that it is a viable technology to succeed conventional magnetic recording. However
challenges still remain for the near field transducer, in particular reliability and sufficient thermal confinement. We
explore a new NFT design, Near field Transducer Gap (NTG), which offers the potential to mitigate some of the issues
in track confinement and thermal profile compared to earlier published studies [4]. The design offers efficiency
improvements, and the potential to reduce unwanted background light and heating that can lead to erasure in the writing
track, and neighbors.
