Abstract
The present embodiments relate to a heat-assisted magnetic recording (HAMR) write head with a NFT bi-layer structure with a bottom taper, which can be applied to one or both layers of the two layers. A heat-assisted magnetic recording (HAMR) write head can include a main pole including a tip portion configured to interact with a magnetic recording medium at an air-bearing surface (ABS). The HAMR write head can further include a near-field transducer (NFT) that includes a dielectric waveguide, a plasmon generator (PG) layer, and a second layer. The second layer can include a thermo-mechanically stable material disposed adjacent to the PG layer. Further, the PG layer and the second layer can form a taper angle relative to the ABS ranging between 30 and 60 degrees.
