Abstract
The present disclosure generally relates to a magnetic recording head for a magnetic media drive. The magnetic recording head comprises a main pole, a waveguide disposed adjacent to the main pole, a near field transducer (NFT) coupled between the main pole and the waveguide at a media facing surface (MFS), a thermal shunt disposed on the NFT, the thermal shunt being recessed from the MFS, and a stable material disposed on the NFT at the MFS. In some embodiments, the stable material is wedge-shaped or triangular-shaped. In another embodiment, the stable material comprises a first portion and a second portion, where the first and second portions may each by linear, or where the first portion is triangular-shaped and the second portion is square-shaped. The stable material may be in contact with the thermal shunt, or spaced from the thermal shunt.
