Systems and methods for coating a near field transducer in a dielectric material are described. In one embodiment, the method may include forming a liquid solution comprising at least a first dielectric and a disk surface lubricant, forming a coating of the liquid solution on an outer surface of a storage medium based at least in part on dipping the storage medium in the liquid solution, and accumulating a first set of molecules of the first dielectric on a near field transducer (NFT) of a HAMR head based at least in part on evaporating a first portion of the first dielectric in the coating by performing a first HAMR writing operation that shines a laser on the coating.
