Abstract
A slider for heat assisted magnetic recording (HAMR) is provided. The slider includes a writer for writing data to a HAMR medium, a reader for reading data stored on the HAMR medium, a near field transducer (NFT), a first waveguide optically coupled to the NFT, a slider laser configured to generate and transmit a first light energy to the first waveguide such that the NFT causes a portion of the HAMR medium to heat up, to assist the writer for writing data to the HAMR medium, and a second waveguide optically coupled to the NFT, for transmitting a light energy from an external laser to the NFT to optically anneal the NFT during a fabrication process of the slider.
