Abstract
An energy assisted magnetic recording (EAMR) head having a stress buffer for reducing the stress on a near-field transducer during thermal expansion and methods for fabricating the EAMR head are provided. The EAMR head includes a waveguide, a near-field transducer (NFT) configured to receive optical energy from the waveguide, and a cladding of the waveguide has an opening. The NFT is positioned within the opening, and an air gap is formed between the NFT and a side wall of the opening.
