Abstract
An energy assisted magnetic recording (EAMR) transducer coupled with a laser is described. The EAMR transducer has an air-bearing surface (ABS) residing near a media during use. The laser provides energy. The transducer includes a waveguide, a near field transducer (NFT) proximate to the ABS, a write pole and at least one coil. The waveguide directs the energy from the laser toward the ABS. The NFT is optically coupled with the waveguide and focuses the energy onto a region of the media. The write pole writes to the region of the media. The write pole has a magnetic portion and a nonmagnetic liner. The magnetic portion has a plurality of sides and a pole thermal conductivity. The nonmagnetic liner is adjacent to at least the sides of the magnetic portion, and has a liner thermal conductivity greater than the pole thermal conductivity. The coil(s) are for energizing the write pole.
