发明名称 Method and system for providing an energy assisted magnetic recording disk drive having a non-conformal heat spreader
摘要 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, a heat spreader, and at least one coil. The waveguide directs the energy from the laser toward the ABS. The NFT is optically coupled with the waveguide, focuses the energy onto the media, and includes a disk having an NFT width. The write pole writes to the media. The heat spreader is thermally coupled with the NFT. A first portion of the heat spreader is between the NFT and the pole, is between the ABS and a second portion of the heat spreader, and has a first width. The second portion has a second width greater than the first width.
