摘要： A magnetic stack includes a self-supporting substrate that carries first and second layer(s). The first layer(s) comprise a magnetic write pole, and the second layer(s) comprise a semiconductor laser. At least one of the second layer(s) is monocrystalline and incompatible with epitaxial growth on the substrate. No support substrate other than the self-supporting substrate attaches to the second layer(s). The magnetic stack may include a near field transducer (NFT) disposed to receive light emitted by the laser. A waveguide may transmit light from the laser to the NFT, or the NFT may couple to the laser without an intervening waveguide. The magnetic stack may be configured for heat assisted magnetic recording (HAMR).

摘要： An apparatus includes a waveguide configured to deliver light to a transducer region. The apparatus also includes a plasmonic transducer that has two metal elements configured as side-by-side plates on a substrate-parallel plane with a gap therebetween. The gap is disposed along the substrate-parallel plane and has an input end disposed proximate the transducer region and an output end. The transducer is configured to provide a surface plasmon-enhanced near-field radiation pattern proximate the output end in response to the light received by the waveguide.
