Heat assisted magnetic recording apparatus having a plurality of near-field transducers in a recording media
摘要:
An apparatus includes a recording media including a substrate, a plurality of islands of magnetic material on the substrate, and a non-magnetic material between the islands, a recording head having an air bearing surface positioned adjacent to the recording media, and including a magnetic pole, and an optical transducer, wherein the optical transducer directs electromagnetic radiation onto recording media to heat portions of the recording media and a magnetic field from the magnetic pole is used to set the direction of the magnetization in the heated portions of the recording media, and a plurality of near-field transducers, each positioned adjacent to one of the islands to increase coupling between the electromagnetic radiation and the magnetic material.
