Patent ID: 8824086

Claim:
An apparatus comprising: a waveguide configured to deliver light to a transducer region; a plasmonic transducer that includes at least one metal plate element having an input end disposed proximate the transducer region; a recording pole proximate the plasmonic transducer at the air-bearing surface; a heat sink between the plasmonic transducer and the recording pole, surrounding at least three sides of the recording pole, and extending along at least one side of the recording pole that does not face the plasmonic transducer; and an air-bearing surface disposed at an angle to the substrate-parallel plane, wherein an output end of the at least one metal plate element is disposed proximate the air-bearing surface, wherein the plasmonic transducer is configured to provide a surface plasmon-enhanced near-field radiation pattern proximate the output end in response to the light received at the transducer region.
