Patent ID: 8385021

Claim:
A magnetic recording element comprising: a substrate; a main pole for recording that includes an edge part positioned on an air bearing surface (ABS); a waveguide through which a laser light propagates; a plasmon generator that is positioned away from the substrate, that extends to the ABS as facing a part of the waveguide, and that has a propagation edge extending in a longitudinal direction, the propagation edge has an overlapping part and a near field light generator, the overlapping part overlapping the waveguide in the longitudinal direction, the near field light generator positioned on the ABS and located in the vicinity of the edge part of the main pole, the overlapping part of the propagation edge coupled with the laser light propagating through the waveguide in a surface plasmon mode so that a surface plasmon is generated, the propagation edge propagating the surface plasmon generated in the overlapping part to the near field light generator; and a grounding element that electrically connects the plasmon generator and the substrate without grounding through the main pole.
