Abstract

A plasmon generator includes a first portion and a second portion that are adjacent in a first direction orthogonal to the direction of travel of light propagating through a core. The second portion includes a front end face located in a medium facing surface of a magnetic head. The core has a concave portion recessed from the top surface of the core. At least part of the first portion is received in the concave portion. The concave portion has a surface including an evanescent light generating portion. The first portion includes a plasmon exciting portion opposed to the evanescent light generating portion. The evanescent light generating portion is inclined relative to a first surface.
