Abstract:
A plasmon generator generates surface plasmon and generates near-field light from the surface plasmon at a distal end surface situated on an air bearing surface facing a magnetic recording medium. The plasmon generator has a first portion including the distal end surface, a second portion situated away from the air bearing surface, and a separating layer situated between the first portion and the second portion and separating the first portion from the second portion.
