Abstract
A plasmon generator generates a surface plasmon, and generates a near-field light from the surface plasmon on a front end surface positioned on an air bearing surface opposing to a magnetic recording medium. The plasmon generator has a first surface that is adjacent to the front end surface and that faces a lower layer where the plasmon generator is deposited, and a second surface at the back side of the first surface relative to a down track direction. The first surface tilts toward a surface that is orthogonal to the down track direction, and, is parallel to across track direction, and the plasmon generator is deposited with a (111) orientation from the first surface toward the second surface.
