    摘要： A method of manufacturing a plasmon generator includes the steps of: an initial film made of a metal polycrystal and including a pre-plasmon-generator portion that later becomes the plasmon generator; heating the initial film with heating light so that a plurality of crystal grains constituting the metal polycrystal grow at least in the pre-plasmon-generator portion; stopping the heating of the initial film; and forming the plasmon generator by processing the initial film after the step of stopping the heating. The step of forming the plasmon generator includes the step of providing the pre-plasmon-generator portion with a front end face that generates near-field light.

    摘要： A plasmon generator configured to excite a surface plasmon based on light includes a first portion formed of a first metal material and a second portion formed of a second metal material different from the first metal material. The plasmon generator has a front end face. The front end face includes a near-field light generating part that generates near-field light based on the surface plasmon. The second portion includes an end face located in the front end face. The second metal material satisfies at least one of the following requirements: a lower ionization tendency than that of the first metal material; a lower electrical conductivity than that of the first metal material; and a higher Vickers hardness than that of the first metal material.

    摘要： In a method of forming a main pole, an initial accommodation layer is etched by RIE using a first etching mask having a first opening, whereby a groove is formed in the initial accommodation layer. Next, a part of the initial accommodation layer including the groove is etched by RIE using a second etching mask having a second opening, so that the groove becomes an accommodation part. The main pole is then formed in the accommodation part. The first etching mask has first and second sidewalls that face the first opening and are opposed to each other at a first distance in a track width direction. The second etching mask has third and fourth sidewalls that face the second opening and are opposed to each other at a second distance greater than the first distance.
