    摘要: Provided is a method for manufacturing a thermally-assisted magnetic recording head including a light source unit with a light source and a slider with an optical system. The method comprises steps of: adhering by suction the light source unit with a back holding jig; moving the back holding jig, then aligning a light-emission center of the light source with a light-receiving end surface of the optical system in directions within a slider back surface of the slider; bringing the light source unit into contact with the slider back surface, with a suction surface of the back holding jig tilted from the normal to the slider back surface; applying a load to a load application surface of the unit substrate by a loading means to bring a joining surface of the light source unit into conformity with the slider back surface; and bonding the light source unit and the slider. This method can improve the conformity, thereby achieving adequately strong junction and adequately high accuracy in position.

    摘要: The thermally-assisted magnetic recording head includes: a magnetic pole; a waveguide propagating light in a first direction, the first direction intersecting with an air bearing surface; a plasmon generator having a base and a projection, the base having a surface, and the projection having a top, standing partially on the surface of the base and extending in the first direction. The plasmon generator has a first portion and a second portion, and the first portion and the second portion are provided in this order from the air bearing surface in a direction away from the air bearing surface. Herein, the top of the projection and the surface of the base in the first portion define a first step, and the top of the projection and the surface of the base in the second portion define a second step. The first step is larger than the second step.
