    摘要： A manufacturing method of a light source chip for a thermally assisted head comprises steps of (a) providing a light source bar with a surface coating formed thereon; (b) forming several blind holes on the predetermined positions of the light source bar by etching, the blind hole having a top hollowed on the surface coating and a bottom hollowed on the light source bar, and the blind hole having a first biggest width at its top; (c) cutting the light source bar along every two adjacent blind holes by a cutting machine The cutting machine has a cutting means with a second biggest width that is smaller than the first biggest width of the blind hole, thereby cutting down an individual light source chip without contacting the side edges of the blind hole. Thus a light source chip with a smooth edge and without cracks on the surface can be obtained; and the surface coating formed thereon is hard to be peeled off.

    摘要： A thin-film magnetic head is constructed such that a main magnetic pole layer, a lower shield layer, an upper shield layer and a thin-film coil are laminated on a substrate. A method of manufacturing the thin-film magnetic head has a lower shield layer forming step. This step comprises a step of forming a first lower shield part in a lower shield planned area, including a planned line along the medium-opposing surface, a step of forming a partial lower seed layer having a partial arrangement structure in which the partial lower seed layer is arranged on a lower formation zone except a lower exception zone including the planned line, a step of forming a second lower shield part on the partial lower seed layer.

    摘要： A method for providing a perpendicular magnetic recording transducer is described. The method and system include providing a metallic underlayer and providing an insulator, at least a portion of which is on the metallic underlayer. The method and system also include forming a trench in the insulator. The bottom of the trench is narrower than the top of the trench and includes a portion of the metallic underlayer. The method and system also include providing a nonmagnetic seed layer that substantially covers at least the bottom and sides of the trench. The method and system also include plating a perpendicular magnetic pole material on at least a portion of the seed layer and removing a portion of the perpendicular magnetic pole material. A remaining portion of the perpendicular magnetic pole material forms a perpendicular magnetic recording pole.

    摘要： A manufacturing method for a heat-assisted magnetic recording head includes the step of forming an internal mirror that includes a reflecting film support body and a reflecting film. The reflecting film support body includes first and second inclined surfaces. The reflecting film includes first and second portions that are located on the first and second inclined surfaces, respectively. The step of forming the internal mirror includes the step of forming the reflecting film support body and the step of forming the reflecting film. The step of forming the reflecting film support body forms an initial support body, and performs two taper-etching processes on the initial support body so that the initial support body is provided with the first and second inclined surfaces.
