摘要： A heat assisted magnetic recording (HAMR) assembly includes a slider, a laser diode and solder connections between the laser diode and the slider. The solder connections mechanically and electrically attach the laser diode to the slider. Each solder connection has a total volume per unit area (i.e., height) of less than or equal to about 15 μm. The solder connections have a first intermetallic zone adjacent to the laser diode, a second intermetallic zone adjacent to the slider, and a eutectic zone of eutectic material between the first and second intermetallic zones. The eutectic zone occupies greater than or equal to about 35% of the total volume per unit area of the solder connection.

摘要： Provided is a method for manufacturing a thermally-assisted magnetic recording head in which a light source unit including a light source and a slider including an optical system are joined. The method comprises steps of: adhering by suction the light source unit with a back holding jig; bringing the light source unit into contact with a slider back surface of the slider; applying a load to a load application surface of the light source unit by a loading means to bring a joining surface of the light source unit into conformity with the slider back surface; positioning the light source unit apart from the slider, and then aligning the light source with the optical system; bringing again the light source unit into contact with the slider; and applying a load again to the load application surface to bring the joining surface into conformity with the slider back surface. Thus, the conformity between them can be significantly increased, thereby achieving adequately strong junction and adequately high accuracy in position.
