Method of manufacturing thermally-assisted magnetic recording head

A method of manufacturing a thermally-assisted magnetic recording head, the method comprising:

• providing a bar and a plurality of light source units, the bar including a plurality of thermally-assisted magnetic recording head sections arranged in a first direction that is a longitudinal direction, and each of the light source units including a substrate and a light source mounted on the substrate;
• bonding a second surface of the substrate to the bar with an adhesive layer in between, where the plurality of light source units are so aligned to the respective thermally-assisted magnetic recording head sections on the bar, as to allow a first surface of the substrate, which supports the light source, to be parallel to the first direction, the bonding allowing the substrates of the light source units to be irradiated with a first laser beam and allowing the bar to be irradiated with a second laser beam, to thereby allow the adhesive layer to be melted;
• and
• separating the bar into a plurality of sliders each including one of the thermally-assisted magnetic recording head sections.
