ABSTRACT:
Provided is a method for manufacturing a heat-assisted magnetic recording head, capable of joining a light source unit and a slider with a sufficiently high alignment accuracy. In the method, the unit including a light source is joined to the slider including a head part. First, at least one marker provided on the head-part end surface is set so that the distance from the waveguide incident center to the marker end is substantially equal to the distance from the light-emission center of the light source to the end surface of the light source. After that, the unit and slider are relatively moved while keeping the unit in surface contact with the slider, and the relative positions are set so that the end of the marker coincides with, or is at a distance within an acceptable range from, the edge of the surface of the light source.
