Abstract:
1. A method for manufacturing a thermally-assisted magnetic recording head in which a light source unit and a slider are joined to each other, the light source unit including a light source that is provided in a source-installation surface adjacent to a bonding surface of a unit substrate and has a light emitting surface including a light-emission center adjacent to the bonding surface, the slider including an optical system that is provided on an element-integration surface adjacent to an opposed-to-medium surface of a slider substrate and has a light-receiving end surface reaching a back surface opposite to the opposed-to-medium surface of the slider substrate, the manufacturing method comprising the steps of: causing a light emitted from an alignment light source to enter the light source from a surface opposite to the light emitting surface including the light-emission center of the light source while the bonding surface of the light source unit is opposed to the back surface of the slider substrate, the alignment light source being provided separately from the light source unit and being different from the light source; detecting the light that has passed through the light source and is emitted from the light-emission center to align the light-emission center of the light source unit with the light-receiving end surface of the slider; and bonding the light source unit to the slider in such a way that the bonding surface of the unit substrate and the back surface face each other.
