Abstract:
1. A method for manufacturing a thermally-assisted magnetic recording head in which a light source unit including a light source provided in a unit substrate and a slider including an optical system provided in a slider substrate are joined with each other, wherein the unit substrate is made of a material transmitting light having a predetermined wavelength and a unit adhesion material layer is formed on a surface of one or each of the light source unit and the slider, the unit adhesion material layer containing a material selected from a group consisting of tin, tin alloy, lead alloy and bismuth alloy, the manufacturing method comprising the steps of: aligning the light source unit and the slider with each other in such a way that a light generated from the light source can enter the optical system and the unit adhesion material layer is sandwiched between the light source unit and the slider; causing a light including the predetermined wavelength to enter the unit substrate to melt the unit adhesion material layer; and bonding the light source unit and the slider with each other.
