    摘要： A thermally assisted magnetic head includes a main magnetic pole layer, a near-field light generating layer having a generating end part generating near-field light arranged within a medium-opposing surface, and an optical waveguide guiding light to the near-field light generating layer. The near-field light generating layer has a laminated structure in which a first thin-film metal layer formed in a thin film form along a direction intersecting the medium-opposing surface and a second thin-film metal layer formed in a thin film form and formed using a second metal larger in hardness than a first metal forming the first thin-film metal layer are alternately laminated. Further, in the second thin-film metal layer, a defect part is formed, the defect part is a part smaller in thickness than another part or is a hole part, and a flat layer part other than the defect part surrounds the defect part.

    摘要： A method for manufacturing a thermally-assisted magnetic recording head is provided, in which a light source unit including a light source and a slider including an optical system are bonded. A unit substrate is made of a material transmitting light having a predetermined wavelength, and a unit adhesion material layer that contains Sn, Sn alloy, Pb alloy or Bi alloy is formed on the light source unit and/or the slider. The manufacturing method includes: aligning the light source unit and the slider in such a way that a light from the light source can enter the optical system and the unit adhesion material layer is sandwiched therebetween; and causing a light including the predetermined wavelength to enter the unit substrate to melt the unit adhesion material layer. The unit adhesion material layer melted by the light including the predetermined wavelength can ensure high alignment accuracy as well as higher bonding strength and less change with time.
