摘要： A method of manufacturing a thermally-assisted magnetic write head is provided. The method includes steps of: forming a laminate structure including the waveguide; the plasmon generator, and the magnetic pole in order; performing a first polishing process to planarize an end surface of the laminate structure; performing a first etching process to remove impurity attached on the end surface of the laminate structure, and to allow the plasmon generator to be recessed from the waveguide and the magnetic pole, thereby forming a recessed region on the end surface of the laminate structure; forming a protection layer on the end surface of the laminate structure such that at least the recessed region is filled; and performing a second polishing process on the end surface of the laminate structure formed with the protection layer until the plasmon generator is exposed, thereby completing the air bearing surface.

摘要： A method of manufacturing a thermally-assisted magnetic recording head includes the steps of: forming a preliminary head section that has a surface to be polished and includes a magnetic pole, a waveguide, and a preliminary plasmon generator; causing a volumetric expansion of the preliminary plasmon generator with heat by introducing light into the core of the waveguide of the preliminary head section; and polishing the surface to be polished of the preliminary head section into a medium facing surface. The preliminary plasmon generator has an end face located in the surface to be polished. In the step of polishing the surface to be polished, the surface to be polished is subjected to polishing with the preliminary plasmon generator expanded in volume, whereby the end face of the preliminary plasmon generator is polished into the front end face, and the preliminary plasmon generator thereby becomes the plasmon generator.

摘要： Disclosed is a method of polishing a magnetic head slider whereby a by-processed step can be easily reduced. An air bearing surface of the magnetic head slider is polished with setting a bar that includes the magnetic head slider where a thin film magnetic head element is formed to reciprocate in a radius direction of a polishing plate, as well as rotating the polishing plate having a polishing surface. Polishing steps include a first polishing step of performing a height polish while rotating the polishing plate at a first velocity, and a second polishing step of performing a finishing polish while rotating the polishing plate at a second velocity sufficiently lower than the first velocity. The second velocity at the second polishing step is set so that an average linear velocity in the direction of the rotation of the polishing plate is equal to or lower than 0.032 m/s (preferably equal to or lower than 0.008 m/s). Consequently, the by-processed step that is generated on the air bearing surface of the magnetic head slider is reduced.
