Zusammenfassung:A method, according to one embodiment, includes forming a lubricant film on a magnetic disk having at least a magnetic recording film above a substrate, and a protective film above the magnetic recording film, and wiping the lubricant film while rotating the substrate, e.g., at about 3.0 m/s to about 3.5 m/s by pressing a pad against a wiping cloth e.g., at a loading speed of about 12 mm/min to about 36 mm/min e.g., under a pressure of about 3 gf/mm2 to about 9 gf/mm2. The pad has a convexly curved surface in contact with the wiping cloth, and the wiping cloth is disposed so as to oppose the lubricant film. The method also includes pressing a cleaning tape which includes abrasive grains against the substrate on which the protective film and lubricant film are formed while rotating the substrate to remove protrusions. Apparatuses and forming the layers are also described.
