    摘要： A method of forming projections on major surfaces of a disk comprises the steps of supporting the disk in a space, spraying a multiplicity of fine solid particles into the space, charging the sprayed fine solid particles with electricity of the same polarity so that the fine solid particles are floating in the space in a mutually separated state due to electric repellent forces acting between the fine solid particles, electrostatically depositing the fine solid particles charged with electricity on the surfaces of the disk, and etching the disk surfaces by using the deposited fine solid particles as masks, thereby forming a multiplicity of projections on the disk surfaces.

    摘要： This invention relates to the magnetic recording medium, its manufacturing method and the magnetic disk apparatus, in which the ferromagnetic thin film is formed on the substrate board, and the protective layer is provided on that. A Magnetic recording medium of the has at least one layer of the protective layer on the magnetic surface, which is characterized in that the surface of the protective layer is provided with the high noncontinuous large resistance layer, and the density of the surface of the protective layer is higher than other regions other than the said surface. The magnetic recording medium has the surface of the protective layer which contains at least one kind or more of the element of the inert gas element, the halogen element and hydrogen. Therefore, when making a lower flying height of the magnetic head is achieved, the slide durability over the long term is improved, particularly, the slide durability of the magnetic disk apparatus using the MR head can be improved.

    摘要： Above a substrate mounted on rollers, an upper board is prepared a predetermined distance apart from the substrate. A pipe fills a space between the upper board and the substrate with washing water by supplying the washing water at a predetermined flow rate. A washing water layer is formed evenly on an upper surface of the substrate when the substrate passes below the upper board. Below the substrate, a lower board is prepared a predetermined distance apart from the substrate. A pipe fills a space between the lower board and the substrate with the washing water by supplying the washing water at a predetermined flow rate. A washing water layer is formed evenly on a lower surface of the substrate when the substrate passes above the lower board. The air emitted from an air knife is sprayed to the upper/lower surface of the substrate slantingly at a predetermined incident angle in an opposite direction of a substrate moving direction. The washing water is pushed away and removed from the upper/lower surface of the substrate.
