摘要： A coating type, magnetic disk is produced by applying a magnetic paint containing magnetic powders in a dispersed state to a non-magnetic substrate, thereby forming a magnetic recording film thereon, and applying surface waves to the magnetic recording film in an undried state. By applying the surface waves to the magnetic recording film, dispersibility and orientation of the magnetic powders are improved and a longitudinally oriented, coating type magnetic disk with distinguished electromagnetic properties, such as a high S/N ratio, etc. can be obtained.

摘要： The magnetic recording medium includes at least a substrate, a magnetic film formed on the substrate for storing data, a protective film and a lubricant film. The protective film has two regions of a predetermined pattern each having a different surface energy. The lubricant film including polar groups is formed on the protective film including the regions. The degree of adhesion of the lubricant film to the protective film is thus changed at the two regions each having a different surface energy so that the lubricant film can be prevented from being scattered.

摘要： A thin film magnetic disc in which dot-like scattered bumps, made of a material different from that of the protective layer, are formed on the protective layer, and a lubricant layer is formed on the surfaces of the protective layer and the scattered bumps. A protective layer excellent in strength and disk durability is obtained by using a material different from that of the bumps. The functions of the protective layer and scattered bumps are separated from each other and make full use of the different materials. Such a protective layer is effective to reduce spacing between a head and the disc.
