    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 (3), thereby forming a magnetic recording film (100, 100′) thereon, and applying surface waves (vibrator 4) to the magnetic recording film (100, 100′) in an undried state. By applying the surface waves to the magnetic recording film (100, 100′), 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.
