Magnetic disk and process and apparatus for producing the same.

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 min ) thereon, and applying surface waves (vibrator 4) to the magnetic recording film (100, 100 min ) in an undried state. By applying the surface waves to the magnetic recording film (100, 100 min ), 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.
