Abstract
PURPOSE: To form a fine magnetic film and increase the performance of a magnetic recording medium, by vibrating the vertical magnetic field generating magnetic pole via an oscillator when the vertical magnetic field is applied to a magnetic film.
CONSTITUTION: The magnetic film 2 is formed on the substrate 1, and the vertical magnetic field is applied to the film 2 through the vertical magnetic field generating magnetic pole 3. In this case, the pole 3 is vibrated by means of the oscillator 4. At the same time, an orientation magnetic field is formed by the orientation magnetic pole 5. In such way, the coarseness on the surface of a magnetic recording medium of a magnetic disk or the like is improved in a simple process. At the same time, the fluidness of the coating liquid is improved to increase the uniformity of coating. As a result, the performance of a magnetic disk or the like is enhanced.
