Abstract

PURPOSE: To make coating film of both surfaces of a magnetic disk, etc. uniform and reduce the rate of occurrence of defective products by rotating a disk to be coated horizontally and applying magnetic coating on both sides of the disk, and placing a cover plate and a bottom plate at proper positions above and below the disk.
CONSTITUTION: A disk 2 for magnetic disk etc. is fixed on a supporting stand 1 by screwing with a cover 3. A cover plate 5 is provided above a part where the coating film of this disk 2 is formed, and a bottom plate 7 is placed below. The distance between the cover plate 5 and the disk 2 in made shorter than the distance between the bottom plate 7 and the disk 2. The disk 2 is rotated horizontally in this device and coating is sprayed on both sides of the disk 2 from feed tubes 4a, 4b. The feed tubes 4a, 4b are moved back and forth in the direction of diameter to let sprayed coating adhere the whole surface of the disk 2. By this method and device, difference of thickness of coating film can be eliminated.
