Abstract

PURPOSE:To thinly form a perpendicularly oriented magnetic Ba film by discharging a magnetic coating compd. from the inside circumferential part to the outside circumferential part of a disk substrate to coat said compd. on the substrate while changing the rotating speed of the substrate continuously in such a manner that the specified linear circumferential speed is maintained in the position of a nozzle port for discharging the magnetic coating compd., thereby forming the magnetic film. CONSTITUTION:The magnetic coating compd. is dropped always at the specified linear circumferential speed by shifting the dropping position of the magnetic coating compd. gradually from the inside circumferential part to the outside circumferential part and changing the linear circumferential speed gradually according to the dropping position. Namely, the rotating speed of the substrate is gradually lowered as the dropping positions shifts from the inside circumferential part to the outside circumferential part. The formation of the coated film is, therefore, executed while the outside edge part of the coated film which is previously half cured by the solvent of the coating compd. dropped afterward. The film thickness is thereby reduced.
