摘要： Concave grooves for forming a receiving layer for inkjet printing are provided at the inner peripheral and outer peripheral boundary portions of an application region on a disk substrate. The concave grooves are formed with a substantially V-shaped cross section, and with a depth d that is at least equal to the film thickness of the coating film within a central region between the concave grooves. A plurality of nozzles of a supply device is arrayed in a radial direction across the central region between the concave grooves, and a substantially constant quantity of coating liquid per unit of surface area is applied so as to form a coating film of a predetermined thickness. The applied coating liquid portions are flattened by a mutual leveling effect. During drying, the coating film inside the concave grooves does not dry first, but rather dries and contracts at substantially the same time as the coating film within the central region, meaning a receiving layer of uniform film thickness can be formed over the entire central region.
