Spin coating process and manufacturing method of disc-shaped recording medium

摘要

Disclosed is a spin coating process capable of removing a swelling in the vicinity of an outer peripheral edge by a simple process when forming an ultraviolet curing resin layer (13a). Disclosed also is a method of manufacturing a disc-shaped recording medium, capable of eliminating an influence of the swelling, etc. in the vicinity of an outer peripheral edge of a resin layer such as a light transmissive layer, etc.. The spin coating process involves spin-coating an energy beam curing resin (13) over a resin-formed surface of a disc-shaped member (11), irradiating the resin-formed surface spin-coated with the energy beam curing resin with an energy beam (5a) except the vicinity of an outer peripheral edge thereof, and removing an uncured portion of the energy beam curing resin by applying a solvent to the vicinity of the outer peripheral edge of the resin-formed surface.
