Abstract
A method for manufacturing an optical disk having a middle layer on a substrate includes the steps of coating an ultraviolet curing resin over the substrate, irradiating ultraviolet rays to the ultraviolet curing resin and prepolymerizing the ultraviolet curing resin, and forming the middle layer by pressing a stamper against the prepolymerized ultraviolet curing resin, irradiating ultraviolet rays to the ultraviolet curing resin and thus curing the ultraviolet curing resin.
