Abstract
A method of manufacturing an optical disc includes easily removing a bump formed on a circumference of the optical disc during forming a transparent layer by using a spin-coating method to form the optical disk having a high-density recording capacity. The method includes preparing a substrate having a diameter larger than that of a desired disc, applying an ultraviolet hardening resin to the substrate and forming a transparent layer having a predetermined thickness by a spin-coating method, illuminating an ultraviolet ray on the transparent layer and a bump formed on a circumference of the transparent layer to be hardened, and cutting out the bump by using a puncher. According to the method, the bump which inevitably occurs when the transparent layer is formed, can be easily cut out by a puncher.
