Abstract:
A method for producing optical discs is provided. A substrate for an optical disc is formed by utilizing a molding process. A textured surface is formed at an outer diameter edge of the substrate. A protective coating is applied to cover the textured surface at the outer diameter edge. The protective coating adheres securely to the textured surface at the outer diameter edge to prevent seepage of moisture into the optical disc through the outer diameter edge surface. Thus, an improved optical disc which avoids moisture-caused warpage, corrosion and/or oxidation can be formed.
