GLASS SUBSTRATE FOR INFORMATION RECORDING MEDIUM AND METHOD FOR MANUFACTURING SAME

摘要

A method for efficiently manufacturing a glass substrate (21) with a texture (23) composed of projections (24) having a uniform height is disclosed. The method comprises a step (S14) wherein a glass plate (21a) is provided with a surface layer (27) having a lowered chemical resistance, a step (S15) wherein a texture with a plurality of projections having upper portions within the surface layer is formed, and a step (S16) wherein the surface layer is selectively removed.
