摘要: A metal film is deposited on a photoresist layer having information-dependent pits, and first of low surface energy the to thereby provide master for making stamper blank. radiation curing resin energy, then transparent plate acrylic placed resin, which hardened by exposure such as ultraviolet through plate. The are separated unitary blank from master. second form stamper. films made polymerized octafluorobutane serve allow information storage discs be released clear stamper, respectively.
