Master for optical element replication |
摘要 |
A master for the replication of optical elements is prepared by the steps of: (a) focusing an information modulated energy beam on a phase-change optical recording layer so as to form a pattern of two different phases in said layer corresponding to said information; and (b) selectively etching away one of said two different phases so as to form a relief pattern corresponding to said information. The master so made can be used directly as the stamper in the injection molding process or the 2-P process for the replication of optical elements.
