Method of manufacturing dies for pressing optical disks

A method for manufacturing an optical disk die, comprising the steps:

• illuminating a laminated disk with a laser beam, the disk including--
• (a) a substrate;
• (b) an overlying heat sensitive layer;
• (c) a reflective layer deposited on the hat sensitive layer, the illumination being directed through the substrate and reflected from an internal surface of the reflective layer, causing ablated micro-pits to form in the heat sensitive layer;
• removing the reflective layer;
• depositing a first metallic layer on the pitted heat sensitive layer, the metallic layer following contours of the micro-pits;
• depositing a second metallic layer over the first metallic layer, the second metallic layer having an interface with the first metallic layer which duplicates a pattern of the micro-pits;
• and
• separating the deposited second metallic layer from a remainder of the laminated disk thereby forming a die.
