Abstract

The present work contains results of the investigations of the master disks manufacturing process and the following stamp plating process for compact disk duplication. The salient feature of the process under consideration is the use in a master disks as a photosensitive material of the vacuum deposited organic dye layer, the relief image on which is formed directly in the irradiation-recording process. In the work are considered the master disks manufacturing process. An organic dye is deposited by the thermal vacuum evaporation method. This provides the thickness test of a coating directly during the manufacturing process, the high purity of a photosensitive layer and its very high uniformity in thickness.
