Application of organic dyes to optical disk memory.

Abstract

In optical disk memory system, recording medium is an important element. Organic dyes which were originally used as heat-mode recording media, have also been applied to the optical memory systems.In order to improve the recording characteristics, multilayer structure consisting of dyes and metals have been developed. Recently, the dyes which can be utilized as monolayer structure have been found.In this paper, the designing method of optical characteristics which are important factors for the recording media for optical disk memory and also the recent trend of developing dye materials are described.
