Abstract

A multi-information-layer optical disk system using electrochromism for layer selection has been proposed and studied. Promising advantages of the disk are in its large capacity, high sensitivity in recording, and relative simplicity regarding hardware. PEDOT, a polythiophene derivative was selected as an electrochromic material. As a result of our fundamental investigation, DVD-like write/read has been achieved using DVD-RAM disk substrates and optics as DVD on a colored layer.
