Optical recording medium

Abstract

An optical recording medium capable of reproduction in accordance with the CD standard is provided. The medium includes a reflective thin film of Ag or similar element, an intermediate thin film of Zn or similar element, and a low-melting thin film of Te or similar element wherein light irradiation causes the reflective thin film element and the low-melting thin film element to diffuse into each other to form an alloy or compound of reduced reflectivity. It is possible to determine through simulation a combination of atoms of the respective thin films which form a cluster having HOMO where electrons in the reflective thin film atoms and electrons in the low-melting thin film atoms do not form a hybrid orbital and LUMO where electrons in the reflective thin film atoms and electrons in the low-melting thin film atoms form a hybrid orbital.
