Abstract

본 발명은 유전체 구조를 이용한 3층 구조로하여 기록층의 산화를 방지하므로서 C/N비(전송파 대 잡음비)를 좋게하고 장시간 시용수명을 갖게하는데 적당한 광기록 매체에 관한 것으로 투명기판 상에 제1유전체층과 기록층 및 제2유전체층의 순차적으로 적층하여 형성되고, 이때 유전체층의 재질이 AIN, SiN, TiN 중에서 선택하여 이루어지고, 각 유전체층의 두께를 100-500Å로 한 광기록 매체 구조에 관한 기술임.The present invention relates to an optical recording medium suitable for improving the C / N ratio (transmission-to-noise ratio) and long service life by preventing the oxidation of the recording layer by using a three-layer structure using a dielectric structure. Formed by sequentially stacking one dielectric layer, a recording layer, and a second dielectric layer, wherein the material of the dielectric layer is selected from AIN, SiN, and TiN, and a technology of an optical recording medium structure in which the thickness of each dielectric layer is 100-500 Å. being.
