Abstract

본 발명은 상변화형 광디스크를 개시한다. 기판상에 제1유전체막, 기록막, 제2유전체막 및 반사막이 차례로 형성되어 있는 상변화형 광디스크에 있어서, 상기 제1유전체막과 기록막 사이 및 제2유전체막과 기록막 사이에 실리콘 질화물로 형성한 결정화 촉진막을 더 포함하는 본 발명의 상변화형 광디스크는 기록/소거 반복성을 저하시키지 않으면 고속 소거가 가능하다.The present invention discloses a phase change type optical disc. A phase-change type optical disk in which a first dielectric film, a recording film, a second dielectric film, and a reflective film are sequentially formed on a substrate, characterized in that a silicon nitride film is formed between the first dielectric film and the recording film, The phase change type optical disc of the present invention, which further includes the crystallization promoting film formed of the crystallization promoting film, can perform high-speed erasing without deteriorating the write / erase repeatability.
