Abstract

본 발명은 단파장용 광자기 디스크 기록매체에 관한 것으로, 좀 더 구체적으로, 기판상에 보호막, 기록층, 재생층, 기록층, 보호막 및 반사막이 순차적으로 적층된 3층 기록막의 광자기 기록매체에 있어서, 상기 기록층과 재생층 사이 및 상하에 Co/Pd막을 적층시켜 상기 막들 사이에서의 상호 확산 및 산소침투를 방지하여 신뢰성을 향상시키고, 광자기 디스크의 수명을 향상시킨 광자기 기록매체에 관한 것이다.The present invention relates to a short-wavelength magneto-optical disk recording medium, and more particularly, to a magneto-optical recording medium of a three-layer recording film in which a protective film, a recording layer, a reproduction layer, a recording layer, a protective film, and a reflective film are sequentially stacked on a substrate. The present invention relates to a magneto-optical recording medium in which a Co / Pd film is laminated between the recording layer and the reproduction layer and above and below to prevent mutual diffusion and oxygen penetration between the films, thereby improving reliability and improving the life of the magneto-optical disk. will be.
