Abstract
본 발명은 land와 groove에 적층구조를 달리하여 두개의 레이져빔을 상,하에 설치하여 정보저장능력을 증대시키는 광자기디스크 구조에 관한 것으로, land와 groove 폭이 동일한 기판의 land와 groove상에 각각 land 기판/반사막/유전체막/기록막/유전체막/보호막의 구조와 groove 기판/유전체막/기록막/유전체막/반사막/보호막의 구조로 이루어짐을 특징으로 하는 광자기디스크에 관한 기술이다.The present invention relates to a magneto-optical disk structure for increasing information storage capacity by installing two laser beams up and down by varying a lamination structure in land and groove, respectively, on land and groove of a substrate having the same land and groove width. The present invention relates to a magneto-optical disk comprising a structure of a land substrate / reflection film / dielectric film / recording film / dielectric film / protective film and a structure of a groove substrate / dielectric film / recording film / dielectric film / reflective film / protective film.
