Abstract

본 발명은 광자기 기록매체에 관한 것으로. 기판(1)상에 제 1유전체막(2), 기록막(3), 제2유전체막(4) 및 반사막(5)이 차례로 성막된 구조로 된 광자기 기록매체에 있어서, 상기 제1 및 제 2유전체막의 구조가 기록막에 접하는 층은 Si_xN_1-x(2',4')기판 및 반사막에 접하는 충은 Si₃N₄(2,4)의 이층으로 이루어진 것을 특징으로 한다.The present invention relates to a magneto-optical recording medium. A magneto-optical recording medium having a structure in which a first dielectric film 2, a recording film 3, a second dielectric film 4, and a reflective film 5 are formed on a substrate 1 in this order. The layer in which the structure of the second dielectric film is in contact with the recording film is characterized in that the layer in contact with the Si _x N _1-x (2 ', 4') substrate and the reflecting film is made of two layers of Si ₃ N ₄ (2,4).
