Description

광자기 기록매체Magneto-optical recording media

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제3도는 본 발명에 의한 광자기 디스크의 단면도이고, 제4도는 본 발명 광자기 디스크의 기록회수에 따른 CNR(Carrier to Noise Ratio)의 변화를 나타내는 그래프이며, 제5도는 재생 파우어(power)에 따른 CNR의 변화를 나타내는 그래프로서, (a)는 본 발명에 따른 광자기 디스크에서 나타나는 효과를 (b)는 종래기술에 의한 광지기 디스크에서 나타나는 변화를 도시한 것이다.3 is a cross-sectional view of a magneto-optical disk according to the present invention, and FIG. 4 is a graph showing a change in carrier-to-noise ratio (CNR) according to the recording frequency of the magneto-optical disk of the present invention, and FIG. 5 is a reproduction power. As a graph showing the change of the CNR according to the present invention, (a) shows the effect of the magneto-optical disk according to the present invention and (b) shows the change of the conventional optical fiber disk.
