Abstract
본발명은 백코팅층, 베이스필름, 반사층, 기록층 및 소거층으로 이루어지는 유기광기록 테이프로써, 기록층은 탄성수지에 대해 색소 2-40wt%, 액정 2-50wt%가 첨가되어 이루어지며, 기록층이 탄성수지 색소 및 액정으로 이루어져 기록시 범프생성과 함께 액정의 배향이 흐트러져 범프의 산란을 증가시킴으로써 낮은 범프로도 높은 C/N비를 얻을수 있어 기록층의 두께가 0.5~2μm로 얇게되어, 전체 테이프의 크기가 줄어들게 되어 그만큼 기억용량을 증대시키고, 소거시에는 써멀패드와 자계발생수단에 의해 액정의 배열을 정렬시켜 반복사용에 따른 C/N 비를 증대시키는 것이다.
