Abstract

본 발명은 광테이프의 기록 및/또는 재생장치를 개시한다.
본 발명은 주면에 장공이 형성된 회전드럼내에 광 테이프의 서플라이릴과 테이크업릴을 동축적으로 상하 배열하여 그 광테이프가 그 회전드럼의 외주면에 접촉 이송되게 하고, 그 외주면상의 광테이프의 광을 접속주사하는 광학계를 구비하는 광 테이프의 기록 및/또는 재생장치에 있어서, 상기 광학계⑽가 광원⑾, 이 광원⑾에서 발생된 광을 상기 광테이프(T)상에 저속시키는 대물렌즈⑿, 그 광원⑾과 대물렌즈⑿사이의 광경로상에서 그 대물렌즈⑿의 초점위치를 수직 또는 수평방향으로 변위시키기 위한 광편향수단과, 상기 대물렌즈⑿와 광편향수단 사이의 광 경로상에서 입사광과 분사광을 분리시키는 빔 스프리터⒀ 및 그 분리되는 반사광을 검출하는 광 검출소자⒁로 구성된 점에 그 특징이 있다.
따라서, 고속의 기록 및/또는 재생이 가능하고, 회전드럼의 적은 회전수로 높은 데이터 전송속도를 얻을 수 있고, 기기를 안정화, 소형화, 단순화 시킬수 있으며 소음을 극소화 시킬 수 있게 된다.
