Claims (1)

광원과, 이 광원으로부터 반사된 빔을 광 테이프 상에 집속하는 대물렌즈와, 그 광 테이프와 대물렌즈 사이의 광경로를 편향시키는 갈바노미터 미러 및 그 광 테이프로 부터 반사되는 반사광을 검출하는 광검출소자를 구비하는 광 테이프의 기록 및/또는 재생장치에 있어서, 상기 광원과 상기 대물렌즈(2) 사이의 광경로상에 소정의 패턴을 가지는 홀로그램소자(1c)가 설치되어 상기 반사광이 다른 경로상으로 회절되게하고, 그 반사광이 회절 위치에 상기 광검출 소자(1b)를 위치시킨 것을 특징으로 하는 광 테이프의 기록및/또는 재생 장치.A light source for detecting a light source, an objective lens for focusing a beam reflected from the light source on an optical tape, a galvanometer mirror for deflecting an optical path between the optical tape and the objective lens, and a light sword for detecting the reflected light reflected from the optical tape. In the recording and / or reproducing apparatus of an optical tape having an output element, a hologram element 1c having a predetermined pattern is provided on an optical path between the light source and the objective lens 2 so that the reflected light is on a different path. And the reflected light is positioned at the diffraction position, so that the photodetecting element (1b) is diffracted. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
