Abstract

본 발명은 광자기 디스크의 기록/재생장치에 관한 것이다.
본 발명은, 광자기 디스크에 외부자계를 가하는 자화수단과, 광자기 디스크에 레이저 빔을 접속하는 레이저 조사수단으로서의 광픽업이 연동부재에 의해 연결되어 함께 이송되도록 된 광자기 디스크의 기록/재생장치에 있어서, 상기 연동부재의 일측 하면에 판스프링이 설치되고, 이 판스프링에 상기 자화수단이 마련되어, 상기 자화수단이 상기 판스프링의 탄력에 의해 광자기 디스크에 탄력적으로 접촉되도록 된 점에 그 특징이 있다. 따라서 광자기디스크와 자화수단과의 간격변화로 인한 소거효율의 저하를 방지할 수 있게 되는 등의 이점이 있다.
