Claims (1)

  1. 기록 정보를 소정의 주파수 변조하고, 이 주파수 변조 신호에 의해서 레이저빔을 단속 제어하고, 이 레이저 빔을 써서 일정한 각 속도로 회전시키고 있는 광 디스크에 기록을 행하게 한 광 디스크 장치에 있어서, 상기 광 디스크의 상기 소정의 주파수 변조에 의한 기록 한계보다 내주측에 상기 레이저빔을 이동해서 기록을 행함과 더불어, 이 내주측의 기록에선 상기 기록 정보의 주파수 특성을 제한하며 또한, 상기 주파수 변조의 반송 주파수를 낮게하고, 이 제한 및 주파수의 저하를 상기 기록 한계의 위치로의 접근에 따라서 서서히 상기 소정의 주파수 변조의 특성에 접근 시키도록 한 것을 특징으로 하는 광디스크 장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
