제6도는 제3도에 도시된 기록/재생 장치에서 사용되는 광학 디스크의 개략적 평면도.

Claims (4)

  1. 데이타 기록 방법에 있어서, m비트 데이타가 n비트 데이타로 변환되며 여기서 m 및 n은 실정수로서 m＜n이며, p비트 병합비트 n비트 데이타와 n비트 데이타의 교번하여 연속되는 "0"의 수 사이로 삽입되며, p비트 병합비트는 선정된 수 d이상이며 d보다 큰 수 k이하가 되는 방식으로, 기록되는 데이타가 변조되며, 여기서 기록은 하나의 유니트로서 각각의 선정된 데이타 블록에 기초하여 수행되는 것을 특징으로 하는 데이타 기록 방법.
  2. 제1항에 인용된 데이타 재생 방법에 있어서, 상기 병합 비트 삽입 단계는 n비트 데이타 사이에 기록 데이타의 디지탈 합산값과 일치하는 비트 패턴의 병합 비트를 삽입하며, 하나의 유니트로서 각각의 데이타 블록에 대해 데이타 제어를 사용하기 위해 하나의 유니트로서 각각의 데이타 블록에서 DSV를 리셋팅하는 단계를 구비하는 것을 특징으로 하는 데이타 재생 방법.
  3. 매체 위에 미리 기록된 데이타 재생 방법에 있어서, 기록 매체로부터 기록된 데이타를 복조하며 재생할 때, m비트 데이타가 n비트 데이타로 변환되며, 여기서 m 및 n은 실정수로서 m＜n이며, p비트 병합비트 n비트 데이타와 n비트 데이타의 교번하여 연속되는 "0"의 수 사이로 삽입되며, p비트 병합 비트는 선정된 수 d이상이며 d보다 큰 수 k이하가 되는 방식으로, 기록 데이타가 변조되는 기록된 데이타를 갖는 기록 매체상에 미리 변조 및 기록되며, 상기 방법은, 기록된 데이타를 재생하며, 처리중에, 병합비트의 비트 패턴이 변조 규칙과 일치하는지를 결정하며 병합 비트 부근에서 재생된 데이타가 재생된 데이타와 함께 하는 에러가 되는 변조 규칙과 일치하지 않는지를 나타내는 에러가 되는 변조 규칙과 일치하지 않는지를 나타내는 에러 검출 데이타를 출력하는 단계를 구비하는 것을 특징으로 하는 데이타 재생 방법.
  4. 기록된 데이타를 갖는 데이타 기록 매체에 있어서, 상기 데이타는 m비트 데이타가 n비트 데이타로 변환되며, m 및 n은 실정수로서 m＜n이며, p비트 병합비트 n비트 데이타와 n비트 데이타의 교번하여 연속되는 "0"의 수 사이로 삽입되며, p비트 병합비트는 선정된 수 d이상이며 d보다 큰 수 k이하가 되는 방식으로기록된 데이타가 변조되며, 기록 데이타의 디지탈 합산값과 일치하는 비트 패턴의 병합 비트는 n비트 데이타 시이로 삽입되며 SDV는 하나의 유니트로서 각각의 데이타 블록에 대한 데이타 제어를 이용하기 위해 하나의 유니트로서 각각의 데이타 블록에서 리셋트 되는 것을 특징으로 하는 데이타 기록 매체.
