Abstract

보다 고밀도로 데이타를 기록하도록 배열된 데이타 기록 방법 및 장치가 개시된다. 학습 데이타 발생 회로에 의해 발생된 학습 데이타는 디스크상에 기록되며, 부호간 간섭 측정부에 의해 학습 데이타의 부호간 간섭을 측정하도록 플레이어에 의해 재생된다. 프리-앰퍼시스 보정치 산출회로에서, 상기 측정된 부호간 간섭에 대응하는 프리-엠퍼시스 보정치가 산출된다. 상기 산출의 결과는 기록 엣지 위치 산출회로의 ROM내의 테이블로서 기록된다. 상기 기록엣지 위치 산출 회로는 상기 ROM에서 기록된 테이블에 따라 정보원으로부터 출력된 기록데이타를 처리한다.
