Abstract

단일의 픽업계만으로 레크모니터를 실현한다.
기록용과 재생용의 버퍼메모리가 설치되고 신호처리계에서는 기록데이터가 기록용 버퍼메모리에 라이트되는 속도보다도 빠른속도로 이 버퍼메모리에서 데이터가 리드되어서 디스크상에 데이터가 라이트된다(제18도 A,B). 다음의 데이터가 디스크상에 라이트될까지의 사이, 직전에 라이트된 데이터가 이 라이트속도와 같은 속도로 재생되어서 재생용 버퍼메모리에 라이트됨과 동시에(동일도면C) 이 버퍼메모리보다 1배속으로 데이터를 리드하면서 레크모니터를 행한다(동일도면D). 이와같이 고속으로 디스크에의 데이터라이트와 디스크로부터의 데이터리드를 행함으로써 단일의 픽업계만으로 레크모니터가 가능하게 된다.
