Abstract

본 발명은 디스크 매체상의 나선형 레코드 트랙들이 방사 방향의 다수의존으로 분할되어 디스크가 일정각 속도로 회전되어 구동되거나 회전 및 구동 각 속도가 각 존마다 단계적을 변화하는 경우에, 레코딩/제생된 데이타 율이 단계적으로 변화하는 디스크 레코딩/재생 시스템으로서, 본 시스템은 레코딩/재생된 데이타율을 조절하도록 디스크 매체상의 제 1존과 제 2존 사이의 경계부에 제공된 데이타 율 조절 영역, 제 1존과 제 2존에 걸쳐 계속적으로 레코딩 재생 데이타가 존재하는 경우에 데이타 율 조절 영역을 검출하는 조절 영역 검출 수단과 데이타 율 조절 영역이 검출되는 경우에 레코딩/재생 데이타 추출 PLL 또는 레코딩 기준 주파수 발생 PLL의 주파수를 조절하는 주파수 조절 수단을 포함한다.
