Abstract
Description
Claims (1)
- 엠펙방식으로 기록된 기록매체(2)를 회전시키기 위한 스핀들서보부(8)와, 픽업(6)에 의해 기록매체(2)에서 독취되어 증폭된 데이터를 디지탈신호처리하는 다지탈신호처리부(16), 상기 디지탈신호처리부(16)의 위상에러를 보장하기 위해 로우패스필터(28)와 전압제어발진기(26)로 이루어진 PLL회로, 상기 디지털신호처리부(16)로부터의 데이터를 디코딩하여 유저 데이터를 추출하는 CD-ROM디코더(20), 상기 CD-ROM디코더(20)로부터의 유저데이터를 디코딩하여 출력하는 엠펙디코더(22)를 구비한 엠펙방식 기록매체를 재생하기 위한 재생장치에 있어서, 상기 기록매체(2)의 재생속도를 조절할 수 있는 가변속모드키를 갖춘 키입력부(12)에 가변속모드가 설정되면 상기 디지털신호처리부(16)로 가변속제어 신호를 출력하는 마이컴(10)과, 상기 디지털신호처리부(16)의 위상에러출력을 필터링하는 로우패스필터(24), 상기 로우패스필터(24)의 출력신호에 대응하는 소정의 주파수를 갖는 클럭펄스를 상기 엠펙디코더(22)의 기준클럭으로서 출력하는 전압제어발진기(25)를 구비하여 이루어진 것을 특징으로 하는 엠펙방식 기록매체의 가변속 재생장치.
