Claims (1)

  1. 디스크에 기록된 정보신호를 독출하는 픽업장치에 설치되며 디스크의 반경방향으로 이동가능한 트랙주사수단과, 이 트랙주사수단을 구동하여 이동시키는 이송수단을 구비한 디스크 재생장치에 있어서, 상기 트랙 주사수단의 이동속도를 검출하는 속도검출회로(19)(21)와, 상기 속도검출회로(19)(21)로부터 출력된 신호를 소정의 기준신호와 비교하는 비교회로(18)가 설치되어, 디스크의 트랙비월 조작시 상기 비교주단(18)으로 부터의 출력신호를 근거로 하여 상기 이송수단을 제어하므로써 상기 트랙주사수단을 일정속도로 이동시키게 된 것을 특징으로 하는 디스크 재생장치.
