Description

자기재생장치에서의 트래킹(tracking)방식
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명방식의 트랙편차보정동작의 일실시예를 설명하기 위한 회전드럼의 상면도.
제2(a)도, 제2(b)도의 제각기 본 발명방식이 이용되는 트랙편차 검출방식의 일예를 설명하기 위한 파형도.
제3도는 제2도의 신호에 의하여 회전드럼주사제작을 설명하기 위하여 트랙과 회전드럼의 관계를 도시한 도면.
제4(a)도 내지 제4(d)도는 제각기 분할구간에서 재생출력레벨대 제어전압의 관계의 일예를 제각기 도시한 도면.
제5도는 회전헤드를 고주파수에서 요동시킨 트랙편차를 검출하는 경우의 회전헤드주사궤적을 도시한 도면.
제6도는 파일롯 신호가 기록되어 있는 프랙에 대한 회전헤드주사궤적의 일예를 도시한 도면.
제7(a)도∼제7(d)도는 제각기 제6도의 경우, 제각기 분할사이에 있어서, 트랙편차대 제어전압특성을 도시한 도면.

Claims (1)

  1. 자기테이프 길이방향에 대하여 경사한 트랙에 기록 되어 있는 신호를 재생하는 회전헤드를 외부 제어 신호에 응하여 트랙길이 방향에 대하여 직각방향상 변위시키는 헤드 이동기구를 구동하여 트래킹 제어하는 방식에 있어서, 상기 각 트랙을 각각 n개(n은 임의의 정수)의 구간에 분할하여 그 각 분할구간마다에 트랙편차를 각각 검출하여 상기 회전헤드가 주사하고 있는 트랙의 i번째(i는 1∼n)의 분할구간에 있어서는 m트랙(m는 임의의 정수)전의 트랙의 i번째의 분할구간에서 검출한 트랙편차를 작게 하는 제어신호를 상기 헤드 이동 기구에 인가하여 이 회전헤드를 트래킹 제어하는 것을 특징으로 하는 자기재생장치에 있어서의 트래킹방식.
