Abstract

본 발명은 DVCR에 있어서 본 발명에 의한 트래킹에러 산출방법은 회전헤드를 사용하여 경사진 트랙에 디지탈신호를 기록 및 재생함에 있어서, 재생시 해당 트랙을 정확하게 트레이스하기 위하여 트랙의 구조적인 배치특성을 이용하여 트래킹에러를 산출함으로써 종래에 사용하던 디지탈신호 검파부를 제거하고도 재생 초기 신속하게 트래킹에러를 산출할 수 있는 장점이 있다.According to the present invention, in the DVCR, the tracking error calculation method according to the present invention utilizes the structural arrangement characteristics of tracks to accurately track the tracks during reproduction in recording and reproducing digital signals on inclined tracks using a rotating head. By calculating the tracking error, the tracking error can be quickly calculated at the initial stage of reproduction even when the digital signal detector used in the prior art is removed.
