Abstract

본 발명은 헬리컬 스캔방식 기록, 재생계가 이용되는 디지탈신호 기록, 재생 시스템 분야에 관한 것으로, 헤드스위칭시 발생하는 노이즈로 인한 에러발생을 방지하고 한 동기블럭을 같은 트랙에 기록하여 동기인식을 통해 에러없이 데이타를 재생하는 것을 기술적 과제로 한다.BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to the field of helical scan type recording, digital signal recording using a reproducing system, and a reproducing system. It is a technical problem to play back data without using it.

따라서 헤드 스위칭으로 인한 노이즈 영향은 트랙의 시작과 끝부분에 더미 데이타를 기록하고, 수신된 원래의 데이타는 그의 부분에만 기록하여 에러를 방지하며, 시스템에서 동기블럭을 부가하여 각 트랙이 일정 정수개의 동기블럭을 기록함에 따라 에러를 방지하는 것을 요지로 한다.Therefore, the noise effect due to head switching records dummy data at the beginning and the end of the track, and the received original data is recorded only at that part to prevent errors, and the system adds a sync block so that each track has a constant number of integers. The point is to prevent errors by recording the sync block.

또한 본 발명은 헬리컬 스캔 방식의 기록, 재생장치, D.VCR, R.DAT 등에 이용되는 것을 용도로 한다.In addition, the present invention is intended for use in a helical scan type recording and reproducing apparatus, D.VCR, R.DAT, and the like.
