Abstract

본 발명은 브이씨알의 헤드 드럼에 관한 것으로, 일반적으로 사용되고 있는 종래의 헤드는 서로 다른 애지머스를 갖는 2개의 헤드와 스틸 전용 헤드가 있고, 두 헤드중에 하나의 헤드에 바로 인접한 헤드와 반대 애지머스를 갖는 헤드를 첨가하였다.TECHNICAL FIELD The present invention relates to a head drum of V-Cal. The conventional head which is generally used includes two heads having different azimuths and a dedicated steel head, and a head opposite to the head immediately adjacent to one of the two heads. A head with was added.

이러한 헤드구조에서 필드 스틸을 하는 경우에는 테이프의 주행을 정지시킨 후 테이프에 기록된 짝수 필드 또는 홀수 필드중에서 어느 한 필드만을 계속 재생하도록 하였다. 이 경우 헤드 드럼이 1/2 회전한 후에는 테이프의 애지머스와 다른 애지머스를 갖는 헤드가 테이프를 읽게 된다.In the case of field stealing in such a head structure, only one field among the even field or the odd field recorded on the tape is continuously played after the tape stops running. In this case, after the head drum is rotated 1/2, the head having azimuth different from the azimuth of the tape reads the tape.

이 문제를 해결하기 위하여 이 헤드의 바로 옆에 테이프와 같은 애지머스 즉, 바로 옆의 헤드와 반대 애지머스를 갖는 헤드를 부착해 스틸 전욜 헤드로 사용하였다. 즉, 180°의 사이를 두고 반대 애지머스를 갖는 두개의 헤드가 있고 둘 중 하나의 헤드 옆에 2H 정도의 사이를 두고 다른 애지머스를 갖는 헤드를 갖고 있다.To solve this problem, a tape-like azimuth, that is, a head having an azimuth opposite to the next one, was used as the steel head. That is, there are two heads with opposite azimuths between 180 ° and one head with another azimuth with about 2H next to one of the heads.

그러나 상기와 같은 헤드의 구조는 필드 스틸 방식의 경우 하나의 프래임을 구성하기 위해 필요한 짝수 필드와 홀수 필드 두개의 필드중에 하나만을 재생할 수 밖에 없으므로 화면이 단지 하나의 필드로만 구성되었다. 따라서 정상 속도 재생에 비해 화질이 상당히 열화되었다.However, the structure of the head as described above can only play one of the two fields, the even field and the odd field required to form one frame. As a result, the picture quality deteriorated considerably compared to normal speed playback.

이에 따라 본 발명은 상기와 같은 종래 헤드의 구조에 따르는 결함을 감안하여 헤드 드럼의 축 방향으로 서로 같은 애지머스를 갖는 2개의 헤드를 나란히 배열하여 테이프의 정지상태에서 짝수 필드와 홀수필드를 재생할 수 있도록 창안된 것이다.Accordingly, the present invention allows two heads having the same azimuth to be arranged side by side in the axial direction of the head drum in consideration of the defects of the conventional head structure as described above, so that even and odd fields can be reproduced in the stationary state of the tape. It was created to be.
