Abstract

본 발명은 브이씨알의 재생장치에 관한 것으로, 특히 트윈 헤드(Twin Head)의 물리적 및 전기적 특성에 의해 재생단계의 초단에서 신호의 결손이 발생하는 것을 방지하도록 하는 브이씨알의 초단 재생 장치에 관한 것으로, 종래의 휘도 재생계에 대한 기술사항은 재생되는 신호의 윤곽강조에는 효과가 있지만 저역 및 고역 특성의 구현에는 구성상의 문제점이 따르게 되고, 또한 슈퍼 헤드에 의한 재생장치는 테이프의 자성특성과 헤드의 전기적 특성이 매칭될 경우에는 고화질의 재생 충실도를 기대할 수 있지만, 일반적인 헤드를 사용한 재생장치와는 기록 규격이 다르므로 재생 호환성이 문제점이 따르게 된다.TECHNICAL FIELD The present invention relates to an apparatus for regenerating V-Cal, and more particularly, to an apparatus for regenerating V-Cal to prevent signal loss from occurring at the beginning of the regeneration phase due to the physical and electrical characteristics of the twin head. However, the conventional technology of the luminance reproducing system is effective in enhancing the contour of the reproduced signal, but the implementation of the low and high frequency characteristics is accompanied by a configuration problem. When the electrical characteristics are matched, high fidelity reproduction fidelity can be expected. However, since the recording standard is different from that of a general head reproducing apparatus, reproduction compatibility is problematic.

따라서, 본 발명은 재생시에는 드럼의 채널당 각기 특성이 다른 두 개의 헤드 즉, 트윈 헤드에 의해 트랙의 데이타를 주파수 특성에 맞도록 읽어내고, 이 헤드의 기구적인 위치 차이에 의해 발생하는 지연성분을 보정하거나, 헤드의 기존 헤드코일외에 또다른 권선수를 갖는 헤드코일을 추가함으로써 고화질 기록 및 재생이 가능 하도록 하는데 하나의 목적이 있다.Therefore, in the present invention, the track data is read out according to the frequency characteristics by two heads having different characteristics per channel of the drum, that is, the twin heads during reproduction, and the delay component caused by the mechanical position difference of the heads is corrected. In addition, one purpose is to enable high-quality recording and reproduction by adding a head coil having another winding number in addition to the existing head coil of the head.
