Abstract

본 발명은 기록매체의 갭영역에 기록된 트렉킹기준신호에 따라 캡스턴모터를 구동제어하는 디지탈브이씨알의 트랙킹제어장치에 관한 것으로, 회전헤드를 이용하여 데이터포맷의 갭영역에 디지탈변조를 행하지않은 트렉킹기준신호를 기록하여 두고, 재생시 고정헤드를 통해 이 트렉킹기준신호를 검출하고, 검출된 트렉킹기준신호의 엔벨로프양에 따라 트랙킹동작을 제어한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital VLC tracking control device for driving and controlling a capstan motor in accordance with a tracking reference signal recorded in a gap area of a recording medium. The reference signal is recorded, and during reproduction, this tracking reference signal is detected through the fixed head, and the tracking operation is controlled according to the envelope amount of the detected tracking reference signal.

따라서, 본 발명은 정상속도의 재생을 물론 고배속으로 재생하더라도 원활하게 트렉킹동작을 수행할 수 있다. 또한 트렉킹제어를 위하여 콘트롤 신호를 기록하기 위한 콘트롤트랙을 형성할 필요가 없으며, 기록데이타에 파일럿신호를 중첩함에 따라 신호처리가 복잡해지는 것을 줄일수 있는 잇점이 있다.Therefore, the present invention can smoothly perform the tracking operation even at the normal speed and at high speed. In addition, it is not necessary to form a control track for recording a control signal for tracking control, and there is an advantage that signal processing can be reduced by superimposing pilot signals on recording data.
