Abstract

본 발명의 1필드의 주요데이타를 한 트랙에 기록해 두었다가 고배속재생시 이 데이타만으로 화면을 구성하도록 한 다이나믹트래킹을 이용한 고배속재생방법에 관한 것이다. 이러한 본 발명은 1필드의 중요한 데이타를 트릭재생데이타로 설정하여 여러트랙중 일부의 트랙에 기록한다. 고배속재생시 다이나믹트래킹헤드는 트릭재생데이타가 실린 트랙만을 읽거나 점프하여 재생된 신호로 화면을 구성한다. 재생장치에서 다이나믹트래킹헤드의 움직임을 제어하는 드라이브신호를 생성할 때 헤드의 높이가 중심위치에서 최소가 되면서 트릭재생트랙을 읽거나 점프하도록 한다. 따라서, 고배속재생시 헤드의 가동범위가 작아지게 되고, 트랙기록패턴 및 헤드의 드라이브신호를 효과적으로 구성하면 고배속까지 노이즈없는 재생이 가능하게 된다.The present invention relates to a high speed reproduction method using dynamic tracking, in which main data of one field of the present invention is recorded on one track and the screen is composed only of this data during high speed reproduction. In the present invention, important data of one field is set as the trick play data and recorded on some tracks of several tracks. During high speed playback, the dynamic tracking head reads or jumps only the track containing the trick play data and configures the screen with the reproduced signal. When the playback device generates a drive signal to control the movement of the dynamic tracking head, the height of the head is minimized from the center position so that the trick playback track is read or jumped. Therefore, the moving range of the head becomes small during the high speed reproduction, and the effective configuration of the track recording pattern and the drive signal of the head enables noiseless reproduction up to the high speed.
