Claims (1)

기록매체를 길이방향으로 주행시키기 위한 캡스틴과 원주면상에 정보헤드들을 부착한 드럼을 포함하고 있는 헬리컬스캔닝방식 재생장치의 서보제어방법에 있어서, 모드 절환 요구시 절환될 모드를 판단하여 해당절환 모드별 드럼의 회전속도 오차량을 산출하고, 상기 드럼의 회전속도량에 의해 드럼속도제어용 구동신호의 크기를 설정하여 드럼을 회전속도를 제어하면서 캡스틴의 회전속도가 안정화 되는가 검사하는 드럼속도보상과정과, 상기 드럼속도보상과정에서 캡스틴의 회전속도가 안정화 되었을 대 모드별 정상제어속도로 드럼의 회전속도를 제어하는 정상드럼 제어과정을 포함함을 특징으로 하는 드럼제어방법.A servo control method of a helical scanning type playback apparatus including a capstin for driving a recording medium in a longitudinal direction and a drum having information heads mounted on a circumferential surface thereof, wherein the mode to be switched is determined by determining a mode to be switched when a mode switching request is made. Drum speed compensation for calculating whether the rotation speed of the drum for each mode is calculated and capstan's rotation speed is stabilized while controlling the drum's rotational speed by setting the magnitude of the drive signal for controlling the drum speed by the drum's rotational speed. And a normal drum control process of controlling the rotational speed of the drum at a normal control speed for each mode when the rotational speed of the captain is stabilized in the drum speed compensation process. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
