Abstract: PURPOSE: A method for controlling a track jump of an optical disk system is provided to simplify an acting procedure for jumping a track to reduce time required to jump the track. CONSTITUTION: A method for controlling a track jump of an optical disk system includes eight steps. A first step is to judge whether a key signal for a track jump is inputted or not in a reproducing state. A second step is to detect the present track position and detect a distance between the detected track and an object track when the key signal is inputted. A third step is to judge whether an optical picking up unit(110) is arrived to the object track after transferring all of the optical picking up unit so as to correspond to the distance. A fourth step is to detect the present track position when the optical picking up unit is not arrived. A fifth step is to detect a track number remaining in between the present track position of the fourth step and the object track position. A sixth step is to drive a tracking actuator coil so as to correspond to the remaining track number. A seventh step is to judge whether the optical picking up unit is arrived to the object track or not according to the driving of the tracking actuator coil. A eighth step is to stop the driving of the actuator, feed back to the first step, and, repeatedly, perform the above steps when the optical picking unit is arrived.

Filed: 1999-03-17
Abstract: 본 발명은  클램프 회로의 피드백 루프에 의한 발진을  방지할 수 있게 한다.     캐패시터를 통하여 연산증폭기의 제1 반전 입력단자로 영상신호가  입력될 경우,  흑색 레벨 기준신호가 입력되는 비반전 입력단자의 전위보다 제1 반전 입력단자의 전위가  낮기 때문에,  출력단자는  하이 레벨로 되고자 한다.     이에 의해,  베이스가 출력단자에 접속된 NPN 트랜지스터가  온으로 되어,  캐패시터를  충전시킨다.     캐패시터의 충전이 완료됨에 따라,  제1 반전 입력단자의 전위가  제2 반전 입력단자의 전위보다  높아지게 된다.     따라서,  제2 반전 입력단자에 우선권이 부여되어,  출력단자와 제1 반전 입력단자를 접속하는 제1 피드백 루프로부터 출력단자와 제2 반전 입력단자를 접속하는 제2 피드백 루프로  피드백 루프가 전환되게 된다.     이 제2 피드백 루프에는 캐패시터가 접속되지 않기 때문에,  출력에 어떠한 부하 용량도 보이지 않게 되어,  피드백 루프에 의한 발진을  방지할 수 있게 된다.
