Abstract: 대물렌즈가 탑재되는 보빈과; 보빈을 베이스에 대하여 움직임 가능하게 지지하는 서스펜션과; 보빈 및 베이스에 설치되는 자기 회로;를 포함하는 고감도 광픽업 액츄에이터 및 이를 채용한 광 기록 및/또는 재생기기가 개시되어 있다. 
     자기 회로는, 보빈의 양측면과 마주하여 위치되도록 베이스에 설치되며, 적어도 일부 영역이 트랙킹 방향으로 서로 나란하게 배열되는 구조로 된 제1 내지 제3자석영역을 구비하며, 제1 및 제3자석영역이 각각 가운데에 위치된 제2자석영역과 인접하며 제2자석영역과 반대 극성으로 착자된 한쌍의 자석과; 보빈 둘레에 권선되고, 제2자석영역과 상호 작용하는 포커스 코일과; 자석과 마주하는 보빈의 측면에, 트랙킹 방향으로 서로 나란한 두 변이 트랙킹 제어를 위한 유효 코일로서 사용되도록 배치된 복수의 트랙킹 코일;을 포함하는 것을 특징으로 한다. 
     개시된 바에 따르면, 트랙킹 코일의 두 변을 트랙킹 제어에 사용하므로, 고감도 트랙킹을 실현할 수 있다.
