Description
Claims (3)
- 광디스크를 회전시키는 스핀들모터와, 상기 광디스크로부터 정보를 재생하기 위한 신호를 검출하는 광헤드와, 상기 검출된 신호를 처리하는 프로세서와, 이 프로세서에서 처리된 신호에 따라 상기 스핀들모터가 일정한 선속도로 회전하도록 제어하는 CLV서보가 구비된 스핀들모터 구동장치에 있어서, 상기 CLV서보와 병렬로 위치하여 상기 광헤드가 점프할 때 상기 스핀들모터가 항각속도로 회전하도록 제어하는 CAV서보와, 상기 스핀들모터와 상기 CAV서보 사이에 마련되어 상기 광디스크의 회전속도 신호를 전달하는 궤환루프와, 상기 프로세서를 상기 CAV서보 및 CLV서보와 선택적으로 접속시키는 스위칭수단이 더 구비된 것을 특징으로 하는 스핀들모터 구동장치.
- 제1항에 있어서, 상기 궤환루프와 상기 CAV서보 사이에서 분기되어 상기 CAV서보에 위상동기 신호를 제공하는 PLL회로가 더 구비된 것을 특징으로 하는 스핀들모터 구동장치.
- 제1항에 있어서, 광헤드의 재생동작 중에는 상기 프로세서를 상기 CLV서보에 접속시키고, 광픽업의 점프동작 중에는 상기 CAV서보에 접속시키는 것을 특징으로 하는 스핀들모터 구동장치.
