Abstract
1. 청구범위에 기재원 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
광디스크 구동장치의 로딩/언로딩 모터 및 피트모터의 구동을 제어하는 모터 제어회로에 관한 것이다.A motor control circuit for controlling driving of a loading / unloading motor and a pit motor of an optical disc drive device.
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
피트모터 구동부의 기능 및 로딩/언로딩 모터 구동부의 기능을 동시에 수행하는 단일의 모터 제어회로를 구현하기 위한 것이다.It is to implement a single motor control circuit that simultaneously performs the function of the pit motor driver and the function of the loading / unloading motor driver.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
광디스크 구동장치의 모티 제어회로는, 트레이 로딩/언로딩 모터 구동신호 또는 피트모터 구동신호를 발생하는 제어수단과, 트레이 로딩/언로딩 모터 구동 신호 또는 상기 피트모터 구동신호에 응답하는 전압값들을 선택적으로 발생하는 모터 구동 전압값 발생수단과, 상기 선택적으로 발생되는 전압값들을 트레이 로딩/언로딩 모터에 공급하거나 피트모터에 공급하는 전압 공급수단으로 구성한다.The Morty control circuit of the optical disc drive apparatus may be configured to generate a control means for generating a tray loading / unloading motor driving signal or a pit motor driving signal, and selecting voltage values corresponding to the tray loading / unloading motor driving signal or the pit motor driving signal. Motor driving voltage value generating means and voltage supply means for supplying the selectively generated voltage values to a tray loading / unloading motor or a pit motor.
4. 발명의 중요한 용도4. Important uses of the invention
단일의 모터 구동부만을 이용하여 피트모터 및 로딩/언로딩 모터를 동시에 구동시킬 수 있으므로 간단화된 광디스크 구동장치를 구현할 수 있다.Since the pit motor and the loading / unloading motor can be driven simultaneously using only a single motor driving unit, a simplified optical disc driving device can be realized.
