Dynamic Characteristics of an Optical Pick-up Actuator Considering the Motion of a Feeding Deck

피딩데크 운동을 고려한 광픽업 액츄에이터의 동특성 해석

There are a lot of roots of errors in the motion of the optical pickup actuator being one of the most significant components in the CD-ROM drive. Most of the studies recently performed have a tendency to seek fur the causes from an actuator itself. We found the fact that the range of the natural frequencies of a feeding deck and an actuator is close each other through an experiment. This paper present the dynamic characteristics of an actuator affected by the motion of a feeding deck. (omitted)
