- Abstract
- There are a lot of roots of errors in an motion of the optical pick-up actuator being one of the most significant components in a
CD-ROM drive. Most of the studies recently performed have a tendency to seek for the causes from an actuator itself. This paper
present the dynamic characteristics of an actuator affected by the motion of a feeding deck. The feeding system is modeled as a rigid
body with eight degree-of-freedom. Using Largrange’s equation, we derive the linear equations of motion with respect to the
rectangular coordinate. We found the fact that the ranges of the natural frequencies of a feeding deck and an actuator are close to each
other. And the time responses are also computed by the Newmark method and Runge-Kutta method.
