Abstract
A vibration-damping mechanism for the drive chassis is configured in such a manner that insulators each are placed in at least three respective predetermined positions of a drive chassis on which a motor and an optical pickup unit are mounted, and a weight plate is floatingly and movably supported on the drive chassis by way of the insulators, wherein the shape of the weight plate is determined based on a predetermined vibration-damping frequency, the at least three respective predetermined positions, and a spring constant of the insulators which are identical to each other.
