Abstract
A vibration absorber provided on an optical disk drive module of a disk drive for suppressing vibration produced by the optical disk drive module at various speeds. The vibration absorber at least has a body, dampers, elastic members, an actuator and a controller. The body is secured on the optical disk drive module. The dampers elastically and vertically shift on the body. The elastic members are provided on the body for providing elasticity in shifting of the damper. The actuator is provided on the body and coupled to the damper for providing a driving force for the vertical shifting of the damper. The controller controls the driving force outputted by the actuator based on the change in rotational speed of the optical disk drive module, so as to change the elasticity in vertical shifting of the damper to reduce the shifting and corresponding vibration of the optical disk drive module.
