Patent ID: 7886317

Claim:
A vibration absorber provided on an optical disk drive module of a disk drive for suppressing a vibration produced by the optical disk drive module at various speeds, the vibration absorber comprising: a body secured to the optical disk drive module; at least one damper elastically and vertically shifting on the body; at least one elastic member provided on the body for providing elasticity in shifting of the damper; an actuator provided on the body and coupled to the damper for providing a driving force for the vertical shifting of the damper, wherein the actuator penetrates a vertical part of the body and can be vertically slid along the vertical part, and the actuator includes a coil and a magnet, in which the magnet is attached to the body and the coil is connected to the damper; and a controller for controlling the driving force by the actuator based on a 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 corresponding to the vibration of the optical disk drive module.
