Abstract
A disk player having a self-compensating dynamic ring balancer to restrict internal vibrations due to an eccentric center of gravity of a disk, includes a deck base, a deck plate elastically coupled to the deck base, a buffering member interposed between the deck base and the deck plate, a spindle motor coupled to the deck plate and having a stator, a rotor and a rotational shaft, a turntable installed at the rotational shaft, a clamper, and an optical pickup for recording/reproducing information on/from the disk. A self-compensating dynamic ring balancer is coupled to the spindle motor and positions the center of gravity thereof opposite to that of the disk with respect to the rotational shaft during rotation of the disk. Therefore, the revolution of the rotational shaft of the spindle motor due to the eccentric center of gravity of the disk can be reduced.
