Abstract: A disk player having a self-compensating dynamic balancer which can limit internal vibrations generated by an eccentric center of gravity of a disk, and a turntable, a clamper and a spindle motor which incorporate a self-compensating dynamic balancer. The self-compensating dynamic balancer is formed integrally with rotating members in a disk player; that is, a turntable, a clamper and/or a rotor of a spindle motor. The self-compensating dynamic balancer includes at least one race which is integrally formed with the rotating member and rotates around a rotational shaft, a mobile unit which is located in the race to be capable of moving, and a cover member for covering an opening of the race. Thus, internal vibrations occurring due to the eccentric center of gravity of the disk can be effectively limited by the self-compensating dynamic balancer in which the mobile unit is disposed far away from the center of orbital rotation by a centrifugal force during rotation thereof.

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.
