摘要： 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.

摘要： A hard disk drive having a vibration reducing damper is disclosed. The hard disk drive is provided with a damper which is interposed between a through hole provided at a cover plate and a screw joined to the upper end of the shaft of a spindle motor, and includes at least one viscoelastic material layer. It is preferable that the damper has a multi-layered structure in which at least one high stiffness layer has relatively higher stiffness and at least one low stiffness layer made of a viscoelastic material has relatively lower stiffness. With the above configuration, the damper restrains vibrations generated by the spindle from being transferred to the cover plate, noises generated by the hard disk drive are reduced, and, in addition, since vibrations generated by the spindle motor are damped, disk fluttering is reduced.

摘要： 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.

摘要： Provided are a magnetic recording medium and a method of manufacturing the magnetic recording medium. The magnetic recording medium includes a substrate, a soft magnetic underlayer formed on the substrate, a texturing layer formed on the soft magnetic underlayer and including a uniform pattern, and a recording layer including magnetic grains and a non-magnetic boundary region isolating the magnetic grains. The magnetic grains and the non-magnetic boundary region of the recording layer are formed into a regular granular structure by segregation according to the regular pattern of the texturing layer. Therefore, a regular granular structure can be formed in the recording layer without a process such as etching of the recording layer, so that the recording density of the magnetic recording medium can be largely improved.

摘要： A self-compensating dynamic balancer restricts vibrations of moving members by regulating movements of the moving members when a main body does not rotate or rotates at a low speed below the natural frequency. The self-compensating dynamic balancer, coupled to a rotating body, includes a main body having a circular race formed around a rotation shaft of the rotating body. A magnet is inserted around the outer circumference of the inner wall of the race. Moving members, which have a plurality of non-magnetic rigid bodies and a plurality of magnetic rigid bodies, are movably disposed in the race. Each of the magnetic rigid bodies is disposed between the non-magnetic rigid bodies. A cover member is coupled to the main body to cover the race. Thus, since mutual magnetic effects between the moving members are removed, the internal vibrations generated due to an eccentric center of mass of the rotating body can be restricted.
