摘要： A vibration reduction apparatus of a disk drive is provided. An optical pickup base 10 in which an optical pickup 16 is movably installed is provided. A spindle motor 18 for providing power requiring for rotating a disk is installed at the front end of the optical pickup base 10, and a turntable 20 for mounting a disk is provided at a rotation axis of the spindle motor 18. A vibration reduction body 30 for reducing a vibration generating in the optical pickup base 10 is installed in the optical pickup base 10. The vibration reduction body 30 comprises a fixing device 32 fixedly installed at one side of the optical pickup base 10, a support bar 36 extended from one side of the fixing device 32 and having an elastically deformable cantilever shape, and a vibration proof weight 38 provided at the front end of the support bar 36. Thereby, the vibration reduction body is formed with one module and can be installed at a location having a large vibration response according to a design condition, thereby effectively reducing a vibration.

摘要： A rotor balancer and a disk driver having the rotor balancer are disclosed. The rotor balancer simplifies a construction of an auto balancing unit for automatically correcting a rotation unbalance occurring when a disk is rotated and of a mounting unit for accurately mounting the disk. Further, the rotor balancer reduces noise and vibration. The rotor balancer includes a ball case installed at a rotor for rotating a rotation member. The ball case has a circular racing space of which racing faces have different friction coefficients. The disk driver, having the rotor balancer, includes an insert unit on a turntable which is inserted into a central hole of the disk. A plurality of mounting spring pieces are formed at the insert unit and made of an elastic material so as to elastically support the disk, when it is mounted, so that the disk can be mounted accurately and firmly.

摘要： A disk guide apparatus for an optical disk playback system includes a pinion gear having at least one non-toothed portion, a pair of guide plates respectively having a gear portion being engaged to the pinion gear, and a spring providing an elastic restoration to the guide plates. The apparatus prevents an erroneous insertion of the optical disk and carries out a disk loading/unloading operation by use of minimal parts thereof, thereby realizing a simplified structure and an easy assembly as well as decreasing production cost and improving workability.
