20100077415 | Chucking device for a disk - A chucking device for a disk including a turntable on which an optical disk is seated, a housing provided on the turntable in such a manner as to be inserted into a center hole of the optical disk, a chuck pin having an end protruding outwards from the housing so that, when the optical disk is inserted into and released from the chuck pin, the chuck pin reciprocates from the center of the optical disk, a spring elastically forcing the end of the chuck pin outwards from the center of the optical disk, and a spring holder provided slantwise on the chuck pin such that the spring is held thereon so that an elastic force of the spring is applied inclined onto the chuck pin acting towards the direction of the turntable. | 03-25-2010 |
20100146525 | Clamping device for disk - Disclosed herein is a disk clamping device capable of preventing the slipping or eccentricity of an optical disk when it rotates at high speeds. The disk clamping device includes a turntable having a hub which is integrally provided in a central portion thereof and inserted into a central hole of an optical disk. A guide unit is accommodated in the turntable in such a way as to move linearly, and at least portion of the guide unit protrudes outwards from the hub and is supported | 06-10-2010 |
20130140962 | SPINDLE MOTOR - Disclosed herein is a spindle motor including: a shaft; a rotor case coupled to the shaft to rotate integrally with the shaft and including a rotor magnet coupled to an inner portion thereof; a base plate to which the shaft is rotatably coupled; a bearing coupled to an outer peripheral surface of the shaft to rotatably support the shaft; a bearing holder coupled to an outer peripheral surface of the bearing to support the bearing and fixedly coupled to an upper portion of the base plate; and a stator core part coupled to an outer peripheral surface of the bearing holder so as to face the rotor magnet, wherein the bearing has a length of an inner peripheral surface contacting the shaft longer than a length of an outer peripheral surface contacting the bearing holder. | 06-06-2013 |
