摘要： A disk drive including a motor that rotates a disk, an auto-balancer connected to a rotating portion of the motor, a base secured to the motor and connected to an external member via a first elastic member, and a dynamic vibration absorber connected to the base via a second elastic member. When the disk makes a whirling motion while being rotated by the motor, a phase angle of 120 degrees to 180 degrees is formed between a direction that is pointed from a whirling center axis toward a center of mass of the disk and a direction that is pointed from the whirling center axis toward the center of mass of the auto-balancer.

摘要： The swing centers of guide shafts in inclination adjustment of an optical head are set to be on a plane which is perpendicular to a predetermined radial direction of an optical disk and has thereon the rotation axis of a disk motor. When the inclination adjustment of the optical head is conducted, relative gap variation between the optical head and the optical disk does not occur, and the inclination adjustment is realized within a movable range of an objective lens. The inclination angle of the optical head in a radial direction of the optical disk is adjusted by simultaneously moving upward or downward ends of two guide shafts, and the inclination angle of the optical head in a tangential direction of the optical disk can be adjusted by moving upward and downward one end of at least one of the guide shafts.
摘要翻译：光头的倾斜调整中的导向轴的摆动中心设置在与光盘的规定的径向正交的平面上，并且具有盘式电动机的旋转轴。当进行光头的倾斜调节时，不会发生光头与光盘之间的相对间隙变化，并且在物镜的可移动范围内实现倾斜调节。通过同时移动两个导向轴的上下端来调整光学头在光盘的径向上的倾斜角度，并且可以通过移动来调节光学头在光盘切向方向上的倾斜角度至少一个导向轴的上下一端。
