摘要： PROBLEM TO BE SOLVED: To achieve miniaturization and thinning by obtaining rotational accuracy and rotating performance equal to/higher than those of a ball bearing using the oil-containing bearing of a normal structure, and reducing costs. SOLUTION: Stoppers 110 and 111 are disposed in the opposing surfaces of a magnetic disk 100 having a spindle motor rotating part provided with a magnetic disk 100, a shaft 112 and a hub 114 in a side opposite an incorporating direction. The stoppers 110 and 111 are fixed to the upper surface of a casing 101 or a cover 108, and the spindle motor rotating part regulates a movement in a direction opposite the spindle fixing side incorporating direction caused by external shocks. Thus, the spindle motor rotating part and the spindle motor fixing part can use a spindle motor using the oil-containing bearing not fixed in a rotational axis direction. Therefore, the number of part items is reduced compared with the ball bearing spindle motor, and parts costs and the number of assembling steps are reduced.

摘要： PROBLEM TO BE SOLVED: To provide a disk driving device reduced in vibration of a base and noise of the device caused by a driving reaction force of a carriage. SOLUTION: As a coupling means of a base 1 and VCM, a VCM yoke 2 is inserted between visco-elastic rubber bushes 7 so that a reaction force is not transmitted to the base 1 even if such a driving reaction force occurs as brings about a resonance of a base side member of an actuator. And, the vibrations transmitted to the base 1 are attenuated by adopting such a structure as compresses the rubber bushes 7 by a stud bolt 10 and couples the VCM to the base 1.
