<P>PROBLEM TO BE SOLVED: To provide an optical disk drive device capable of preventing increase of floating amount of a rotation part due to a high speed rotation of an optical disk. <P>SOLUTION: The optical disk drive device includes an optical disk drive motor. The optical disk drive motor has a suction magnet disposed between a rotor holder and a bushing. The rotor holder has a projection formed so that a portion of which is overlapped with the suction magnet in an axis direction. The rotor holder and the bushing are formed of a magnetic material and constitute a part of a magnetic circuit. With this, the optical disk drive motor prevents floating of the rotation part and reduces shaft damage. <P>COPYRIGHT: (C)2013,JPO&INPIT |
