<P>PROBLEM TO BE SOLVED: To prevent vibration of an optical component, such as a rising mirror, caused by vibration of an object actuator generated when an optical disk is rotated at high speed, due to reduction in rigidity when an optical base is made thin. <P>SOLUTION: An objective lens actuator and an optical base are connected at least three points.One of the points provided near the rising mirror is disposed near a flat plane passing through a center of an objective lens and perpendicular to the radial direction of the optical disk, to reduce the vibration to be transmitted to the optical base. <P>COPYRIGHT: (C)2011,JPO&INPIT |
