Actuator for pickup, pickup device, recording medium drive device, and method of manufacturing actuator for pickup
Abstract:
Provided is an actuator for a pickup, in which end parts of a plurality of suspensions (550A to 550F) of five or more are positioned on a virtual circle (X) formed on a plane by being projected onto the plane including both a focusing direction and a tracking direction. A rolling center (O) defined as a center of the virtual circle (X) is made to coincide with all three, two, or one of a center (Os) of the gravity of a lens holder (600), a center (Os) of the drive force of the lens holder (600), and a center (Os) of the translational force of the suspensions (550A to 550F). Since the rolling center (O) coincides with all three, two, or one of those centers (Os), a rotational moment is not generated on the lens holder (600) and, therefore, generation of unnecessary resonance can be prevented.
