摘要： An objective lens actuator is provided in which an objective lens is hardly affected by a higher vibration mode and a gain crossover frequency can be increased even when the objective lens is disposed at the end of a lens holder. Between the optical axis of an objective lens 11 and an end 12a on a lens holder 12 for holding the objective lens 11, a notch 20 is provided as a discontinuous portion having discontinuous stiffness in parallel with a focusing direction. With this configuration, the position of the node of a tertiary vibration mode exhibiting unstable control characteristics can be brought close to the position of the objective lens 11 and the influence of a higher vibration mode can be avoided.

摘要： In an objective lens actuator of an optical disk drive and the like, variations in the fixed end positions of wires serving as suspensions are reduced and tilt characteristics are improved. Terminal plates 20 fixed to a lens holder are tilted relative to wires 13 for supporting the lens holder with elasticity, and are soldered at the edges of the terminal plates 20, so that variations in the fixed end positions of the wires 13 are reduced.
摘要翻译：在光盘驱动器等的物镜致动器中，减少了用作悬架的线的固定端位置的变化，并提高了倾斜特性。固定在透镜保持架上的端子板20相对于电线13倾斜，用于支撑透镜保持器的弹性，并且在端子板20的边缘焊接，使得电线13的固定端位置的变化减小。
