    • The apparatus and methods of the present invention provide for a biaxial actuator, an optical pickup device, and an information optical processing device, in which the biaxial actuator is favorably mounted using a single structure. The mounting structure includes first fastening portions protruding from a bottom plate affixed to a substrate. Connecting portions are provided in the first fastening portions through first stress concentration points. The connecting portions are also provided in second fastening portions through second stress concentration points. A mounting portion is provided between the second fastening portions and yokes are formed on the bottom plate to establish a magnetic circuit. A fixing portion of the biaxial actuator is mounted on the mounting portion. By deforming each stress concentration point, a reference state of the objective lens can be determined at an arbitrary position.
    • 本发明的装置和方法提供了双轴致动器,光学拾取装置和信息光学处理装置,其中使用单一结构有利地安装双轴致动器。 安装结构包括从固定到基底的底板突出的第一紧固部分。 连接部分通过第一应力集中点设置在第一紧固部分中。 连接部分还通过第二应力集中点设置在第二紧固部分中。 在第二紧固部之间设置有安装部,并且在底板上形成轭,以建立磁路。 双轴致动器的固定部分安装在安装部分上。 通过使每个应力集中点变形,可以在任意位置确定物镜的基准状态。
