    • An objective lens driver includes a movable body, a base, a supporting portion, a first multipolar magnet and a second multipolar magnet. The movable body includes an objective lens, a lens holder, and a coil substrate. The coil substrate includes a focusing coil and a tracking coil. The supporting portion allows the movable body to move in a focusing direction and a tracking direction with respect to the base. The focusing direction is parallel to the optical axis of the objective lens, while the tracking direction is perpendicular to the focusing direction. The first and second multipolar magnets sandwich the coil substrate between them. The focusing and tracking coils are arranged as two flat coils on two mutually parallel separate planes so as to overlap with each other at least partially in a direction that is perpendicular to the focusing and tracking directions.
    • 物镜驱动器包括可移动体,基座,支撑部分,第一多极磁体和第二多极磁体。 可移动体包括物镜,透镜保持器和线圈基板。 线圈基板包括聚焦线圈和跟踪线圈。 支撑部分允许可移动体相对于基座在聚焦方向和跟踪方向上移动。 聚焦方向平行于物镜的光轴,而跟踪方向垂直于聚焦方向。 第一和第二多极磁体将线圈基板夹在它们之间。 聚焦和跟踪线圈在两个相互平行的分开的平面上被布置为两个扁平线圈,以便至少部分地在垂直于聚焦和跟踪方向的方向上彼此重叠。

    • In order to obtain a preferred recording/reproducing characteristic in an apparatus for optical disks having higher density, an objective lens drive is provided for driving an objective lens (1) in the optical axis direction, a direction perpendicular to the optical axis, and a tilting direction along the radius of an optical disk, by which operating sensitivity is improved and a stable operating characteristic is realized. Sections of two (7b, 7e) of six fixing portions (7a to 7f) for supporting six support members (6a to 6f) which support a movable part (5), are set lower in stiffness than another sections of the other four fixing portions (7a, 7c, 7d, 7f), thereby improving the operating sensitivity of the movable part (5) and stabilizing the operation of the movable part (5).

    • According to the present invention, a stepping motor driving apparatus having a rotor and a stator in n (an integer equal to or larger than 2) phases for moving a moving body is provided. The stepping motor driving apparatus includes a driver for selectively supplying to the stator a first current pattern for rotating the rotor at a first pitch and a second current pattern for rotating the rotor at a second pitch different from the first pitch based on a drive switching signal. The driver switches the first current pattern and the second current pattern at a point where a torque generated by the first current pattern is equal to a torque generated by the second current pattern and supplies the first current pattern or the second current pattern to the stator.
