    • An objective lens actuator has a fixed block fixedly mounted on a movable base and a movable block movable with respect to the fixed block in focusing directions toward and away from recording surfaces of the disc-shaped recording mediums and tracking directions which are substantially radial directions of the disc-shaped recording mediums. A first objective lens is mounted on the movable block for focusing a first laser beam onto the recording surface of a digital versatile disc or a compact disc. A second objective lens is mounted on the movable block for focusing a second laser beam, which has a wavelength shorter than the first laser beam, onto the recording surface of a Blu-ray Disc. The first objective lens and the second objective lens are spaced from each in a tangential direction of recording tracks on the disc which is perpendicular to the focusing directions and the tracking directions. The first or second objective lens has a center positioned on a line which passes through the center of the disc and which extends in the radial directions of the disc. The first objective lens has a center positioned on a line which passes through the center of the second objective lens and which extends in the tangential direction.
    • 物镜致动器具有固定地安装在可移动基座上的固定块和相对于固定块移动的可移动块,聚焦方向朝向和离开盘状记录介质的记录表面,并且跟踪方向基本上是径向的 盘状记录介质。 第一物镜安装在可移动块上,用于将第一激光束聚焦到数字通用盘或光盘的记录表面上。 第二物镜安装在可移动块上,用于将具有比第一激光束短的波长的第二激光束聚焦到蓝光盘的记录表面上。 第一物镜和第二物镜沿盘垂直于聚焦方向和跟踪方向的记录道的切线方向各自间隔开。 第一或第二物镜具有定位在穿过盘的中心并且沿盘的径向方向延伸的线上的中心。 第一物镜具有定位在穿过第二物镜的中心并沿切线方向延伸的线上的中心。
