    • An optical pickup and an optical recording and/or reproducing apparatus adopting the same are provided. The optical pickup includes an optical unit, first and second objective lenses, and an optical path switching unit. The optical unit illuminates light onto an information storage medium and receives light reflected from the information storage medium to detect an information signal and/or an error signal. The first and the second objective lenses focus incident light to form a light spot on an information storage surface of the information storage medium. The optical path switching unit selectively directs the light incident from the optical unit to one of the first and second objective lenses. In the optical pickup, since the light quantity directed to a plurality of objective lenses may be maximized, optical efficiency is increased and thus high-speed operation may be attained.
    • 提供了一种光拾取器和采用该拾取器的光学记录和/或再现装置。 光学拾取器包括光学单元,第一和第二物镜以及光路切换单元。 光学单元将光照射到信息存储介质上并接收从信息存储介质反射的光以检测信息信号和/或误差信号。 第一和第二物镜聚焦入射光以在信息存储介质的信息存储表面上形成光斑。 光路切换单元将从光学单元入射的光选择性地引导到第一和第二物镜之一。 在光学拾取器中,由于可以使指向多个物镜的光量最大化,所以光学效率提高,因此可以实现高速运转。
