    • An optical disc device includes a first optomechanical mechanism, a second optomechanical mechanism, and a positioning mechanism. The first optomechanical mechanism is located under an optical disc insertable into the optical disc drive to optically access a bottom surface of the optical disc. The second optomechanical mechanism is located over the optical disc insertable into the optical disc drive to optically access a top surface of the optical disc. The positioning mechanism is to precisely locate the second optomechanical mechanism over the optical disc for optically accessing the top surface of the optical disc and to prevent the second optomechanical mechanism from interfering with movement of the optical disc during insertion and removal of the optical disc into and from the optical disc drive.
    • 光盘装置包括第一光机械机构,第二光机械机构和定位机构。 第一光学机械机构位于可插入到光盘驱动器中的光盘下面以光学地访问光盘的底表面。 第二光学机械机构位于可插入到光盘驱动器中的光盘上,以光学地访问光盘的顶表面。 定位机构是精确地定位光盘上的第二光机械机构,用于光学地访问光盘的顶表面,并且防止第二光机械机构在将光盘插入和移出光盘时干扰光盘的移动, 从光盘驱动器。
