    • An optical disk drive for recording information on a recording surface of an optical disk and reading information recorded in the optical disk is provided. The optical disk drive includes a spindle to rotate the optical disk and a carriage movable in parallel with a tracking direction of the optical disk. The carriage includes a laser light source to emit laser light, a collimator lens to convert divergent light into parallel light and is arranged with an optical center thereof being in a farther and offset position with respect to an optical axis of the laser light, a reflecting mirror to receive and deflect the laser light transmitted through the collimator lens in a direction perpendicular to the recording surface of the optical disk, and an objective lens to converge the laser light deflected by the reflecting mirror on a position corresponding to the recording surface of the optical disk.
    • 提供一种用于在光盘的记录表面上记录信息并读取记录在光盘中的信息的光盘驱动器。 光盘驱动器包括用于旋转光盘的主轴和可与光盘的跟踪方向并行移动的滑架。 滑架包括用于发射激光的激光源,将发散光转换为平行光的准直透镜,并且其光学中心相对于激光的光轴位于更远和偏移位置,反射 反射镜,以在垂直于光盘的记录表面的方向上接收和偏转透射准直透镜的激光;以及物镜,将由反射镜偏转的激光会聚在与该光盘的记录表面相对应的位置上 光盘。
