摘要： The invention relates to a pickup unit (1) for reading and/or writing data on a disk (2). The pickup unit (1) comprises a lens (5) in a lens holder (6) which is connected to a frame (7) of the pickup unit (1) by a plurality of elastic support members (8). The lens holder (6) is movable with respect to the disk (2) by bending of the elastic support members (8). The mounting position (9) of each elastic support member (8) at the lens holder (6) is located closer to the disk (2) than the respective mounting position (10) of the elastic support member (8) at the frame (7), as seen in the focusing direction of the lens (5). In this manner the lens holder (6) with the lens (5) is adapted to be brought to an operating distance with respect to the disk (2) which is smaller than the flatness tolerances of the disk (2) without the risk of collisions between the frame (7) and the rotating disk (2).
摘要翻译：本发明涉及用于在盘（2）上读取和/或写入数据的拾取单元（1）。拾取单元（1）包括透镜架（6）中的透镜（5），该透镜架通过多个弹性支撑构件（8）连接到拾取单元（1）的框架（7）。通过弹性支撑构件（8）的弯曲，透镜架（6）可相对于盘（2）移动。位于透镜支架（6）处的每个弹性支撑构件（8）的安装位置（9）比框架处的弹性支撑构件（8）的相应安装位置（10）更靠近盘（2）如在透镜（5）的聚焦方向上看到的那样。以这种方式，具有透镜（5）的透镜架（6）适于相对于盘（2）达到小于盘（2）的平坦度公差的操作距离，而没有碰撞风险在框架（7）和旋转盘（2）之间。

摘要翻译：本发明涉及一种用于在盘（2）上读取和/或写入数据的拾取单元（1）。拾取单元（1）包括通过多个弹性支撑构件（8）连接到拾取单元（1）的框架（7）的透镜保持器（6）中的透镜（5）。透镜支架（6）可通过弹性支撑件（8）的弯曲而相对于盘片（2）移动。每个弹性支撑构件（8）在透镜保持器（6）处的安装位置（9）比框架处的弹性支撑构件（8）的相应安装位置（10）更靠近盘（2）如图7所示，如透镜（5）的聚焦方向所示。以这种方式，具有透镜（5）的透镜保持器（6）适于相对于盘（2）的操作距离小于盘（2）的平坦度公差，而没有碰撞的风险在框架（7）和旋转盘（2）之间。
