    • The present invention provides a method for adjusting the mechanical error of an optical disc reading device. The optical disc reading device consists of a driving device and an optical pickup. The driving device has a base plate for supporting and rotating an optical disc. The method consists of moving the optical pickup to surface of optical disc, the optical pickup emitting two tracking light spots onto the surface, and the optical pickup reciprocally moving relative to the surface. Next, the optical pickup reads reflected signal of two tracking light spots for generating a track crossing signal. By using the track crossing signal, the method adjusts position of optical pickup relative to the base plate.
    • 本发明提供一种调整光盘读取装置的机械误差的方法。 光盘读取装置由驱动装置和光学拾取器组成。 驱动装置具有用于支撑和旋转光盘的基板。 该方法包括将光学拾取器移动到光盘的表面,光学拾取器将两个跟踪光点发射到表面上,并且光学拾取器相对于表面往复运动。 接下来,光学拾取器读取用于产生轨道交叉信号的两个跟踪光点的反射信号。 通过使用轨道交叉信号,该方法调整光学拾取器相对于基板的位置。
