最小偏移加速点检测，聚焦拉拔和层次切割方法以及可执行方法的可选光盘驱动器

MINIMUM DEFLECTION ACCELERATION POINT DETECTION, FOCUS PULL-IN, AND LAYER JUMP METHODS, AND OPTIONAL DISC DRIVE CAPABLE OF PERFORMING THE METHODS
摘要：
Minimum deflection acceleration point detection, focus pull-in, and layer jump methods, and an optical disc drive capable of performing the methods. The method of detecting a minimum deflection acceleration point in an optical disc drive includes rotating a disc loaded in the optical disc drive, detecting a first minimum deflection acceleration point of the disc during one rotation cycle of the disc, and detecting a second minimum deflection acceleration point of the disc during one rotation cycle of the disc. Thus, a stable focus pull-in and layer jump is available.
摘要（中）：

最小偏转加速点检测，聚焦拉入和层跳转方法以及能够执行该方法的光盘驱动器。 检测光盘驱动器中的最小偏转加速点的方法包括旋转装载在光盘驱动器中的盘，在盘的一个旋转周期期间检测盘的第一最小偏转加速度点，并且检测第二最小偏转加速度 在盘的一个旋转周期期间的盘的点。 因此，稳定的聚焦拉入和层跳跃是可用的。
