摘要:
A method of controlling an optical pick-up head to access an eccentric disk. When a loaded disk is determined as an eccentric disk causing a lens of the optical pick-up head crossing between a first track being close to the inner disk and a second track being close to outer disk, a tracking on position has to be concerned. IF a target track is close to the second track, provide a first force to move the lens a distance toward the inner disk then execute a track on operation. IF the target track is close to the first track, provide a second force to move the lens a distance toward the outer disk then execute a track on operation.
摘要(中):
一种控制光学拾取头以接近偏心盘的方法。 当装载的盘被确定为使得光学拾取头的透镜在靠近内盘的第一轨道和靠近外盘的第二轨道之间交叉的偏心盘时,必须关注位置跟踪。 如果目标轨道靠近第二轨道,则提供第一力将镜头向内盘移动一定距离,然后执行操作轨道。 如果目标轨道靠近第一轨道,则提供第二个力将镜头向外盘移动一定距离,然后执行轨道操作。
