光盘装置跟踪伺服调整方法
摘要：
本发明涉及一种光盘装置跟踪伺服调整方法，其是根据检测光盘内周和外周之间磁道间距，以检测的磁道间距数值为根据，可适时调整外周区域中的跟踪误差伺服系数。本发明构成包括如下步骤：第一步骤：在磁道关闭状态中检测光盘内周和最外周之间磁道间距距离数值；第二步骤：以上面检测的磁道间距距离数值为根据，掌握跟踪误差伺服系数调整所必要的外周区间；第三步骤：在开通磁道状态下，如果读取数据的区域与跟踪误差伺服系数调整所需必要外周区间相应的话，调整相应跟踪误差伺服系数。本发明的跟踪误差伺服系数可以调整，由此，根据光盘开通时内周和外周之间的磁道凹坑差异发生的临近磁道影响可以降低到最小，而且还可以提高跟踪误差伺服的功能。
摘要（英）：

The CD device tracing-servo regulating method is disclosed, in which the spacing between internal circumferential magnetic track and external circumferential magnetic track of CD is detected and the tracing error servo coefficient in external circumferential area can be timely regulated according to the spacing. Firstly, detect the value of the spacing in close-state of the magnetic tracks; According to the value, hold the external circumferential area requested by the regulation of tracing error servo coefficient; In on-state of magnetic tracks, regulate corresponding tracing error servo coefficient if the read data area is correspondent to the requested external circumferential area. Advantage: the effect between near magnetic tracks, resulted by magnetic track depression difference between internal circumference and external circumference can be reduced to minimum, and the function of tracing error servo is raised.
