摘要:
A method for calibrating steps of a stepping motor used in an optical disc drive is provided. A pick-up head is moved to an origin of the structure. The pick-up head is moved toward a terminal of the structure by a stepping motor. The steps of the stepping motor are recorded until a counter electromotive force of the stepping motor is detected. A predetermined travel distance of the pick-up head is calculated. If the predetermined travel distance of the pick-up head is different from the maximum distance of the structure, then it is decided that the stepping motor has step error, and the steps of the stepping motor are calibrated.
摘要(中):
提供了一种用于校准在光盘驱动器中使用的步进电机的步骤的方法。 拾起头移动到结构的原点。 拾取头通过步进电机向结构的端子移动。 记录步进电动机的步骤,直到检测到步进电动机的反电动势。 计算拾取头的预定行驶距离。 如果拾取头的预定行驶距离与结构的最大距离不同,则判定步进电动机具有步进误差,并且步进电动机的步骤被校准。
