Abstract
A deviation adjustment mechanism for spindle motor and pickup head of optical disk drives includes an optical disk drive dock for holding a pickup head and a motor holding seat for holding a spindle motor. The motor holding seat has a retaining flange on one edge. The optical disk drive dock and the motor holding seat are connected by an elastic element to move the motor holding seat in one direction in normal conditions. An adjusting member is provided to press the retaining flange to move the motor holding seat towards another side to adjust the deviation of the spindle motor and the pickup head of the optical disk drive.
