Deviation adjustment mechanism for spindle motor and pickup head of optical disk drives

A deviation adjustment mechanism for spindle motor and pickup head of optical disk drives to adjust a deviation between a spindle motor and a pickup head of an optical disk drive, comprising:

• an optical disk drive dock for holding the pickup head;
• a motor holding seat for holding the spindle motor being movably mounted onto the optical disk drive dock and including a retaining flange;
• an elastic element having one end fastened to the optical disk drive dock and the other end fastened to the motor holding seat to generate an action force to constantly pull the motor holding seat towards the optical disk drive dock in a first axis direction coaxial to the elastic element;
• an adjusting member movably located on the optical disk drive dock corresponding to the retaining flange, the adjusting member in contact with the retaining flange such that when the position of the adjusting member is changed the adjusting member causes the retaining flange to move so as to alter the relative position of the motor holding seat and the optical disk drive dock in the first axis direction;
• and
• an anchor member connecting the motor holding seat and the optical disk drive dock to fix the relative position of the motor holding seat and the optical disk drive dock.
