System and method for optical disc drive adjustment

A system for adjusting optical disc drives, comprising:

• an optical disc drive component, comprising an optical pickup head, a rotating disc, and a reflector located on the rotating disc;
• a monitor;
• a switch box, coupled to the monitor;
• an autocollimator, coupled to the switch box, located above the rotating disc, for sensing a tilt angle of a reflector on the rotating disc, and transmitting signals to the switch box to display a first bright spot on the monitor;
• a reader, reading a bar code of the optical pickup head;
• a host, coupled to the reader and switch box, calculating the tilt angle of the optical drive component according to the bar code content and transmitting signals to the switch box to display a second bright spot on the monitor;
• and
• an adjustment mechanism, adjusting the optical drive component and switching signals from the autocollimator and the host using the switch box to, enable the first bright spot from the autocollimator to coincide with the second bright spot from the host.

A method for adjusting optical disc drives, comprising steps of:

• sensing a tilt angle of a rotating disc located on top of a spindle motor using an autocollimator;
• outputting a first bright spot according to the tilt angle from the rotating disc to a monitor through a switch box;
• calculating a tilt angle of an optical pickup head through a host;
• outputting a second bright spot according to the tilt angle from the optical pickup head through the switch box;
• and
• adjusting the first bright spot to coincide with the second bright spot to obtain an optimum tilt angle of the optical drive.

A method for adjusting optical disc drives, comprising steps of:

• sensing a tilt angle of a rotating disc located on the top of a spindle motor using an autocollimator;
• outputting a first bright spot according to the tilt angle from the rotating disc to a monitor through a switch box;
• reading a bar code set on an optical pickup head using a reader;
• calculating a tilt angle of the optical pickup head according to the bar code content through a host;
• outputting a second bright spot according to the tilt angle from the optical pickup head through the switch box;
• and
• adjusting the first bright spot to coincide with the second bright spot to obtain an optimum tilt angle of the optical drive.
