Patent ID: 7929387

Claim:
An adjusting system for adjusting a tilt of an optical pickup head, comprising: a collimator for receiving reflected light beams from the optical pickup head and generating images from the reflected light beams; a processing device for processing the images and generates an adjust signal; and a controller for receiving the adjust signal and adjusting a position of the optical pickup head based on the adjust signal; a driver for turning an adjustable screw fixing the optical pickup head; and a motor for being controlled by the controller to rotate the driver; wherein the adjust signal is generated by: the processing device recording initial coordinates of a first static spot, a second static spot, and a dynamic spot in an image generated from three reflected light beams from the optical pickup head; the controller controlling the motor to rotate the driver to turn the adjustable screw a predetermined calibrated rotation angle θ 1 ; the processing device recording current coordinates of the first static spot, the second static spot, and the dynamic spot in another image generated from three reflected light beams from the optical pickup head; and the processing device generating the adjust angle according to the initial coordinates, the predetermined calibrated rotation angle, and the current coordinates.
