The invention relates to a compact disc driver, which comprises a main base, a light picker for allowing the front end of the main base to move left and right, a light picker base with a rotary plate for revolving the compact disc, wherein the light picker base is arranged on one side of the main base to allow itself to rotate, and a tray which loads and unloads the compact disc while moving according to the rotation toward inside and outside of the main base, and a loading electric motor which is arranged on the main base and allows the tray to rotate and the end of the light picker base with the rotary plate to ascend or descend. Compared with the amplitude of the main base in the front and back, the amplitude of the main base on the left and right is larger. The compact disc driver of the invention can minimize the length in the front and back and can be applicable to thin and small electronic products such that the loading time and unloading time of the compact disc are correspondingly reduced.
