An optical disc drive includes a locking part, a transmission-compensation mechanism, and a horizontal adjustment mechanism. The locking part is used to secure the first chucking portion and the second chucking portion of the disc chucker to the chucker seat. Therefore, the disc chucker keeps the optical disc stably. Besides, the transmission-compensation mechanism makes power of the driving motor be precisely transmitted to the optical pickup head. This effectively eliminates error or distortion during reading the optical disc. Furthermore, the horizontal adjustment mechanism is adopted to easily and efficiently regulate the angle between the optical disc and the optical pickup head.
