PURPOSE: An optical disc drive is provided to fundamentally prevent a guide feed from moving in front of an end of a lead screw. CONSTITUTION: A lead screw(23) is rotated by a step motor. A guide feed(22) is in connection with the lead screw. The guide feed horizontally moves an optical pickup to an inner circumference and an outer circumference of an optical disc. A slip groove(230) stops movement of the guide feed in an end of the lead screw. A mold tension unit contacts the body of the step motor.
