The present invention is directed to a compact disc pickup drive mechanism which eliminates any alignment problems between a drive screw, a drive motor and a supporting frame. The drive mechanism comprises a drive screw having one end rotationally secured to a portion of the supporting frame. The drive screw engages a threaded portion of the pickup carriage so that rotation of the drive screw moves the carriage linearly with respect to the frame. The other end of the drive screw is directly coupled to the shaft of the motor. The shaft of the motor is rotatably supported in the frame. The housing of the motor is not directly connected to the frame so that the drive screw will automatically align with respect to the frame.
