Abstract
An optical recording and reproducing apparatus includes a deck, a spindle motor supported by the deck, a turntable combined with the shaft of the spindle motor, and a corrector for moving the spindle motor horizontally with respect to the surface of the deck in order to adjust the position of the turntable. Accordingly, the tracking error is easily corrected, thereby improving the performance of the apparatus.
