An optical disc drive and the method for adjusting the working speed are disclosed. In the present method, the user decides the highest working speed in advance. Then, in response to an initiation event, the optical disc drive chooses one of the highest working speed and the pre-determined standard working speed as the actual working speed. The actual working speed depends on the determination whether the current working speed is higher than the standard working speed. If the determination is “true”, the optical disc drive uses the standard working speed as the actual working speed. Otherwise, the optical disc drive uses the highest working speed as the actual working speed. Accordingly, for the present optical disc drive, it is easy to adjust the speed and thus the probability of disc shatter and noise level are reduced.
