A method for controlling the rotational speed of a disk player includes first calculating the proportion of time which the disk player is reading data from the disk during a unit time T. Thereafter, the method increases the rotational speed of the disk player if the proportion of time that the disk player spends reading data from the disk is greater than a first threshold during each of m consecutive units of time T, and decreases the rotational speed of the disk player if the proportion of time that the disk player spends reading data from the disk is less than a second threshold during each of n consecutive units of time T.
