ABSTRACT:
A method of driving a CD-ROM drive is provided which includes the steps of setting an initial driving speed of a disk to a predetermined N.times. speed, and measuring a length of time t required for generating a correction error signal (CES) of a digital signal processor (DSP) while playing the disk at the predetermined N.times. speed. If it is determined that the measured CES generation time t is smaller than a first reference time t.sub.1, then the disk is played at N.times. speed. If it is determined that the CES generation time t is equal to or greater than the first reference time t.sub.1, and smaller than a second reference time t.sub.2, the disk is played at (N-2).times.speed. If it is determined that the CES generation time t is equal to or greater than an (n-1)th reference time t.sub.n-1 and smaller than an nth reference time t.sub.n after the algorithm is sequentially repeated for all reference times between t.sub.1 and t.sub.n, the disk is played at 2.times. speed. If the CES generation time t is equal to or greater than the nth reference time t.sub.n, the playing of the disk is stopped.
