ABSTRACT OF THE DISCLOSURE A servo system for controlling a motor rotation to rotate a disc having thereon information modulated in run length limited code is disclosed, which includes a circuit for counting the number of pulses of the maximum transition interval in the information reproduced from the disc, a loop for controlling the motor rotation at a constant linear velocity in response to the output of the counting circuit, a phase comparator for digitally phase-comparing a phase information signal of the signals reproduced from the disc with a reference signal having a frequency N times that of the phase information signal at every N times and a loop for controlling the phase of the motor through the output of the phase comparator.
