A jitter compensation system is applied to a rotary recording medium reproducing apparatus having a reproducing transducer including a reproducing element for reproducing recorded signals from a rotary recording medium, where the rotary recording medium is recorded with an information signal track and also recorded with reference signals for tracking control having predetermined frequencies. The jitter compensation system comprises a separating circuit for separating the reference signals from a signal reproduced by the reproducing transducer, a detecting circuit for frequency-detecting frequencies of the separated reference signals, to produce a jitter compensation signal, and a displacing circuit responsive to the output jitter compensation signal of the detecting circuit, for displacing the reproducing element of the reproducing transducer along a relative scanning direction with respect to the rotary recording medium.
