ABSTRACT:
The disclosed information signal reproducing apparatus reproduces information signals from a recording medium with a number or tracks. Four pilots signals having different frequencies from one another are recorded successively on the tracks along with information signals. A reproducing element only traces alternate ones of the recording tracks. A generator produces a signal having a prescribed frequency. A signal processing circuit forms a tracking control signal for a reproducing element from the prescribed frequency signal obtained from the generator and the pilot signals reproducing by the reproducing element, and a control circuit controls the tracking of the reproducing element based on the tracking control signal.
