ABSTRACT:
An information signal reproducing apparatus for tracing a recording medium on which a large number of recording tracks having four kinds of pilot signals with different frequencies from one another recorded successively on each one of the tracks together with information signals are formed with such track pitch as selectively determined from a plurality of track pitches and for respectively detecting the above-mentioned four kinds of pilot signals included in the signals reproduced by the head for reproducing the above-mentioned information signals, thus making a discrimination of the track pitches by outputs of such detections.
