ABSTRACT:
An apparatus for reproducing information signals recorded with a plurality of pilot signals having different frequencies on a tape-like recording medium, in which a tracking error signal is formed by using the pilot signals reproduced by the head for reproducing the information signals, and pulse signals generated in correspondence to the moving action of the recording medium during a period of variation in level of the tracking error signals are counted to discriminate whether the recording speed of the information signals and the moving speed of the recording medium are coincident or not.
