Information signal reproducing apparatus capable of determining a track pitch of a record bearing medium using a tracking error signal and a signal indicative of the moving speed of the medium

Claim 1

An information signal reproducing apparatus for reproducing information signals recorded on a tape-shaped recording medium with a plurality of pilot signals of different frequencies, comprising: (a) a reproducing head arranged to trace said recording medium for reproducing the information signals and the pilot signals; (b) moving means for moving said recording medium in a longitudinal direction thereof; (c) forming means for forming a tracking error signal by using the pilot signals reproduced by said reproducing head; (d) first generating means for generating a pulse signal having a frequency corresponding to a moving speed of the recording medium by detecting a recording medium moving action of said moving means; (e) second generating means for generating a cyclic signal having a cycle corresponding to a cycle of the track error signal; (f) counting means for counting the pulse signal generated by said first generating means for a period determined according to the cycle of said cyclic signal; and (g) discriminating means for discriminating whether or not a recording medium moving speed of said moving means is coincident with a recording speed of the information signals recorded on said recording medium, said discriminating means including a first discriminating means for discriminating whether or not a counted output of said counting means is within a predetermined range of values at every cycle of said cyclic signal.
