Information signal recording/reproducing apparatus with time base correction facility
 An information signal recording/reproducing apparatus includes a recording apparatus and a reproducing apparatus. The recording apparatus is arranged to record on a recording medium an information signal after angle-modulating the signal in such a way as to cause a signal corresponding to a timewise portion of the angle-modulated information signal to be in a given relation to a reference signal. The reproducing apparatus is arranged to angle-demodulate the angle-modulated information signal when it is reproduced from the recording medium, and to perform time base correction on the basis of the signal part of the angle-modulated information signal. Time base variations occurring during the reproduction can be accurately carried out by the arrangement without having any special signal added to the information signal during recording.
