ABSTRACT:
An information signal recording and reproducing system for recording and reproducing an information signal on and from a recording medium comprises a modulation circuit for modulating the information signal to form a modulated signal involving a number of pulses, a first frequency divider triggered responsive to a leading edge of the pulses in the modulated signal to produce a first frequency-divided signal having a frequency substantially lower than that of the modulated signal, a second frequency divider triggered responsive to a trailing edge of the pulses in the modulated signal to produce a second frequency-divided signal having a frequency substantially lower than that of the modulated signal, a recording device for recording the first and second frequency-divided signals on the recording medium, a reproducing device for detecting the first and second frequency-divided signals recorded on the recording medium to produce a first reproduced frequency-divided signal and a second reproduced frequency-divided signal, a synthesizing circuit supplied with the first and second reproduced frequency-divided signals to produce a synthetic modulated signal corresponding to the modulated signal by performing an exclusive-or operation of the first and second frequency-divided signals, and a demodulating circuit supplied with the synthetic modulated signal to produce a reproduced information signal.
