An information signal recording apparatus of this invention records on a recording medium a signal which includes a first information signal and a second information signal which differs from the first information signal. It multiplexes the second information signal with a signal which is the first information signal during a first period and which is a constant frequency signal during a second period which differs from the first time period on a frequency basis, and records a resultant information signal on the recording medium. In consequence, the information signal can be recorded on the recording medium in such a way that the time base variations generated in the information signal reproduced from the recording medium can be readily corrected without using a special signal.
