ABSTRACT OF THE DISCLOSURE A color video signal recording and/or reproducing apparatus which comprises a circuit for generating a first signal having a field frequency of the color video signal and circuit for generating a second signal which indicates a field interval having a predetermined phase relationship between a horizontal synchronizing signal and a color subcarrier signal. In NTSC signal, the second signal is generated every four field. The first and second signals thus obtained are synthesized to form a composite control signal, and the latter is recorded on a control track of a magnetic tape in the conventional manner. The apparatus further comprises a circuit for comparing the composite control signal reproduced from the tape with a reference control signal. The reference control signal is composed of a third signal having a field frequency and a fourth signal indicating a field interval, in which a phase relationship between a reference horizontal synchronizing signal and a reference color subcarrier signal is equal to said predetermined phase relationship. Thus, in reproducing, a travelling of the magnetic tape is controlled in response to the output of the comparing circuit so that the phase of the composite control signal reproduced from the tape coincides with that of the reference control signal.
