VIDEO SIGNAL RECORDING AND/OR REPRODUCING APPARATUS ABSTRACT OF THE DISCLOSURE In a video signal recording and/or reproducing apparatus including four magnetic heads mounted on a rotary drum for forming four parallel recording tracks in a repeating sequence on a recording medium with each track having an azimuth gap angle different from the azimuth gap angles of the next adjacent tracks; pilot signals having different frequencies are recorded in a superimposed manner upon the information signals recorded by the four magnetic heads, respectively, and, upon reproducing, tracking control is effected so as to ensure that the magnetic heads which recorded the pilot signals with different respective frequenci? ?d to reproduce the signals recorded in the respective recording tracks so that a period of a timing signal, for example, a horizontal synchronizing signal, contained in the reproduced signal will not be disturbed upon switching from one to another of the magnetic heads in the reproducing mode.
