Abstract
In recording periodic information signals, such as, the chrominance signal components of video signals, having first or field intervals and second or line intervals which are recorded in respective areas or increments of successive parallel tracks on a record medium with the ends of the margins between the areas in which the second or line intervals are recorded in each of the tracks being aligned in the direction transverse to the lengths of the tracks, with the adjacent ends of such margins in the next adjacent tracks; interference or cross-talk between signals recorded in adjacent tracks is reduced or eliminated during reproduction by recording the information signals with different first and second carriers in the adjacent tracks, respectively. Such first and second carriers for signals recorded in adjacent tracks may be distinguished from each other by their respective frequency and/or polarity characteristics so that, upon reproduction of the signals recorded in a particular track, the cross-talk signals from adjacent tracks can be conveniently suppressed or eliminated, for example, with the aid of a simple comb filter, by reason of the different frequency and/or polarity characteristics of the carriers with which the signals are recorded in that particular track and in the next adjacent tracks, respectively.
