Abstract
Video signals are recorded in successive record tracks on a record medium without guard bands or spaces between adjacent tracks, thereby enhancing the utilization of the record medium. Interference between the signals recorded in adjacent tracks is avoided during reproduction thereof by recording such video signals in adjacent tracks with their respective synchronizing signals aligned in the direction substantially at right angles to the length of the tracks and with carrier components of the signals recorded in the adjacent tracks being of the same frequency and having the same phase relation to the effective scanning direction during recording. During reproduction of the signals thus recorded, non-interfering signals recorded in two or more adjacent tracks are simultaneously reproduced by a reproducing magnetic head without the necessity of a servo tracking arrangement to align the scanning paths of the magnetic reproducing head relative to the record tracks.
