APPARATUS AND METHOD FOR RECORDING AND REPRODUCING A VIDEO SIGNAL IN SUCCESSIVE RECORD TRACKS ON A RECORD SHEET WITHOUT GUARD BANDS BETWEEN ADJACENT TRACKS

摘要

Video signals are recorded in successive record tracks on a record sheet without guard bands or spaces between adjacent tracks so as to enhance the utilization of the record sheet, and 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 at right angles to the length of the tracks and further 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, for example, as by a reproducing magnetic head having a gap width substantially greater than the pitch of the successive tracks in which the signals are magnetically recorded, so as to enhance the resolution and S/N ratio of the reproduced signals and further to avoid the necessity of a servo tracking arrangement.
