Abstract: PURPOSE: To avoid degradation of the picture quality dependent upon tracking error and so on for reproducing, by recording plural sets of simultaneous signals in the time division direction in the time series order.  
     CONSTITUTION: Magnetic tape 15 is caused to run in the longitudinal direction by 9.5cm/sec and so on, and A and B in the figure are set to regions corresponding to the vertical fly-back time and the horizontal fly-back time respectively, and control is so performed that no signal may be recorded on these regions. As a result, respective 50 line signals of the 1stWthe 50th line signals, the 51stWthe 100th line signals,... and the 201stWthe 50th line signals are recorded successively in the width direction of the tape on tracks different from one another at the interval of region B in respect to one-field components B. Consequently, even if crosstalk is caused by tracking error and so on for reproducing, correlation between two signals of line difference 1 is taken simply, and therefore, degradation of resolution in the vertical direction is lowered, and picture quality degradation is avoided practically.
