<p>PURPOSE:To completely prevent the reproducing image from being bent in shape and color slurring by winding a magnet tape around a rotary drum in such a winding method of overlapping at a specified angle. CONSTITUTION:The rotary drum 4 with a pair of rotary video heads 2a and 2b and a pair of rotary audio heads 3a and 3b, wound with a magnetic tape 1 is rotated in the direction of an arrow A. In this case, the winding of the magnetic tape 1 to the rotary drum 4 is performed in the overlapping winding at the angle corresponding to a tape length of approximately 0.5 times as long as a vibratory wavelength of magnetic tape vibration generated by shocking at the time of bumping into and separating from the magnetic tape 1 against a rotational angle for forming one field image of the rotary heads 2a, 2b, 3a and 3b. By this method, the vibration of the magnetic tape 1 is attenuated, and even when a compatible reproducing is performed between different VTRs in the number of rotary heads, the bend and color slurring of the reproducing image is scarcely generated so that the excellent reproducing image quality can be obtained.</p> |
