Abstract
PURPOSE: To realize the high-speed and high-quality duplication of the video tape by setting the feed speed of both the master and slave tapes to α-times as high as the standard system and then securing the simultaneous reproduction and recording for the signals of α-pieces of adjacent tracks.
CONSTITUTION: Feed speed vt' of tape 1 is set to α-times as high as feed speed vt of the standard system, and also the number of units is selected for video head 4 to α-times as much as those of the standard system. Then heads 4 are distributed on the circumference of disc 3 with the fixed angle pitch, and the winding angle is set for tape 1 on cylinder 2 in such way that the adjacent heads may deliver the reproduction signals from the video tracks of the same number at one time. Acordingly, if these video signals reproduced at one time are recorded to other video tapes by means of the same recorder as that used at the reproducing time, the duplication of the tapes becomes possible in the speed of α-times as high as the standard system.
