Abstract

PURPOSE: To obtain plural tapes which do not cause skew distortion at the reproducting in a large number with good efficiency by repeatedly applying the tension change according to the change of the tape tension in the reproducer for each tape thereby performing duplication recording.
CONSTITUTION: A tension simulator 13 creates the tension control signal corresponding to the tape tension changing around the drum from the initial period to the final end point at the time of reproducing one roll of tape with a public video signal reproducer (public VTR unit). This control reference signal is applied to a master machine 10 and is recorded in the track 11a provided in part of the master tape 11. In a slave machine 12-1 is provided a feed side reel motor 25 which is driven according to the output signal obtained by detecting the tension of the tape 15 around a drum 17 with a tension pole 16, outputting the signal corresponding to the moving positions of the pole 16 in a tension detector 23 and comparing the output signal thereof and the control signal from the master machine in a comparator 24.
