PURPOSE:To erase and rerecord video at the same time as reproducing, by attaching reproducing, erasing, and recording heads continuously at both ends of a head bar. CONSTITUTION:When a main power source is turned on and respective switches S1, S2, and S3 of a reproducing circuit, an erasing circuit, and a recording circuit are turned on for the purpose of reproducing, erasing, and recording video in the same time zone during the running of a single tape 16, the tape 16 where video is already recorded starts running on outside circumferential faces of cylinders 11 and 12, and simultaneously, a rotary head 5 starts rotating in a certain speed. First, reproducing heads 2 and 2' scan a reproducing band 6 of a magnetic face 17 of the tape 16 to reproduce the already recorded video onto a television; and after this scanning of reproducing heads 2 and 2', erasing heads 3 and 3' erase video on said reproducing band 6 widely, and recording heads 4 and 4' which are turned immediately after this erasing record successively the televised video. |
