Abstract

A tension controlled endless tape loop apparatus for use with a high speed video tape duplicator 11 which includes a master tape storage bin 12 for accumulating and storing a length of master video tape in endless loop form for repeated duplication onto a copy tape supplied by the video tape duplicator. Tension controllers, such as vacuum columns 61, 62 provide the master tape at a pre-determined high constant tension to the video tape duplicator 11. Leader tape is spliced to the master tape and used to load the master tape into the master tape storage bin 12 and into the video duplicator 11. An ionizer (fig 8, 75) neutralizes static charges on the master tape and avoids the need to use cleaning tapes. The tension control vacuum columns avoid the need to use a drive tape to pull the master tape and copy tape through the transfer drum of the duplicator.
