Multiple Speed Tape Duplicating
Tape copies can be made either by the method of direct recording or magnetic printing. So far only direct recording has been successfully applied, ranging from the 1 : 1 nominal-to the 1 : 16 multiple speed mode. Multiple speed tape duplicating is very effective when manufacturing tape records of low nominal tape speed, i.e. 1 7/8 in/s. Design considerations of tape duplicators are reviewed and the efficiency of their practical application discussed.
