The duplicator is made up of a continuous feed magazine of blank cassettes; a changer which moves the cassettes from the magazine to the tape transport and, after duplication, away from the tape transport; and the tape transport itself, which winds the tape within the two cassettes while playing back the master tape and recording a duplicate.
