Abstract

See full text

A recorder/reproducer having two capstans which engage a magnetic tape passing from a delivering coil holder to a receiving coil holder of a cartridge is disclosed. At the time of loading the tape, the capstans are shifted from a rest position along a path toward the scanner which has an upper, rotatable drum. In this working position, the capstans are in close proximity to the scanner which eliminates the great lengths of the tape which generate undesired longitudinal vibrations in the tape.
