ABSTRACT:
The recorded content of a magnetic card is transferred directly to a magnetic tape simply by bringing the magnetic card into contact with the magnetic tape and applying a magnetic field to the contacting area with the aid of a copy magnet or a magnetic printing head energized by D. C. current or A. C. current, on the condition that the coercive force of magnetic material on the card is larger than that on the tape, and a reproducing head mounted along the path of the tape reproduces the transferred content. Thus, the recorded content of a magnetic card can be reproduced many times just by engaging the card in the device once.
