ABSTRACT:
Devices for the duplication of industrial magnetic tapes, more particularly an electronic device for the fast duplication of magnetic tapes. The device, through a microprocessor, activates selecting circuits to control static memory cards of a memory bank. The selecting circuit generates proceeding signals and selecting signals which single out memory cells of the memory bank for writing and reading. These selecting signals and proceeding signals cause a subdivision of the cards in the memory bank, allotting a part of the memory for reading and another part for writing. The selecting and the proceeding signals are carried out through digital signals. The final digital signals are subjected to a digital-to-analog conversion.
