Abstract
An installation for recording binary signals on a magnetic information carrier, in which a needle pulse of one polarity is applied to a recording magnetic head during each change of the signals to be recorded from '0' to '1' and a needle pulse of the other polarity is applied during each change from '1' to '0'. The installation includes either two monoflops or a single monoflop. The output signals of the two monoflops are applied to the magnetic head by way of an adding circuit whereas the output signal of the single monoflop is applied to the magnetic head by way of a logic circuit which reverses the current direction corresponding to the existing data signal.
