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 multivibrators or a single multivibrators. The output signals of the two multivibrators are applied to the magnetic head by way of an adding circuit whereas the output signal of the single multivibrator is applied to the magnetic head by way of a logic circuit which reverses the current direction corresponding to the existing data signal. Additionally, an installation for the recovery of binary signals recorded on a magnetic information carrier determines the zero passage of the read-out signal and includes three comparators which compare the read-out signal with predetermined threshold voltages. Only if the output signals of the comparators occur in a predetermined sequence, a received signal is identified as read-out signal.
