Abstract
The invention concerns a method of recording information on an electrosensitive record carrier, preferably a record carrier covered with a metallic or metalliferous layer, by means of a print head movable relatively parallel to the surface of the record carrier and comprising at least one print electrode controllable by print pulses, and a control circuit for the timely generation of the print pulses from digital or analog signals received in such a manner that the duration and amplitude of each print current pulse are chosen so that the print process triggered by the individual print pulse is completed by the time the print pulse stops.
