Method and arrangement for controlling a row of recording electrodes for recording information on an electrosensitive record carrier

摘要

1. Method of controlling the print electrodes of a print head comprising several electrodes and serving to record information on an electrosensitive record carrier, said print head moving substantially parallel to the surface of the record carrier, characterized in that upon being activated by a print data pulse, an electrode receives a print current pulse consisting of a firing pulse of short duration and high amplitude and a self-extinguishing burn-out pulse of low amplitude and substantially longer duration than the firing pulse, and that upon activation of several electrodes, a time-staggered print current pulse is applied to each electrode such that the firing pulse of a print current pulse is overlapped in time only by the respective burn-out pulse of preceding print current pulses.
