Abstract
In conventional recorders using electric recording, sooner or later cloudiness of the record carrier occurs and prevents satisfactory recording. The cloudiness is due to the counter-electrode which cannot be manufactured so as to have a perfectly smooth surface. To avoid the said disadvantage the inventive counter-electrode is segmented, each segment being connected to a current-limiting resistor which either is discrete or forms part of the entire counter electrode.
Claims4
A recorder for an associated electrosensitive record carrier having at least one recording electrode and a counter-electrode, each being disposed on the same side of the electro-sensitive record carrier in spaced relation from each other, said counter-electrode comprising a plurality of discrete electrode segments electrically connected in parallel, a plurality of current limiting resistors, each of said segments being connected to one of said current limiting resistors, said recording electrode and said segments being disposed proximate to the electrosensitive paper.
