ABSTRACT:
In an electrostatic stylus recorder, a DC biased RF field is produced between the writing styli and the dielectric recording element. The DC bias prevents charged gas ions from bombarding and thereby abrading the dielectric recording element during electrical discharge between the styli and the recording element.
