Abstract
A backup electrode arrangement comprises a resilient insulating member across one surface of which are a plurality of electrode segments separated from one another and comprising an electrically resistive material forming a shoe. The electrode shoes provide pressure engagement against an array of recording electrodes in an electrostatic recorder with a recording medium disposed therebetween. The electrical resistivity of the shoes is sufficiently high to protect the recording electrodes from pinhole shorts in the dielectric layer of the recording medium. With the backup electrode positioned directly opposite to the recording electrode array, the charging path impedance is reduced permitting reduction in writing speed and a corresponding increase in overall recording time.
