PURPOSE:To make the titled recording head adaptable to a hard recording body based on a metal drum without using a charge corotron, by forming the main electrode and the control electrode of an electrostatic recording head on a thin metal plate. CONSTITUTION:An electrostatic recording head 10 is constituted from a thin base metal plate 1 comprising phosophorus bronze, an insulating layer 2 comprising polyimide resin for covering the entire region of the single surface thereof, an integrated circuit 2 for a stylus drive circuit fixed on said insulating layer 2, lead electrodes 5 connected to said circuit 2 at predetermined intervals and provided with recording electrodes 4 at the leading end parts thereof, control electrodes 7 opposed to the recording electrodes 4 and respective insulating layers 6, 8. In this case, because the leading end part of the head 10 is attached to a hard recording body 9 so as to be contacted therewith by a proper elastic force and the metal plate 1 is flexibly contacted with said recording body 9 as a leaf spring, damage is not generated. In addition, because the control electrodes are provided, it is unnecessary to perform charging prior to recording and a charge corotron is eliminated. |
