ABSTRACT:
An electrostatic recording head with an array of stylus electrodes each of which is provided with a voltage responsive to recording information for scanning video signals by lines in a horizontal direction. The head comprises a thin metal or plastic sheet having predetermined size and thickness. An insulating layer of a predetermined thickness is formed on one side of the thin metal sheet if used as the base material. Lead electrodes are fixed at a given interval on the plastic or the insulating layer and are connected at one end to a drive circuit. Recording electrodes are provided at the other end of said lead electrodes. An insulating layer covers the lead electrodes. Electrostatic recording is effected on a recording element that has been given charges of a polarity opposite to that of the voltage applied in response to the recording information. A control electrode may be employed to eliminate the need for a corona discharge device.
