Abstract
A device for recording an image includes a recording surface and a write head positioned next to the recording surface. The write head has at least one microtunnel, with each microtunnel having an anode placed near the recording surface and a cathode located further away from the recording surface than the anode, so as to permit generation of a gas plasma between the anode and the cathode. A voltage source varies the voltage of the anode so as to permit recording of the image on the recording surface. In another embodiment, an additional anode is located near the cathode further away from the recording surface than the first anode.
