Abstract
The present invention provides a recording medium comprising a recording layer on an electrode substrate and one or a plural number of fine lone electrode made of an electroconductive material provided on said recording layer.
Claims18
A recording medium comprising a recording layer on an electrode substrate, said recording layer comprising an organic compound, and a plurality of fine lone electrodes comprising an electroconductive material disposed systematically on said recording layer wherein a voltage can be applied on the recording medium through said fine lone electrodes on said recording layer.
A method for preparing a medium comprising forming a recording layer on an electrode substrate and forming a plurality of fine lone electrodes comprising an electroconductive material by the lithographic method.
A method for preparing a recording medium comprising the steps of:
- forming a first electrode layer by depositing an electroconductive material on a substrate;
- forming a recording layer comprising a monomolecular film or built-up monomolecular films of an organic compound according to the Langmuir-Blodgett method on said electrode layer;
- forming a second electrode layer by forming an electroconductive material on said recording layer;
- and
- forming a plurality of fine lone electrodes from said second layer by coating a resist material on said electrode layer, and exposing and developing said resist material.
