Abstract: PURPOSE:To obtain a processing method, by which a highly accurate and fine pattern can be easily formed without damaging the characteristics of an organic conductive layer, by a method wherein impurities which make conductivity lower or dissipate are implanted or diffused in desired places of the conductive layer of an electrical element having the organic conductive layer. CONSTITUTION:Impurities 9 which make a conductivity lower or dissipate are implanted or diffused in an organic conductive layer on a substrate 2, that is, desired regions 8 of the accumulated film 5 of monomolecular films consisting of an organic chargetransfer complex, through a desired pattern mask 10 and the low or non-conductive regions 8 are formed. As the impurities to be used, non-conductive materials having a good diffusivity are desirable, such as hydrogen, helium, nitrogen, oxygen, fluorine, neon and argon are useful. According to this method, as there is no need to destruct whatever the organic conductive layer on the substrate in the formation of a pattern, the pattern can be easily formed at an arbitrary region without exerting bad effect whatever except the region to be formed with the pattern. As a result, a highprecision and fine processing is possible.

Abstract: PURPOSE:To improve recording and reproducing characteristics, corrosion resistance and durability by using a protective layer which contains mixed monomolecular film of a fluorine-contg. org. compd. and org. compd. without contg. fluorine or the cumulative film thereof. CONSTITUTION:A magnetic material layer and the org. protective layer are provided on a substrate. The mixed monomolecular film of the fluorine-contg. org. compd. and the org. compd. without contg. fluorine or the cumulative film thereof is incorporated into the protective layer. Fe, alloy essentially consisting of Co-Ni or the oxide, nitride thereof, etc., are usable for the material of the magnetic material layer 2; the Co-Cr alloy which has a high-density recording characteristic and excellent corrosion resistance or the ferromagnetic film essentially consisting of the Co-Cr alloy is more preferable. The high formation temp. of the Co-Cr alloy film is preferable to improve the coercive force of the Co-Cr alloy film which is the magnetic layer. A polyamide, polyimide resin and more particularly arom. polyimide resin having heat resistance are preferred for the high-polymer substrate. The recording medium having the excellent runnability, durability and environmental resistance is thus obtd.

Abstract: PURPOSE:To enable ternary recording to be performed with two kinds of dots on a single disk, by a method wherein an optical recording medium having a recording layer comprising a monomolecular film or built-up film of a diacetylene derivative having both a hydrophilic moiety and a hydrophobic moiety and a pyrylium dye is irradiated with UV rays, and is then irradiated with light while controlling the light exposure according to recording information. CONSTITUTION:When being irradiated with UV rays, a DA compound in a recording layer is polymerized to be a polydiacetylene derivative, and the color of the layer is changed to blue or a dark color. Recording information is converted into an optical signal by a semiconductor laser through a controlling circuit. The optical signal is led through an optical system to a predetermined position of an optical recording medium, thereby forming an image. The light exposures at image-forming points 3a, 3b are controlled respectively to a quantity Q1 sufficient to heat the polydiacetylene derivative to or above about 50 deg.C but not to melt the recording layer 2, for color change recording, and a quantity Q2 sufficient to melt the recording layer 2, for pit recording (Q1
