Title: Electrothermorecording head
Inventor: KANAI TSUTOMU
IPC: B41J2/335
Filed: 1988-02-26
Abstract: PURPOSE:To obtain an electrothermorecording head for preventing the deterioration of image quality due to heat accumulation action without decreasing a recording speed by providing a heat release means for a recording electrode. CONSTITUTION:A recording electrode 8 is of tungsten, one of high hardness, high melting-point and low resistance materials, formed on electroinsulative, high-heat- resistant film 10. A rubber-like elastic body 9 is given elasticity so as to allow the recording electrode 8 to follow the unevenness of recording paper. Thus, high-quality recording without any missing bits is assured even when recording paper with somewhat coarse surface is used. A heat release plate 7 is composed of a material with high thermal conductivity and embedded in the rubber-like elastic body 9 in parallel with and close to a train of recording electrodes, with its end bent up to the rear of a plastic heat-support 11. This permits the surface area of the heat release plate to be increased to improve the heat release effect. Further, an electroinsulative film is applied on the surface of the heat release plate 7 so that no shortcircuiting occurs, if the electroconductive layer of the ink ribbon comes into contact with the surface. If continuous recording is performed with this heat release plate 7 mounted, the temperature over 100 deg.C of the rubber-like elastic body part right below the recording electrode is reduced below 50 deg.C.

Abstract: PROBLEM TO BE SOLVED: To enable high-density recording by forming a crystal part of a phase change-type optical recording layer of a phase change-type optical recording medium to have a columnar structure perpendicular to a film face and a smaller heat conductivity at a crystal grain boundary than in a crystal grain. SOLUTION: A phase change-type optical recording medium has a dielectric protecting layer 12, a phase change-type optical recording layer 13, a dielectric protecting layer 14 and a reflecting layer 15 sequentially formed on a polycarbonate substrate 11. The phase change-type optical recording layer 13 contains a phase-changing, optical recording material showing different optical characteristics between a crystal state and an amorphous state consequent to the projection of light. Crystals of the phase-changing, optical recording material in the phase change-type optical recording layer 13 are in a columnar structure growing in a thicknesswise direction. A heat conductivity at a crystal grain boundary is smaller than in crystal grains.  That is, the phase change-type optical recording layer 13 has a structure wherein an organic compound precipitates at the crystal grain boundary of the phase-changing, optical recording material, so that heat conduction in a direction of a film face can be restricted.
