摘要： PURPOSE:To enable optical reading at high speed with high precision by recording information on a recording layer containing a polydiacetylene derivative and a squarilium dye with infrared rays specified in wavelength, and reading the information with a visible light specified in wavelength. CONSTITUTION:The optical recording medium 1 is provided with the recording layer containing the diacetylene derivative (DA) and the squarilium dye. Ultraviolet rays are projected on the whole surface of the recording layer to polymerize the DA compound and to change its color to blue. The optical recording is executed by converting the input information through a control circuit 3 into infrared ray signals of 800-900nm wavelength and forming images at the prescribed positions of the medium 1, and changing the blue of the DA compound to red by heating of said layer. The record is read by focusing the reading light of 500-750nm wavelength emitted from a semiconductor laser device or a light emitting diode 10 on the recording part of the medium 1, converting the reflected light through a photodetector 12 into electric signals, and sending them to an output circuit 11.

摘要： 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

For example, 1pts.wt. of a crystalline fine powder of the diacetylene derivative compound represented by general formula C12H25-CidenticalCidenticalC-C8H16-COOH and 1pts.wt. of the pyrylium dye are added to 4pts.wt. of methylene chloride and the resulting mixture is sufficiently stirred and applied to a substrate to form the optical recording medium 1. This optical recording medium 1 is uniformly and sufficiently irradiated with ultraviolet rays with a wavelength of 254nm to polymerize the DA compound in the recording layer to convert the recording layer to a blue film and, thereafter, when the surface of the blue optical recording medium is irradiated with laser beam of 830nm, the irradiated part is discolored to red to perform a desired recording.

摘要： PURPOSE:To provide an optical recording medium capable of high-speed recording with high density and high sensitivity, by providing a recording layer which comprises a layer consisting of a monomolecular film or built-up film of a diacethylene derivative compound (DA compound) having a hydrophilic part and a hydrophobic part and a layer comprising a croconic methine dye in a laminated form. CONSTITUTION:A layer 4 comprising a croconic methine bye is provided on a base 1, and a layer 3 consisting of a monomolecular film or built-up film of a DA compound is provided thereon to form a recording layer 2. Since the layer 3 of the monomolecular film or built-up film of the DA compound has a high density and a high degree of orderliness, it shows extremely uniform light absorption at all parts thereof. Accordingly, by constituting the recording layer 2 of such a film, a recording medium can be obtained which is capable of optical recording and thermal recording according to the functions of the DA compound and the croconic methine dye, and has the function for high- density high-resolution recording.
