    Abstract: A DIELECTRIC PART 4 COMPRISING A NITRIDE LAYER 7 AND AN OXIDE 8, LAID ONE UPON THE OTHER, IS FORMED ON A DATQA-RECORDING LAYER 3. AT LIGHT-TRANSMITTING LAYER 5 IS BONED WITH ADHESIVE TO THE DIELELCTRIC PART 4. SINCE THE DIELECTRIC PART 4 IS INTERPOSED BETWEEN THE DATA-RECORDING LAYER 3 AND THE LIGHT TRANSMITTING LAYER 5, THE ORGANIC MATERIAL OF THE DATA-RECORDING LAYER 3 DOES NOT DIFFUSE INTO THE ADHESIVE THAT BONDS THE LIGHT EMITTING LAYER TO THE DIELECTRIC LAYER 4. ADDITIONALLY, THE DATA-RECODING LAYER 3 IS NOT DTERIORATED DUE TO OXYGEN PLASMA GENERATED DURING THE PROCESS OF FORMING THE OXIDE LAYER 8 BECAUSE THE OXIDE LAYER 8 IS PROVIDED ON THE NITRIDE LAYER. SINCE THE NITIRDE LAYER 7 HAS A THICKNESS OF 10 NM OR LESS, IT DOES NOT INFLUENCE OPTICAL ENHANCEMENT EFFECT.

    Abstract: A laser scanning apparatus raster scans an input laser beam ( 0) by using an acousto-optic deflector arrangement. The laser beam is horizontally scanned by a pair of acousto-optic deflectors (13a, 13b). Thus, a laser scanning apparatus can be realised which is low in noise, of excellent durability, small in size, light in weight and which can display a picture of high quality at high speed.

    Abstract: A rewritable optical information recording medium including a recording layer composed of an organic dye film is provided, in which recording and erasing information can be performed reversibly by laser light irradiation. A rewritable optical information recording medium including at least one organic dye film which is substantially made of only at least one kind of organic dye compounds as a recording film is provided. The recording and erasure of information are performed by a reversible physical change of the organic dye film substance caused by laser light irradiation. Specifically, data recording is performed by a physical change locally caused by the irradiation of recording laser light, data reproduction is performed by detecting change in intensity of returned light of reproducing laser light having less power than the recording laser light, and data erasure is performed by applying at least once continuous light or pulse light having laser power more than the reproducing laser light and less than the recording laser light. The physical change is a change in shape.
