    摘要： The present invention relates to a production process and a production apparatus for the optical information recording media 3 comprising a material thin film 1 which exhibits a reversible change of the optical characteristics by the irradiation of an energy beam such as a laser beam 4 from the laser light source 7 on the substrate 2. By having a means to dropping the emission strength instantly to the virtual zero level after having the emission for a specified time (shutoff circuit portion 10) in conducting the initial crystallization process, both a large irradiation power and a short irradiation time can be achieved to reduce the various thermal damages. Since the method does not waste electric energy, the time to complete recharging of the electric energy for the next discharge emission can be shortened. Further, by having a means to maintain a great difference between the applied voltage and the charging voltage (storage circuit 8 and trigger circuit 9), recharging time can be further shortened to facilitate the treatment speed of the initializing process. Further, in the production process of optical information recording materials with single side structure, in particular, by applying an annealing process in combination with a formation process of the resin protection layer or a recording thin fil initialization process, the warp or distortion of media caused by the contraction of the ultraviolet ray curing resin layer or the recording thin film layer can be reduced or corrected to realize an optical information recording medium having excellent servo characteristics. Further, by having at least one of two media to be affixed with a transmissivity of an ultraviolet ray of 3 % or more as a method to comprise an optical information recording medium with double sides structure not liable to have a warp or distortion, an ultraviolet ray curing resin can be used as an adhesive, resulting in simplifing the production process.

    摘要： In a method and an apparatus initializing an optical recording medium by irradiating a flash light, walls are formed on a holder for holding the optical recording medium so as to adjoin an inner edge and an outer edge of the optical recording medium. When a flash light irradiates, a part of incident light which obliquely enters into an inner and an outer periphery regions of the optical recording medium is shaded by the walls. A quantity of the incident light incident on a unit area in each of the inner and outer periphery regions is less than that in a recording region between the inner and outer periphery regions. When temperature in the recording region reaches to an initializing temperature, the temperature in each of the inner and outer periphery regions is lower than the initializing temperature, so that neither cracks nor corrugations occur in a recording layer in the inner and outer regions.

    摘要： In a record medium wherein information is recorded and/or erased by changing the optical state thermally by the irradiation with a laser beam or the like, a protection layer made from a material having a larger thermal conductivity than adjacent protection layers is used to decrease the temperature difference between the center and edges of a record mark on recording and/or erasing with a laser beam. By using the material having a larger thermal conductivity, the heat due to the irradiation with a laser beam or the like is diffused not only to the periphery of the substrate, but also to the plane of the substrate surely. Therefore, the temperature difference between the center and the edges in a mark on irradiation with the laser beam is decreased, and the recording/erasing characteristics and the power margin for erasing can be improved.
