摘要： The present invention relates to a production process and a oduction apparatus for the optical information recording media comprising a material thin film 1 which exhibits a reversible range of the optical characteristics by the irradiation of an hergy beam such as a laser beam 4 from the laser light source 7 in the substrate 2. By having a means to dropping the emission trength instantly to the virtual zero level after having the mission for a specified time (shutoff circuit portion 10) in ponducting the initial crystallization process, both a large radiation power and a short irradiation time can be achieved to reduce the various thermal damages. Since the method does not aste electric energy, the time to complete recharging of the lectric energy for the next discharge emission can be shortened. Further, by having a means to maintain a great difference etween the applied voltage and the charging voltage (storage circuit 8 and trigger circuit 9), recharging time can be further hortened to facilitate the treatment speed of the initializing process. Further, in the production process of optical information recording materials with single side structure, in articular, by applying an annealing process in combination with formation process of the resin protection layer or a recording hin 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： There are provided an optical disk and a manufacturing method thereof which can increase its recording capacity, e.g. to 15 GB or higher. This optical disk may comprises an optical disk substrate 3 in which successive pits corresponding to a recording signal are formed, a reflection film 4 formed in this optical disk substrate 3 on its surface that successive pits 2 are formed and a light transmissive layer 5 formed on this reflection film 4. When a recorded signal is read out, i.e. reproduced from the optical disk, a signal recorded as successive pits is read out by irradiating of short-wavelength laser light having a wavelength of 350 nm to 420 nm from the side of the light transmissive layer 5 formed on the surface of the optical disk. Moreover, in this optical disk, when the successive pits are observed from the side of the light transmissive layer irradiated by reproducing laser light, the successive pits contain pits having length and width ranging from 80 nm to 250 nm, and the reflection film has the film thickness selected to be 20 nm or less, e.g. greater than 8 nm.

摘要： The invention concerns a medium comprising a two-layered stack consisting of an inorganic layer (30) and a semi-reflecting layer (32). The inorganic layer (30) is adapted to be deformed under the effect of a light radiation (34) directed through the semi-reflecting layer, thereby reducing the reflection coefficient of the stack. The invention is useful for irreversibly recording data, for example on discs.
