摘要： The invention provides an optical recording medium having excellent weatherability and a process for producing the same. The optical recording medium is provided with an organic dye layer, a reflecting layer and a protective layer in this order on a light-transmittable substrate. The organic dye layer contains an organic solvent in an amount of 2% to 15% by weight based on the organic dye. A solution, prepared by dissolving an organic dye in an organic solvent, is applied onto the light-transmittable substrate by a spin coating method to form an organic dye layer. A reflecting layer is formed on the organic dye layer without performing a drying treatment of the organic solvent in the organic dye layer, followed by forming the protective layer on the reflecting layer. The result is an optical recording medium containing an organic solvent in an organic dye layer in an amount of 2% to 15% by weight based on an organic dye.

摘要： A multi-level optical recording medium according to the present invention is a multi-level optical recording medium (1) which is capable of recording record data according to multi-level recording that defines light reflection ratios of recording portions (12) into multiple levels by switching the irradiation amount of a recording laser beam between multiple levels, wherein light reflection ratio information enabling identification of a light reflection ratio dynamic range within which respective light reflection ratios of the recording portions (12) should be included is readably recorded. Due to this construction, when record data are recorded, it is only required to record the record data such that the respective light reflection ratios of the recording portions (12) are included within the light reflection ratio dynamic range identified from the light reflection ratio information, and it is unnecessary to perform the operation of checking the characteristics of the multi-level optical recording medium (1) prior to recording the record data. Therefore, it is possible to record the record data promptly and easily without wastefully using a data-recording area.

摘要： On a recording layer (12) of a disc-shaped optical recording medium (10), a plurality of virtual recording cells (40) are assumed contiguously in a spiral or concentric fashion in a groove (16). The irradiation time of the laser beam is modulated in five stages or more for each of the virtual recording cells (40) in response to information to be recorded, thereby forming recording marks (48A to 48G) of different sizes in five stages or more. The optical reflectivity of the virtual recording cell (40) is modulated in multi-stages to thereby vary the reflection level of a reading laser beam for reading operations in five stages or more. The length of the virtual recording cells (40) in the rotational direction of the disc is set to be equal to that of an arc having the same center angle with respect to the center of the disc.
