摘要： The optically transparent protective sheet is made of cured product of a radiation curable paint in the form of a sheet. The optical recording medium includes an optical recording layer formed on at least one surface of a substrate, an adhesive layer formed on the optical recording layer, and an optically transparent protective layer formed on the adhesive layer, wherein the optically transparent protective layer is formed by adhering the optically transparent protective sheet to the optical recording medium, with intervening the adhesive layer therebetween. Such an optically transparent protective sheet is superior optical characteristics, such as thickness accuracy, a birefringence, and light transmittance, and does not have a residual solvent. The optical recording medium using such an optically transparent protective sheet is superior in the optical characteristics, and is capable of increased capacity. The optical recording medium can be produced with a good productivity at low cost by using the optically transparent protective sheet.

摘要： PURPOSE: To prevent possibly the warp and meandering of a base with a comparatively simple constitution and to attain stable information processing over a long term, by clipping the outer circumference on one side on which an information forming layer is formed and the outer circumference of a reinforcing base opposing to the former base with an elastic spacer and connecting the bases in facing the information forming layer to inside.
CONSTITUTION: The elastic spacer 16 is clipped and bonded between the outer circumference of the base 11 and an elastic spacer bonding quide groove 17 of a reinforcing base 13, the inside thick part 14 of the reinforming base 13 is bonded to the side of the information forming layer 12 of the base 11, and the base 11 and the reinforcing base 13 are bonded incorporatedly so that the information forming layer 12 is placed inside and an internal space 19 is formed. Thus, the internal space 19 is formed between the information forming layer 12 and the reinforcing base 13 by the height of the inside tnick part 14, then no special inner space is required and the loading/unloading is attained easily. Further, the difference in size between the base 11 and the reinforcing base 13 caused by the change in temperature and humidity is absorbed by the elastic spacer 16, allowing to prevent warp and meandering of the base 11.

摘要： PROBLEM TO BE SOLVED: To surely strip only a stripping sheet without stripping a protection sheet from a resin film of a cover sheet when a stripping sheet is stripped from a cover sheet before the protection sheet. SOLUTION: When adhesive force for sticking a stripping sheet 36 to an adhesive film 28 of a cover sheet 24 is assumed to AP 1 , and adhesive force for sticking a protection sheet 38 to a resin film 26 of the cover sheet 24 is assumed to AP 2 , a cover sheet package 34 is constituted so that the following equation is satisfied; AP 1 ≤ AP 2 . Thereby, when stripping force is applied to one end part of the stripping sheet 36, only the stripping sheet 36 stuck to the adhesive film 28 of the cover sheet 24 is smoothly stripped toward the other end part from the one end part, without stripping the protection sheet 38 from the resin film 26 of the cover sheet 24.
