    摘要： According to one embodiment, an information reproduction apparatus includes an information acquisition unit, an error detection unit, and a control unit. The information acquisition unit is configured to irradiate a reference beam, convert the reference beam into a luminance signal, and output the luminance signal when reproducing an information recording Medium. The error detection unit is configured to detect at least one selected from a first error and a second error by extracting a feature extraction quantity from the luminance signal. The first error is of an irradiation angle of the reference beam. The second error is of at least one selected from a temperature and a wavelength of the reference beam. The control unit is configured to control at least one selected from the irradiation angle and the at least one selected from the reproduction temperature and the wavelength of the reference beam using the second error.

    摘要： A method for forming an optical disk including, providing a substrate and an information recording layer on the substrate, and covering the information recording layer with a cover layer having light transmission properties such that a thickness t of the cover layer is determined based on a predetermined function f(n), which depends on a refractive index n of the cover layer, and the function f(n) is, f ⁡ ( n ) = A 1 × n 3 ( n 2 - 1 ) × ( n 2 + A 2 ) ( n 2 + A 3 ) ⁢   ⁢ ( mm ) ,  in which, A1=0.049245, A2=−0.579135, and A3=0.012842, and constants t1 and t2 determine a range of the thickness t of the cover layer so that f(n)−t1
