概要

• 論文の詳細を見る

• A 10-layer recordable optical disc with an inorganic recording material, Bi–Ge–O, was fabricated and the recording characteristics were measured using a Blu-ray Disc-based apparatus with a wavelength of 405 nm and a numerical aperture of 0.85. Practical signal quality was obtained from all the layers at densities of 25 and 32 Gbyte per layer. A 16-layer recordable optical disc was also fabricated and measured. Practical signal quality was also obtained from both the 1st layer and the 16th layer.
