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 present invention relates to a multi-layered disc-shaped information recording medium having a plurality of signal recording layers each carrying information signals. In preparing the recording medium, a first substrate obtained on punching a sheet obtained in turn by having a signal recording pattern transcribed on it from a first stamper and by forming a semi-transparent film on a signal surface is bonded to a second substrate obtained on injection molding a synthetic resin material. The second substrate is prepared by having transcribed to it a signal recording pattern formed on a second stamper provided on an injection molding device. A reflective film is formed on a signal surface having the transcribed second substrate. The first and second substrates are bonded together on their signal recording layers by a transparent adherent layer.

摘要： A bioassay substrate (1) takes a flat-plate shape in which the principal surface similar to that of optical disc such as CD, etc. is circular. At the center of the substrate (1), there is formed a center hole (2) into which a chucking mechanism for rotation and holding is inserted. The substrate (1) is rotationally driven with the center hole (2) being as center. On the substrate (1), there are formed two regions of a recording region (3) and a reaction region (4) which are formed in concentrical form in a radial direction. The recording region (3) is a region where, similarly to the optical disk information recording medium, laser beams are irradiated so that recording/reproduction of information is optically performed. The reaction region (4) is a region serving as the filed of mutual reaction between probe DNA (nucleotide chain for detection) and sample DNA (marked or labeld nucleotide chain), in concrete terms, the field of hybridization reaction.
