Abstract: A bioassay substrate (1) has a circular, planar major surface similar to that of an optical disc, e.g. a CD. The substrate (1) is rotary-driven about a central hole (2). The substrate (1) is provided, on the surface (1a) thereof, with a plurality of wells (8) where hybridization reaction takes place between a probe DNA (nucleotide chain for detection) and a sample DNA (target nucleotide chain). A transparent electrode layer (4) is formed beneath the well (8) in the substrate (1). At the time of hybridization, an external electrode (18) is brought closer from the upper surface (1a) side of the substrate (1) and an AC power is fed between the transparent electrode layer (4) and the external electrode (18), thus applying an AC field to the substrate (1) in the vertical direction.

Abstract: 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.

Abstract: A high-capacity optical disk, such as of 15 GB or greater, is provided. The optical disk comprises an optical disk substrate (3) on which lines of pits (2) corresponding to the record signals are formed; a reflective coating (4) covering the surface of the optical disk substrate (3) where lines of pits ( 2) are formed; and a transparent layer (5) formed on the reflective coating (4) . For reading or reproduction, a laser beam of 350- to 420-nm wavelength is emitted through the transparent layer (5) on the surface to read the signals recorded as lines of pits. The pits are of 80 nm to 250 nm in length and wid th as viewed from the transparent layer side where the laser beam for reproduction is incident. The thickness of the reflective coating is less th an 20 nm, for example, 8 nm or more.
