摘要： An optical information recording medium includes a transparent substrate, a first protection film, a recording film, a second protection film, a dielectric film, and a dielectric reflective film. The first protection film is formed on the transparent substrate. The recording film is formed on the first protection film to record and erase information by causing a reversible phase change between a crystalline state and an amorphous state upon being irradiated with a laser beam, and reproduce recorded information by detecting a change in optical nature accompanying the phase change in the recording film. The second protection film is formed on the recording film to protect the recording film together with the first protection film. The dielectric film is formed on the second protection film and has a refractive index lower than a refractive index of the transparent substrate. The dielectric reflective film is formed on the dielectric film and has a refractive index higher than the refractive index of the transparent substrate.

摘要： The optical data recording media is provided on a substrate with a recording layer changing its optical characteristic dependent upon difference in the heat history, or processes of temperature elevation due to laser beam irradiation and the following cooling. The media is composed of layered structure not only varying its own reflectance or transmittance as an integrated media, but also changing the optical phase of the reflected light or transmitted light, when the optical characteristic of the recording layer is changed. In the method of recording, erasing and reproducing data using this optical data recording media, when the variations of the reflectance is to be detected, recording and erasing are effected after temporarily setting the recording layer in a state having a higher reflectance. On the other hand, when the variations of the transmittance is to be detected, recording and erasing are effected after temporarily setting the recording layer in a state having a higher transmittance. The substrate has such guide grooves that the width of either the convex portion between the guide grooves or the concave portion of the guide grooves is smaller than the diameter of the laser beam spot for reproduction.

摘要： An optical disc has a read-only system lead-in area and a recordable data area. Disc boundary information representing a boundary in a radial direction of an area on which capability of recording at a predetermined recording speed is guaranteed is recorded on the system lead-in area while being related to each tuple speed. An optical disc device, upon user's instruction of tuple-speed recording, compares the boundary information related to the instructed tuple speed with a present recording position, performs recording at the instructed tuple speed if the present recording position is on the outside of the boundary, and performs recording at a tuple speed lower than the instructed tuple speed if the present recording position is on the inside of the boundary.
