摘要： An phase-change optical disk comprises a substrate, a first protective layer, a first thermostable layer, a recording layer, a second thermostable layer, a second protective layer, an absorptance control layer, and a heat-diffusing layer which are provided in this order from a side on which a laser beam comes thereinto, wherein a recording layer material has composition ratios which are within a range surrounded by composition points of B3 (Bi3, Ge46, Te51), C3 (Bi4, Ge46, Te50), D3 (Bi5, Ge46, Te49), D5 (Bi10, Ge42, Te48), C5 (Bi10, Ge41, Te49), and B5 (Bi7, Ge41, Te52) on a triangular composition diagram.

摘要： A write-once optical information recording medium is provided that is capable of realizing a high transfer rate and a method of recording and reproducing information on and from the optical information recording medium. The optical information recording medium is constructed by stacking a reflective layer 12, a first dielectric layer 13, a recording layer 14, a write-protect layer 15, a second dielectric layer 16 and a transparent cover layer 17 on a polycarbonate substrate 11. The recording layer 14 is made of a phase-change material, and the cover layer 17 is made of UV curing resin. The recording layer 14 is irradiated with a laser beam with a wavelength of 500 nm or less to change from a crystalline phase to an amorphous phase. The write-protect layer 15 prevents the recording layer 14 from changing back to the crystalline phase from the amorphous phase, formed by the phase change.

摘要： An optical disk includes a substrate which is formed with a plurality of grooves, and a recording layer which is provided on the substrate and which is formed of a phase-change material containing Bi, Ge, and Te. Each of the grooves is provided with a header section on which address information of the groove is recorded. The header section is formed by deflecting the grooves in the radial direction. The header sections of the respective grooves are arranged and aligned in the radial direction. Even when the address information of the predetermined groove was failed to be reproduced, the address information of the predetermined groove is specified from the address information of the adjoining groove. Accordingly, an optical disk is provided, which has a larger capacity, which has high reliability, and which is excellent in durability with respect to repeated writing of data information.

摘要： An optical disk includes a first area on which user information is recorded, and a second area in which a plurality of marks radially extending are arranged in a track direction in the optical disk. Information about the reflectance of the optical disk is recorded in the second area. It is intended to optimize the amplification factor of the reproduced signal on the basis of the information about the reflectance of the optical disk in the second area. Control data and user data can be reproduced quickly and highly reliably without depending on the relationship between the reflectances of a recording area and a non-recorded area of the optical disk.

摘要： The depth and a relative dimensional factor of a defect present in the interior of a silicon wafer are measured, and the number of such defects is calculated. A laser beam having a larger energy than the band gap of silicon is radiated obliquely to the semiconductor wafer and a scattered beam from a defect present in a subsurface layer of the wafer is detected by an image pick-up device. The temperature of the wafer is changed to at least two temperatures of T1 and T2 or to any one of plural temperatures by means of a heater and the intensity of a scattered beam is measured. It is taken into account that the light absorbance of silicon and the penetration depth of light in silicon vary depending on temperature, to determine the depth and a relative dimensional factor of an internal defect which causes scattering of light, as well as the number of such crystal defects.
