    摘要： To accomplish write-once type optical recording mediums that have excellent recording and reproducing characteristics and producibility and that are capable of being fabricated at low cost. A write-once type optical recording medium 10 has the structure of which an inorganic recording film 6, a dielectric film 4, and a light transmission layer 5 have been successively formed on a substrate 1. The inorganic recording film 6 is composed of a metal film 2 and an oxide film 3 successively formed on the substrate 1. When light is radiated to the inorganic recording film 6, oxygen is separated from the oxide film 3 due to the light catalyst effect, resulting in increasing the oxygen concentration on the metal film 2 side and largely varying the optical constant.

    摘要： A write once optical recording medium has an inorganic recording film which includes an oxide film having germanium oxide (GeO) as a principal component, and a metal film adjacent to the oxide film, the metal film having a titanium/silicon alloy (TiSi) as a principal component. According to this arrangement, it is possible to construct an inexpensive write once optical recording medium with large strength capable of high density recording by using a short wavelength light source and an optical system with a high numerical aperture having excellent characteristics.

    摘要： To obtain high durability even when a recording material which causes big cubical expansion is used for a recording film of an information recording medium. An information recording medium 10 comprises a substrate, a recording film provided on the substrate, and a dielectric film provided on the substrate. The recording film is made of recording material configured to cause cubical expansion by light energy irradiation. The dielectric film is made of ZrO2 and Cr2O3. This prevents the generation of cracks in the dielectric film 4 and the immersion of moisture to the recording film 6 even when the recording material causes cubical expansion due to light energy irradiation.
