    摘要: According to one embodiment, in a multilayered write once information recording medium, the light reflectance of a recording mark formed in a first recording film by irradiation with a short-wavelength laser beam is higher than a light reflectance before irradiation with the short-wavelength laser beam, the light reflectance of a recording mark formed in a second recording film by irradiation with the short-wavelength laser beam is higher or lower than a light reflectance before irradiation with the short-wavelength laser beam, and the light reflectance of a recording mark formed in a third recording film, which is arbitrarily formed, by irradiation with the short-wavelength laser beam is higher or lower than a light reflectance before irradiation with the short-wavelength laser beam.

    摘要: A first recording film, interlayer, and second recording film are formed on a transparent resin substrate having a groove and land. A recording mark is formed by irradiation with a short-wavelength laser beam. The light reflectance of the recording mark formed by irradiation with the short-wavelength laser beam is higher than a light reflectance before irradiation with the short-wavelength laser beam. The groove wobbles within a predetermined amplitude range. A resin material forming the interlayer is a polymer material containing carbon, hydrogen, nitrogen, and oxygen as main components. The oxygen atomic ratio is 11 atm % or more, or the push-pull signal modulation degree is 0.26 or more.

    摘要: An information recording medium having a disc shape and a recording layer configured to store information by light, the information being configured to be recorded on the recording layer with a mark and a space, wherein a channel clock period, represented by T, is provided for recording the mark on the recording layer. A mark corresponding to 2T or more can be recorded, and write parameter information is recorded on a particular area of the information recording medium. The parameter information includes a first peak power value used for a standard recording speed, and a second peak power value used for an increased recording speed which is a quadruple of the standard recording speed, the second peak power value being greater than the first peak power value.
