摘要： At least one information layer including a recording layer contains a material that can exhibit a transition between two optically different states in response to irradiation with a laser beam as a main component is provided on a substrate, and the material is configured so as to exhibit an energy gap ranging from 0.9 eV to 2.0 eV in the amorphous state. The information layer is configured to have a light transmittance of not less than 30 % when irradiated with a laser beam having a wavelength ranging from 300 nm to 450 nm. It is possible to achieve excellent recording/reproduction, even if a plurality of recording layers are provided in the recording medium, when this medium is irradiated with a laser beam with a wavelength in the foregoing range from one side of the medium.

摘要： PROBLEM TO BE SOLVED: To make manufacturing of, for example, a BD-R disk significantly efficient and reduce cost. SOLUTION: Upon sputtering of an information recording layer, a single film is formed with the same material (for example, In-Sn-Pd-O film), layers where film forming conditions are changed are formed to make a pseudo multi-film structure. For example, by changing a flow rate of O 2 and a value of a gas pressure, a layer where oxidation of Pd is suppressed is formed. By this means, a film portion where durability is improved is formed and overall durability of the information recording layer is improved. A sputtering device can be obtained with one chamber only by changing the film forming conditions, so that it is possible to obtain improvement of manufacturing efficiency and cost reduction.
