| 20080233328 | INFORMATION MEDIUM - An information medium includes a reflective layer with Ag as a main constituent, a sulfide species dielectric layer, and a recording layer in the mentioned order on a surface of a substrate. Data is recorded and reproduced by emitting a laser beam from an opposite side of the recording layer to the substrate. A barrier layer with an oxide of Zn as a main constituent is formed between the reflective layer and the sulfide species dielectric layer. | 09-25-2008 |
| 20090022030 | OPTICAL INFORMATION MEDIUM - An optical information medium includes a substrate and a recording layer formed on the substrate. The recording layer includes a first recording film formed of a first material that has Si as a main constituent and a second recording film that is formed of a second material that has Cu as a main constituent and to which Sn is added, the second recording film being formed in a periphery of the first recording film. Data is recorded onto and reproduced from the recording layer by irradiation of the recording layer with a laser beam. | 01-22-2009 |
| 20090029089 | OPTICAL INFORMATION MEDIUM - An optical information medium includes a substrate and a recording layer formed on the substrate. The recording layer includes a first recording film formed of a first material that has Si as a main constituent and a second recording film that is formed of a second material that has Cu as a main constituent and to which Ni is added, the second recording film being formed in a periphery of the first recording film. Data is recorded onto and reproduced from the recording layer by irradiation of the recording layer with a laser beam. | 01-29-2009 |
| 20090029090 | OPTICAL INFORMATION MEDIUM - An optical information medium includes a substrate and a recording layer formed on the substrate.

| 20090141609 | MULTI-LAYERED OPTICAL RECORDING MEDIUM AND METHOD FOR OPTICAL RECORDING AND READING - A multi-layered optical recording medium is provided of which the manufacturing costs is significantly reduced. The multi-layered optical recording medium has multiple information recording layers and at least two layers of the information recording layers have the same medium-side address information. This configuration allows for reducing the types of master stampers and thus reducing manufacturing costs. | 06-04-2009 |
| 20100296377 | METHOD OF EVALUATING CHARACTERISTICS OF MULTILAYER OPTICAL RECORDING MEDIUM - A multilayer optical recording medium having three or more information recording layers is irradiated with a laser beam, and a first signal obtained from the reflected laser beam is subjected to a frequency filter. A second signal obtained by filtration through a high-pass filter is used to evaluate the characteristics of the multilayer optical recording medium. In this manner, even in a multilayer optical recording medium having three or more information recording layers, the influence of the variation of the thickness and material of the information recording layers and the influence of the variation of the thickness of a spacer layer can be clearly determined and evaluated. | 11-25-2010 |
| 20110050082 | ORGANIC ELECTROLUMINESCENT LIGHT SOURCE - An organic electroluminescent light source device includes, in the following order from a light-emitting surface side, a first transparent electrode layer, a luminescent layer, a second transparent electrode layer, and a reflecting layer, wherein the reflecting layer includes a concavo-convex structure with an average inclination angle of 12 to 45°. An organic electroluminescent light source device includes, in the following order, a first transparent electrode layer, a luminescent layer, a second transparent electrode layer, a diffusing layer, and a reflecting-scattering layer, wherein the diffusing layer has a concavo-convex surface including a concavo-convex structure with an average inclination angle of 17 to 45°. | 03-03-2011 |
| 20110076436 | OPTICAL RECORDING MEDIUM AND METHOD FOR MANUFACTURING THE SAME - An optical recording medium having three or more information recording layers reduces crosstalk caused by multi-reflected beams and improves signal quality. In the optical recording medium having three or more information recording layers, the refractive index of a plurality of intermediate layers disposed between adjacent information recording layers is greater than the refractive index of a cover layer disposed between a light incident surface and an information recording layer being the closest from the light incident surface. | 03-31-2011 |
