| 20090003174 | Information Recording Medium and Method of Manufacturing the Same - An information recording medium with high recording sensitivity, superior repeat overwriting capability and favorable signal storage stability during information recording is offered. For this purpose, information recording medium | 01-01-2009 |
| 20090059758 | OPTICAL INFORMATION RECORDING MEDIUM AND METHOD FOR MANUFACTURING THE SAME - To provide an optical information recording medium having an information layer of excellent transmittance and signal intensity, an optical information recording medium | 03-05-2009 |
| 20090286037 | INFORMATION RECORDING MEDIUM, TARGET AND METHOD FOR MANUFACTURING OF INFORMATION RECORDING MEDIUM USING THE SAME - An information recording medium of the present invention includes a recording layer whose phase changes by irradiation with a laser beam or application of current. The recording layer contains, as its main component, a composite composed of Ge and Sb that are essential components, and Te that is an optional component. The composite has a composition within a region enclosed by: point (a) (35, 65, 0), point (b) (36.9, 60, 3.1), point (c) (3.2, 60, 36.8), and point (d) (5, 95, 0) in terms of a coordinate (Ge, Sb, Te)=(x, y, z) on the triangular coordinate shown in FIG. | 11-19-2009 |
| 20100151178 | INFORMATION RECORDING MEDIUM AND ITS PRODUCTION PROCESS - In each of at least two information layers ( | 06-17-2010 |
| 20100254233 | INITIALIZATION METHOD FOR INFORMATION RECORDING MEDIUM, INITIALIZATION APPARATUS FOR INFORMATION RECORDING MEDIUM, AND INFORMATION RECORDING MEDIUM - According to the present invention, a recording film is partially initialized using a first light beam (A) having a wavelength for initialization, focus adjustment is performed using a second light beam (B) having a wavelength corresponding to a wavelength for recording and reproducing information on and from an information recording medium, and then the recording film is initialized using the first light beam (A), thereby it is possible to securely initialize recording films of all information layers of a multilayer information recording medium. | 10-07-2010 |
| 20100279053 | INFORMATION RECORDING MEDIUM AND METHOD FOR PRODUCING SAME, AND SPUTTERING TARGET - An information recording medium ( | 11-04-2010 |
| 20100285263 | INFORMATION RECORDING MEDIUM AND METHOD FOR MANUFACTURING THEREOF - There is provided a dielectric material containing no sulfur (S), and there is provided an information recording medium that affords high signal quality and excellent recording sensitivity and repeated rewrite characteristics, even though no interface layer is provided between a reflective layer and a dielectric layer. To this end, the present invention is an information recording medium that is equipped with at least a recording layer and undergoes phase change when the recording layer is irradiated with a laser beam or when current is applied, comprising an oxide-fluoride dielectric layer that includes indium (In), an element M1 (where M1 is at least one element selected from among Zr, Hf, Y, Ti, Nb, Ta, Cr, Ga, and Si), oxygen (O), an element M2 (where M2 is at least one element selected from among La, Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er, Yb, Mg, Ca, and Sr), and fluorine (F). | 11-11-2010 |
| 20110058463 | OPTICAL INFORMATION RECORDING MEDIUM AND RECORDING/REPRODUCING METHOD THEREFOR - An optical information recording medium ( | 03-10-2011 |
| 20110123756 | INFORMATION RECORDING MEDIUM - An information recording medium ( | 05-26-2011 |
| 20110151277 | INFORMATION RECORDING MEDIUM - An information recording medium ( | 06-23-2011 |
