20090046566 | RECORDING LAYER FOR OPTICAL INFORMATION RECORDING MEDIUM, OPTICAL INFORMATION RECORDING MEDIUM, AND SPUTTERING TARGET FOR OPTICAL INFORMATION RECORDING MEDIUM - Provided is a recording layer for optical information storage media, which not only excels in initial reflectivity and creativity of recording marks, but also extremely excels in durability under high temperature and high humidity conditions, and which can be adequately applied to next-generation optical discs using blue-violet laser. The recording layer for optical information storage media is a recording layer to create recording marks upon irradiation with a laser beam. This recording layer is composed of a tin-based alloy containing a total of 1.0 atomic percent or more and 15 atomic percent or less of at least one selected from neodymium (Nd), gadolinium (Gd), and lanthanum (La). | 02-19-2009 |
20090211902 | SPUTTERING TARGET - The present invention provides a sputtering target in which an occurrence of target cracks can be inhibited. The sputtering target of the invention relates to a sputtering target produced by mixing and sintering a main powder containing In as a main component, which is obtained by pulverizing an ingot consisting of an intermetallic compound, and a sub-powder containing a different component composition from the above-mentioned main powder, wherein a total content of Si, Al and Fe which are unavoidable impurities is 300 ppm by mass or less. Further, the intermetallic compound contains In and at least one selected from Co and Ni. | 08-27-2009 |
20100015381 | SILVER ALLOY REFLECTIVE FILM FOR OPTICAL INFORMATION STORAGE MEDIA, OPTICAL INFORMATION STORAGE MEDIUM, AND SPUTTERING TARGET FOR THE DEPOSITION OF SILVER ALLOY REFLECTIVE FILM FOR OPTICAL INFORMATION STORAGE MEDIA - A silver alloy reflective film for optical information storage media, which can maintain superior environmental resistance, such as high hygrothermal resistance and high light stability, over the long term even when the metal reflective film is in direct contact with a resin layer. An optical information storage medium includes the reflective film and a sputtering target deposits the reflective film. The silver alloy reflective film includes one or more specific elements selected from Pr, Ho, Yb, Sm, Er, Tm, and Tb, to suppress deterioration occurring when the silver alloy reflective film is in direct contact with a resin layer, where silver in the reflective film migrates and aggregates into the adjacent resin layer. | 01-21-2010 |
20100178446 | RECORDING LAYER FOR OPTICAL RECORDING MEDIUM, SPUTTERING TARGET, AND OPTICAL RECORDING MEDIUM - Recording marks are formed in a recording layer by irradiation with a laser beam. The recording layer is made of an In-base alloy containing Ni and/or Co in a content in the range of 20 to 65 at %. Another recording layer is made of an In-base alloy containing Ni and/or Co, and containing at least one of Sn, Bi, Ge and Si in a content of 19 at % or below excluding 0 at %. An optical recording medium is provided with either of the foregoing recording layers. A sputtering target is used for forming the recording layer. The recording layer of the optical recording medium has a high reflectivity (initial reflectivity), a high C/N ratio and a low jitter. | 07-15-2010 |
20130209310 | THERMAL DIFFUSION CONTROL FILM FOR USE IN MAGNETIC RECORDING MEDIUM, FOR HEAT-ASSISTED MAGNETIC RECORDING, MAGNETIC RECORDING MEDIUM, AND SPUTTERING TARGET - A thermal diffusion control film which includes an Ag alloy containing Nd, Bi, and Si. The thermal diffusion control film can be used for a magnetic recording medium for heat-assisted magnetic recording. The thermal diffusion control film has a good heat resistance even after heat hysteresis at about 600° C. | 08-15-2013 |
