摘要： Provided is an Sb-Te alloy sintered compact target using atomized powder consisting of substantially spherical particles of an Sb-Te alloy, wherein the spherical atomized powder consists of particles that were crushed and flattened, and the flattened particles exhibiting a ratio (flatness ratio) of short axis and long axis of 0.6 or less occupy 50% or more of the overall particles. With this Sb-Te alloy sintered compact target, particles exhibiting a long axis orientation aligned within ±45° in a direction that is parallel to the target surface occupy 60% or more of the overall particles. In addition, the oxygen concentration in this Sb-Te alloy sintered compact target is 1500wtppm or less. Thus, the Sb-Te alloy sputtering target structure can be uniformalized and refined, generation of cracks in the sintered target can be inhibited, and generation of arcing during sputtering can be inhibited. Further, surface ruggedness caused by sputter erosion can be reduced in order to obtain a high quality Sb-Te alloy sputtering target.
摘要翻译：提供一种Sb-Te合金烧结体，其使用由Sb-Te合金的大致球状的粒子组成的雾化粉末，其中，所述球状雾化粉末由粉碎扁平的粒子构成，平坦化粒子的比例（平坦度比）的短轴和长轴为0.6以下，占总粒子的50％以上。利用该Sb-Te合金烧结体靶，在与靶表面平行的方向上排列在±45°以内的长轴取向的粒子占总体粒子的60％以上。此外，该Sb-Te合金烧结体靶的氧浓度为1500重量ppm以下。因此，可以使Sb-Te合金溅射靶结构均一化和细化，可以抑制烧结靶中的裂纹的产生，并且可以抑制溅射中的电弧放电。此外，为了获得高质量的Sb-Te合金溅射靶，可以减少由溅射侵蚀引起的表面粗糙度。

摘要： The optical recording medium has a recording layer sensitive for recording at a first wavelength and sensitive for reading at a second wavelength, the recording layer having a groove structure, wherein at the first wavelength the groove structure has a diffraction efficiency into a first diffraction order sufficiently large to generate a push-pull signal, and at the second wavelength it has a diffraction efficiency into a first diffraction order close to zero. The optical pickup for recording on an optical recording medium intended to be read with a second wavelength and a second numerical aperture is characterized in that it has a light source for generating a light beam at a first wavelength and a numerical aperture given by the second numerical aperture multiplied with a ration of the first wavelength and the second wavelength.
