摘要： A stamper-forming electrode material contains Cu as its main ingredient and at least one other element, preferably Ag and/or Ti. It is preferred that the Ag content be 10.0 wt % or less and that the Ti content be 5.0 wt % or less. A stamper-forming thin film is made of this stamper-forming electrode material, whereby its corrosion resistance is improved to suppress damage to itself, and a high-quality stamper can hence be formed.
摘要翻译：压模形成电极材料包含Cu作为其主要成分和至少一种其它元素，优选Ag和/或Ti。 Ag含量优选为10.0重量％以下，Ti含量为5.0重量％以下。压模形成薄膜由该压模形成用电极材料制成，由此其耐腐蚀性得到改善以抑制其自身的损伤，因此可以形成高质量的压模。

摘要： An information recording medium using a substrate having light transmittancy permitting high density recording to be achieved and a recording method permitting such an information recording medium using a substrate having light transmittancy to be recorded in a high density are provided. The information recording medium is formed by layering an ITO film and EB resist on a transparent insulating substrate formed of a glass material having light transmittancy. At the time of recording information, as the ITO film is set at a ground potential, an electron beam having recording information is irradiated upon a surface of the EB resist for a prescribed scanning to perform electron beam exposure, and pits corresponding to the information to be recorded are formed at the exposed positions.

摘要： An information recording apparatus and a method therefor which can form a beam guide groove in the shape of highly accurate rectangle having abrupt edges. A recording mark is formed by exposing a recording medium with a recording beam having a beam diameter smaller than the beam guide groove, while periodically vibrating the recording beam in a direction perpendicular to a recording track on the recording medium, or in both horizontal and vertical directions of the recording track. For this purpose, the information recording apparatus for forming a recording mark of a predetermined width in accordance with recording information on a recording surface of an information recording medium comprises, in addition to components conventionally provided therein, recording beam generator for generating a recording beam having a smaller diameter than the width of the recording mark, a displacement information generator for generating displacement information of the recording beam based on the generated recording information, and a beam position controller for offsetting the recording beam based on the displacement information.
