    • In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on an upper surface of the first photoresist layer within a predetermined temperature range, to thereby form an intermediate conductive film. An intermediate conductive film is patterned. A second photoresist layer is formed on an exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, and on an upper surface of the intermediate conductive film remaining after patterning. The second photoresist layer is divided into a second soluble portion and a second insoluble portion. Next, the first and second photoresist layers are developed, and the first and second soluble portions are removed.
    • 在电铸模具的制造方法中,在基板的底部导电膜的上表面上形成第一光致抗蚀剂层,将第一光致抗蚀剂层分割为第一可溶部分和第一不溶部分。 导电材料在预定温度范围内热沉积在第一光致抗蚀剂层的上表面上,从而形成中间导电膜。 对中间导电膜进行图案化。 在除去中间导电膜之后,在图案化之后残留的中间导电膜的上表面上,在第一光致抗蚀剂层的暴露的上表面上形成第二光致抗蚀剂层。 第二光致抗蚀剂层被分成第二可溶部分和第二不溶部分。 接下来,使第一和第二光致抗蚀剂层被显影,并且去除第一和第二可溶部分。

    • An information reproducing apparatus has a medium with a linear tracking mark extending in a scanning direction and a linear data mark extending in a direction orthogonal to the scanning direction. A light control unit irradiates the data mark with a first near-field light polarized in the scanning direction and irradiates the tracking mark with a second near-field light polarized in the direction orthogonal to the scanning direction. A detector detects light scattered by the data mark and the tracking mark irradiated with the first near-field light and the second near-field light, respectively. A signal processing unit processes a first output signal from the detector corresponding to the detected light scattered by the data mark and processes a second output signal from the detector corresponding to the detected light scattered by the tracking mark. The signal processing unit has a control circuit that carries out tracking control in accordance with an intensity of the second output signal and that carries out access control in accordance with an intensity of the first output signal.
    • 一种信息再现装置具有在扫描方向上延伸的线性跟踪标记的介质和在与扫描方向正交的方向上延伸的线性数据标记。 光控制单元以沿扫描方向偏振的第一近场光照射数据标记,并以与扫描方向正交的方向偏振的第二近场光照射跟踪标记。 检测器分别检测由第一近场光和第二近场光照射的数据标记和跟踪标记所散射的光。 信号处理单元处理来自检测器的对应于由数据标记散射的检测到的光的第一输出信号,并且处理来自检测器的对应于由跟踪标记散射的检测到的光的第二输出信号。 信号处理单元具有控制电路,该控制电路根据第二输出信号的强度执行跟踪控制,并根据第一输出信号的强度进行访问控制。
