    • A method of manufacturing and a manufacturing apparatus manufacture an information recording medium constructed so that a resin layer is formed so as to cover an information layer formed on one surface of an information recording medium substrate and recording data recorded on at least the information layer can be reproduced. The resin layer is formed, while a resin layer forming sheet that has an adhesive layer formed on one surface thereof is heated, by moving at least one out of the resin layer forming sheet and the information recording medium substrate toward another out of the resin layer forming sheet and the information recording medium substrate so that the information layer-side surface of the information recording medium substrate is pressed onto the adhesive layer to stick the information recording medium substrate and the resin layer forming sheet together.
    • 一种制造方法和制造设备制造信息记录介质,其构造成使得树脂层形成为覆盖形成在信息记录介质基板的一个表面上的信息层并且记录至少记录在信息层上的数据可以是 转载。 形成树脂层,同时通过将树脂层形成片和信息记录介质基板中的至少一个从树脂层中的另一个移出,使其一个表面上形成有粘合剂层的树脂层形成片材被加热 使信息记录介质基板的信息层侧表面压在粘合剂层上,使信息记录介质基板和树脂层形成片材粘合在一起。

    • It is an object of the present invention to provide an optical recording medium wherein hardness of the surface on the incident-light side is high and warping of the optical recording medium is suppressed.The optical recording medium according to the present invention comprises a substrate 11, a recording layer 14 provided upon the substrate 11, a light transmission layer 16 made of ultraviolet curable resin provided upon the functional layer 16, and a hard-coat layer 17 provided upon the light transmission layer 16, wherein the thickness of the light transmission layer 16 is 50 μm or greater and its pencil hardness is HB or less. Thereby, warping of the optical recording medium arising due to cure shrinkage of the ultraviolet curable resin making up the light transmission layer 16 can be effectively suppressed. Moreover, the hard-coat layer 17 is provided upon this light transmission layer 16, so the occurrence of scratches on the surface of the optical recording medium can be effectively prevented.
    • 本发明的目的是提供一种光记录介质,其中入射光侧的表面的硬度高,并且抑制了光记录介质的翘曲。 根据本发明的光记录介质包括基板11,设置在基板11上的记录层14,由设置在功能层16上的紫外线固化树脂制成的透光层16和设在其上的硬涂层17 透光层16,其中透光层16的厚度为50μm以上,铅笔硬度为HB以下。 因此,可以有效地抑制由于构成透光层16的紫外线固化树脂的固化收缩而引起的光记录介质翘曲。 此外,在该透光层16上设置硬涂层17,能够有效地防止在光记录介质的表面产生划痕。

    • There is provided a mold component which makes it possible to mold a substrate for an optical recording medium which enables a functional layer having a uniform thickness to be formed thereon without using a resin-coating assisting member. A stamper holder holds a stamper thereon, and has a generally hollow cylindrical shape. An insertion hole formed through a central portion of the stamper has a diameter which is larger than an outer diameter of a cavity-side end of the stamper holder at a higher temperature of the holder than a normal temperature, and is slightly smaller than the outer diameter at the normal temperature of the holder. The cavity-side end inserted into the insertion hole at the higher temperature of the stamper is grasped by a rim of the insertion hole which is reduced in diameter at the normal temperature of the stamper.
    • 提供了一种模具部件,其可以在不使用树脂涂覆辅助部件的情况下模制用于光学记录介质的基板,从而能够在其上形成具有均匀厚度的功能层。 压模保持器在其上保持压模,并且具有大致中空的圆柱形形状。 通过压模的中心部分形成的插入孔的直径比保持器的温度高于常温的直径大于压模保持器的空腔侧端部的外径,并且略小于外部 直径在保持架的常温下。 在压模的较高温度下插入到插入孔中的空腔侧端部通过插入孔的边缘被夹持在压模的常温下直径减小。
