    • Disclosed herein are data storage media and methods of making the same. The data storage media, comprises: primary surface features disposed on at least one side of said data storage media; and secondary features superimposed over at least a portion of said surface features. In one embodiment, the method for manufacturing the data storage media comprises: disposing an identifier layer onto a surface of a stamper, said stamper having primary surface features on a first side of said stamper opposite said identifier layer; forming secondary features on an exposed surface of said identifier layer; installing said stamper into a mold; injecting a molten plastic material into the mold, wherein said molten plastic physically contacts said first side; cooling said plastic to form said data storage media, such that a positive image of said primary surface features and of said secondary features are formed into at least a portion of a surface of said plastic; and releasing said data storage media from said mold.
    • 这里公开的是数据存储介质及其制造方法。 数据存储介质包括:设置在所述数据存储介质的至少一侧上的主表面特征; 并且次要特征叠加在所述表面特征的至少一部分上。 在一个实施例中,用于制造数据存储介质的方法包括:将标识符层设置在压模的表面上,所述压模在所述压模的与所述标识层相对的第一侧上具有主表面特征; 在所述标识层的暴露表面上形成次要特征; 将所述压模安装到模具中; 将熔融的塑料材料注射到模具中,其中所述熔融塑料物理地接触所述第一侧; 冷却所述塑料以形成所述数据存储介质,使得所述主表面特征和所述次要特征的正像形成为所述塑料的表面的至少一部分; 并从所述模具中释放所述数据存储介质。

    • A method for molding an optical disk includes applying a thermally insulative mold insert onto a thermally conductive mold form by coating the mold insert on the mold form. The mold insert has a coefficient of thermal expansion compatible with the coefficient of thermal expansion of the mold form and includes an adhesion promoting material. The method further includes positioning the coated mold form in a thermally conductive mold apparatus with the mold insert positioned between the mold form and the mold apparatus; injecting a molten thermoplastic material into the mold apparatus; retaining the molten thermoplastic material in the mold apparatus for a time sufficient for the molten thermoplastic material to cool below its glass transition temperature to form the optical disk; and ejecting the optical disk from the mold apparatus.
    • 一种用于模制光盘的方法包括通过将模具插件涂覆在模具形式上将热绝缘模具插件施加到导热模具形式上。 模具插入件具有与模具形状的热膨胀系数相容的热膨胀系数,并且包括粘附促进材料。 该方法还包括将涂覆的模具形状定位在导热模具装置中,其中模具插入件位于模具形状和模具装置之间; 将熔融的热塑性材料注入模具装置中; 将熔融的热塑性材料保持在模具设备中足以使熔融的热塑性材料冷却到其玻璃化转变温度以下以形成光盘的时间; 并从模具装置中弹出光盘。
