摘要： A single-sided ablative write-once optical disk is usable without a protective cartridge. The disk includes the conventional radiation-transparent polycarbonate substrate that has one surface serving as the disk outer face and an opposite surface that supports the fluorinated hydrocarbon subbing layer and the tellurium-based active data layer. The tellurium alloy in the data layer flows to form holes when subjected to incident laser radiation through the substrate. A multilayer protective coating is formed over the tellurium-based layer and has an outer surface that serves as the other outer face for the disk. The multilayer protective coating includes a deformable layer formed directly on the tellurium-based layer and a scratch-resistant hardcoat formed on the deformable layer. The deformable layer has sufficient hardness and modulus of elasticity to permit the tellurium alloy to flow at conventional laser power levels. In one embodiment the deformable layer is a silicone elastomer. In another embodiment the deformable layer is a fluorinated hydrocarbon, and a metal layer, such as an aluminum-chromium alloy, is formed between the deformable layer and the hardcoat.
摘要翻译：单面烧写一次写入光盘可以在没有保护盒的情况下使用。盘包括具有一个表面用作盘外表面的常规辐射透明聚碳酸酯基底和支撑氟化烃底层和碲基活性数据层的相对表面。当通过基板进行入射激光辐射时，数据层中的碲合金流动形成孔。在碲基层之上形成多层保护涂层，并且具有用作盘的另一外表面的外表面。多层保护涂层包括直接形成在碲基层上的可变形层和形成在可变形层上的抗划伤硬涂层。可变形层具有足够的硬度和弹性模量，以允许碲合金以常规激光功率水平流动。在一个实施方案中，可变形层是有机硅弹性体。在另一个实施方案中，可变形层是氟化烃，并且在可变形层和硬涂层之间形成金属层，例如铝 - 铬合金。
