    • An optical article for playback in a player includes a first file comprising a first control logic; and a second file comprising a second control logic. The first file is configured to direct the player to play a first content data stored on the optical article, when the first control logic is read by the player. The player is directed to read the second file if the player cannot read the first file. The second file is configured to direct the player to play a second content data stored on the article when the second control logic is read by the player. The optical article includes a mark containing an optical state change material disposed on at least a portion of the first file, wherein the mark is in one of a first optical state or a second optical state, and wherein the first control logic can be read only when the mark is in the second optical state.
    • 用于在播放器中回放的光学制品包括:第一文件,包括第一控制逻辑; 以及包括第二控制逻辑的第二文件。 第一文件被配置为当播放器读取第一控制逻辑时,引导播放器播放存储在光学物品上的第一内容数据。 如果播放器无法读取第一个文件,播放器被指示读取第二个文件。 第二文件被配置为当播放器读取第二控制逻辑时,引导播放器播放存储在文章上的第二内容数据。 光学制品包括一个包含设置在第一文件的至少一部分上的光学状态变化材料的标记,其中标记处于第一光学状态或第二光学状态之一,并且其中第一控制逻辑可以是只读的 当标记处于第二光学状态时。

    • An optical article comprising a first file encoded on the optical article comprising data structure information; a second file encoded on the optical article comprising a backup of the first file; wherein at least one of the first file or the second file must be fully readable for the player to read the data on the optical article; and a mark disposed on at least a portion of the optical article where the first file is encoded and at least a portion of the optical article where the second file is encoded; wherein the mark comprises an optical state change material; wherein the optical state change material undergoes a change in its optical state when exposed to an activation signal selected from one or more of a laser, thermal energy, infrared rays, X-rays, gamma rays, microwaves, visible light, ultraviolet light, ultrasound waves, radio frequency waves, electrical energy, chemical energy, magnetic energy, and mechanical energy; wherein the optical article is transformed from a pre-activated state to an activated state when an authorized activation method is used; and wherein the optical article is transformed from a pre-activated state to an incorrectly activated state when an unauthorized activation method is used.
    • 一种光学制品,包括在光学制品上编码的第一文件,包括数据结构信息; 在所述光学制品上编码的第二文件包括所述第一文件的备份; 其中所述第一文件或所述第二文件中的至少一个必须完全可读,以供所述玩家阅读所述光学制品上的数据; 以及设置在所述第一文件被编码的所述光学制品的至少一部分上的标记以及所述第二文件被编码的所述光学制品的至少一部分; 其中所述标记包括光学状态变化材料; 其中当暴露于选自激光,热能,红外线,X射线,γ射线,微波,可见光,紫外光,超声波中的一种或多种的激活信号时,光学状态变化材料经历其光学状态的变化 波浪,射频波,电能,化学能,磁能和机械能; 其中当使用授权的激活方法时,光学制品从预激活状态转变为激活状态; 并且其中当使用未经授权的激活方法时,所述光学制品从预激活状态变换到不正确的激活状态。
