    • Methods and apparatus are provided for making an optically readable storage media in which the reading beam passes through a bonding layer configured with a reactive material that transforms from an optically transparent state to an optically opaque state after exposure to a predefined stimulus, thereby inhibiting access to the data encoded on the optically readable storage media. The method includes steps of synthesizing a blocked dye combining the blocked dye with a carrier material curing the resultant combination deblocking the dye to produce a reduced dye in the resultant bonding layer exposing the optically readable storage media with the reactive material in its bonding layer to a predetermined stimulus. In a further aspect of the present invention methods and apparatus are provided for making an optically readable storage media wherein the reading light passes through the bonding layer and the data encoded information is encoded on the L1 substrate. In yet another aspect of the present invention methods and apparatus are provided for making an optically readable storage media with at least two mechanisms for limiting access to the encoded data of the optically readable storage media.
    • 提供了用于制造光学可读存储介质的方法和装置,其中读取光束通过配置有在暴露于预定义的刺激之后从光学透明状态转换为光学不透明状态的反应性材料的结合层,从而禁止访问 编码在光学可读存储介质上的数据。 该方法包括以下步骤:合成封闭的染料与封端染料组合的载体材料,固化所得组合物解封染料以在所得粘合层中产生还原染料,将光学可读存储介质与其结合层中的反应性材料暴露于 预定刺激。 在本发明的另一方面,提供了用于制造光学可读存储介质的方法和装置,其中读取光通过结合层并且数据编码信息被编码在L 1衬底上。 在本发明的另一方面,提供了用于制造具有用于限制对光学可读存储介质的编码数据的访问的至少两种机制的光学可读存储介质的方法和装置。

    • Limited play optical discs (LPOD's) are optical discs readable by a reading device for a limited period of time. After removal from it's packaging, an LPOD becomes unusable after a relatively short period of time. LPOD's can be provided with a limited shelf life by storing the LPOD's in a special package. The packaging includes a portion that controls the environment inside the package until a preset period of time passes, at which point reading-inhibit action of a material in the optical disc is allowed to go forward, which causes the disc to become unreadable. Hence, once the product exceeds its shelf life, it becomes unusable regardless of whether or not the package has been opened.
    • 有限播放光盘(LPOD)是读取设备在一段有限的时间内可读的光盘。 在从包装中取出后,LPOD在相对较短的时间内变得不可用。 LPOD可以通过将LPOD存储在特殊包装中而提供有限的保质期。 包装包括控制包装内的环境的部分,直到经过预设的时间段,此时光盘中的材料的禁止读取动作被允许向前移动,这导致盘变得不可读。 因此,一旦产品超过其保质期,无论包装是否打开,它都不可用。
