Transformative concepts for optical data storage (ODS) applications are needed for future needs in multimedia, digital archiving, security, and many others. Commercial data storage technologies are moving to three-dimensional materials, but the known concepts suffer from limitations and high fabrication costs. Herein, a demonstrated storage medium, based on co-extruded multilayer films, overcomes these problems and allows for terabyte-level (TB), bit-by-bit optical data storage. Information in the form of complex patterns and individual bits was recorded in up to 23 superimposed layers by photobleaching a fluorescent dye via one-photon absorption. Results indicate this fabrication process is far simpler than current approaches and enables a read/write system that is nearly Blu-ray compatible, producing high-density multilayer storage media capacities orders of magnitude higher than the state of the art. The explosion of digital data of all kinds in the internet, entertainment, health care, and a plethora of other industries will require an ever increasing capacity of archival storage, data distribution and security. For example, the rapid growth of ?cloud? storage and access will require secure backup. Current manufacturers of optical data storage media have continuously reported their efforts to increase capacity and density to meet future market needs, such as super HD video. In analyzing the reported approaches, the proposed process for manufacturing multilayer polymer data storage substrates has the potential to be transformative, enabling a truly scalable, low-cost approach. In addition to potential applications in digital data storage, such films could be applicable in a number of other technologies requiring written multilayer data for secure storage.

光数据存储（ODS）应用的变革性概念需要满足未来多媒体、数字存档、安全等方面的需求。商业数据存储技术正在转向三维材料，但已知的概念受到限制和高制造成本的影响。本文中，基于共挤出多层膜的所展示的存储介质克服了这些问题，并且允许太字节（TB）级、逐位的光学数据存储。通过单光子吸收的荧光染料的光漂白，以复杂图案和单个比特形式的信息被记录在多达23个叠加层中。结果表明，这种制造过程比当前的方法简单得多，并且能够实现几乎与蓝光兼容的读/写系统，从而产生比现有技术高几个数量级的高密度多层存储介质容量。互联网、娱乐、医疗保健和大量其他行业中的各种数字数据的爆炸将需要不断增加的档案存储容量，数据分发和安全。例如，快速增长的？云？存储和访问将需要安全备份。光学数据存储介质的当前制造商已经不断地报道了他们努力增加容量和密度以满足未来的市场需求，例如超高清视频。在分析所报道的方法时，所提出的用于制造多层聚合物数据存储基板的工艺具有变革性的潜力，能够实现真正可扩展的低成本方法。除了在数字数据存储中的潜在应用之外，这种膜还可以应用于许多其他需要写入多层数据以进行安全存储的技术。
