This Small Business Innovation Research (SBIR) Phase I project studies a new coding and implementation techniques for high-speed high-density optical disk data storage. It is well known that conventional optical disk storage is based on recording and readout binary data pits in an optical disk such as compact disk and DVD. The data storage density is thus limited by the size of these pits that can be recorded and readout optically due to diffraction limitation. This proposed research explores a new coding concept and uses an extended depth of focus diffractive optical element to facilitate recording and readout many bits of data in a single storage pit. The data storage density can thus be significantly increased. The novel approach can potentially reach 50 Gbits/in storage density using the same optical and motion scanning system as DVD and using a commercially available data recording material. Thus, the technology development can reach its near-term maturity. Phase I research will demonstrate the feasibility of the proposed novel disk storage concept. Compatibility with existing data storage technology will also be demonstrated.The research will develop a simple proof-of-concept high-density optical disk storage prototype based on a new coding concept. Implementation of such coding concept can significantly increase the disk storage density for commercial and military applications such as computer data storage, on-line storage, library archival applications, image storage and processing for medical applications, and military target identification and fast access to large intelligent database.

这个小型企业创新研究(SBIR)第一阶段项目研究了一种用于高速高密度光盘数据存储的新编码和实现技术。众所周知，传统的光盘存储是基于在诸如光盘和DVD的光盘中记录和读出二进制数据凹坑。因此，由于衍射限制，数据存储密度受到这些凹坑的尺寸的限制，这些凹坑可以被光学地记录和读出。这项研究探索了一种新的编码概念，并使用扩展的焦深衍射光学元件来促进在单个存储凹坑中记录和读出许多比特的数据。因此，可以显著提高数据存储密度。该新方法使用与DVD相同的光学和运动扫描系统并使用商业上可获得的数据记录材料，潜在地可以达到50Gbit/in的存储密度。这样，技术发展才能达到近期的成熟度。第一阶段的研究将证明提出的新的磁盘存储概念的可行性。研究还将展示与现有数据存储技术的兼容性。研究将基于新的编码概念开发一种简单的概念验证高密度光盘存储原型。这种编码概念的实施可以显著提高商业和军事应用的磁盘存储密度，如计算机数据存储、在线存储、图书馆档案应用、医疗应用的图像存储和处理，以及军事目标识别和快速访问大型智能数据库。
