SBIR Phase I: Ultrafast Block Retrieval for Optical Storage

这个小型企业创新研究(SBIR)第一阶段项目旨在开发一种用于多层光存储技术的超高速数据检索方法。这种存储技术使用N对手性薄膜的三维堆叠，这些薄膜具有独特的光学特性。手性堆栈可以提供非常高的面数据存储密度，每层100Mb/cm2，当量体积密度为0.5Tb/cm3。该数据检索方法使用图像捕获和模式识别技术，而不是通常的逐位读出技术，在单个步骤中检索大块数据。所提出的技术可以在每次读出操作中检索2nb比特，其中块大小B可以是100MB或更高。超过6N GB/S的检索率是可行的，或者单对电影的检索率为6G/S是可行的。这种检索方法利用了大量的并行性，由于数字信号处理和cmos成像器芯片技术的最新进展，很容易实现。第一阶段将演示从一对堆叠的手性存储薄膜(N=1)中进行块读出，并将开发用于块读取和写入的最佳数据组织方案。第二阶段将开发、建造和演示原型。第三阶段将开发导致商业化的产品原型。拟议的数据检索方法在吞吐量方面提供了数量级的增长，这将使计算性能的所有领域受益。除了军用C3I，这些改进还将使科学、工程、商业和家庭计算受益。

This Small Business Innovation Research (SBIR) Phase I project is designed to develop an ultra-fast data retrieval method for multi-layered optical memory technology. The memory technology uses 3-D stacking of N paired chiral films with unique optical properties. The chiral stack can provide very high areal data storage densities of 100 Mb/cm 2 per layer with an equivalent volumetric density of 0.5 Tb/cm 3 . The data retrieval method uses image capture and pattern recognition techniques instead of the usual bit-by-bit read out technique to retrieve a large block of data in a single step. The proposed technique can retrieve 2NB bits per readout operation, where the block size B can be 100 MB or higher. Retrieval rates of more than6N Gb/s are feasible or 6 G/s for a single pair of films. The retrieval method utilizes massive parallelism and is readily achievable thanks to recent progress in digital signal processing and CMOS imager chip technologies. Phase I will demonstrate block readout from a pair of stacked chiral storage films (N=1) and will develop optimal data organization schemes for both block reading and writing. Phase II will develop, build and demonstrate prototypes. Phase III will develop product prototypes that lead to commercialization.The proposed data retrieval method provides orders-of-magnitude increases in throughput that will benefit all areas of computing performance. The improvements will benefit scientific, engineering, business and home computing, in addition to the military C3I.
