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.

这项小企业创新研究（SBIR）第一阶段项目旨在为多层光存储技术开发一种超快速数据检索方法。该存储技术使用具有独特光学特性的N对手性薄膜的3-D堆叠。手性堆叠可以提供非常高的面积数据存储密度，每层100 Mb/ cm2，等效体积密度为0.5 Tb/ cm2。该数据检索方法采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。所提出的技术每次读出操作可以检索2NB位，其中块大小B可以是100 MB或更高。检索速率大于6n Gb/s是可行的，对单对薄膜的检索速率为6g /s。由于数字信号处理和CMOS成像芯片技术的最新进展，该检索方法利用了大量并行性，并且很容易实现。第一阶段将演示从一对堆叠的手性存储薄膜（N=1）中读取块，并将为块读取和写入开发最佳的数据组织方案。第二阶段将开发、建造和演示原型。第三阶段将开发产品原型，以实现商业化。所提出的数据检索方法提供了数量级的吞吐量增加，这将有利于计算性能的所有领域。这些改进将有利于科学、工程、商业和家庭计算，以及军事C3I。
