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快速数据检索方法。存储器技术使用具有独特光学特性的N对手性膜的3-D堆叠。手性叠层可以提供每层100 Mb/cm 2的非常高的面数据存储密度，等效体积密度为0.5 Tb/cm 3。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，以检索一个大的数据块在一个单一的步骤。所提出的技术可以在每个读出操作中检索2NB位，其中块大小B可以是100 MB或更高。对于单对膜，大于6 N Gb/s或6 G/s的检索速率是可行的。检索方法利用大量的并行性，是很容易实现的数字信号处理和CMOS成像芯片技术的最新进展。第一阶段将展示从一对堆叠的手性存储膜（N=1）的块读出，并将开发用于块阅读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。第三阶段将开发产品原型，导致商业化。所提出的数据检索方法提供了数量级的吞吐量增加，这将有利于所有领域的计算性能。这些改进将有利于科学，工程，商业和家庭计算，以及军事C3 I。

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.
