MRI: Spinstand for Developing Next Generation Data Storage Systems

在本提案中，研究人员寻求资金购买Spinstand系统，这是测试和开发下一代磁性和替代记录系统不可或缺的工具。spinstand V2002系统由三部分组成：1)spinstand V2002是该领域的领导者Guzik公司的最新型号，与以前的型号不同，它除了使用线性电机外，还使用压电致动器，沿指定轨迹定位精度为1nm的磁头；2)读写分析仪RWA2004也是Guzik公司的最新型号，最大数据速率可达4千兆/秒（这是目前商用产品中最高的数据速率）；3)雷蒙EMC的射频屏蔽外壳，用于保护测量免受杂散电磁场的影响。这些仪器的总费用是315,565美元。在信息技术飞速发展的今天，预计下一代数据存储系统（在未来十年内）应能够存储、记录和检索有效面密度超过10tb /in2、数据速率超过1gbit /sec的数据。在如此高的数据密度下，美国国会的整个图书馆可以被记录在一个普通音乐CD大小的设备中。测试下一代记录系统对系统的机械和电气部件的要求非常严格。此外，在处理如此大量的信息时，必须具有最大可能的数据速率。pi寻求购买的独特Spinstand系统能够测试具有如此高数据密度的记录系统。此外，该系统提供了当今业界最佳的数据速率。PIs计划购买Spinstand系统，目的是开发下一代数据存储技术，包括：1)磁纵向和垂直记录，面密度超过1tb /in2；2)面密度超过10太比特/in2的热辅助磁记录（HAMR）；3)面密度超过10tb /in2的图案化介质；4)面密度超过10tb /in2的非常规蛋白质存储；在上面的列表中，后三种（尤其是基于蛋白质的存储）应用通常被公司贴上高风险的标签，因为它们非常非常规。出于经济原因，如果可能的话，公司更愿意把他们的研究和开发集中在对现有技术的真正增量改进上。围绕该仪器的研究旨在开发下一代数据存储系统，包括磁性和非常规技术，如基于蛋白质的存储。通过购买Spinstand系统，pi计划将开放的学术环境与他们的经验和与行业的紧密联系结合起来，开发一些高风险和创新的数据存储技术。在这个过程中，pi计划将Spinstand整合到他们最近在佛罗里达国际大学（FIU）和休斯顿大学（UH）建立的最先进的基础设施中。例如，应该提到的是，在FIU购买最先进的Spinstand系统的主要原因之一是关闭FIU最近为纳米级磁性器件的先进原型而建立的实验回路。最后，这项研究工作与金融大学最近扩大其在前沿科学和技术领域的研究活动的战略决策是一致的。此外，两所大学参与这项研究，自动拓宽了对该提案结果的兴趣领域。项目概述：所提出的研究课题的应用范围非常广泛，汇集了来自不同学科的研究人员，包括电气工程、机械工程和材料科学、生物工程、物理学和信号处理。相信这种跨学科的互动将导致具有突破性科学成果的协同活动。

Intellectual MeritIn this proposal, investigators seek funding to purchase a Spinstand System an indispensable tool to test and develop next generation magnetic and alternative recording systems. The spinstand system consists of three parts: 1) Spinstand V2002 the latest model by the leader in the field Guzik Corporation unlike the previous models, it uses a piezoactuator, besides linear motors, to position a head with 1-nm accuracy along a specified track; 2) Read-Write Analyzer RWA2004 also the latest model by Guzik Corporation is capable of the maximum data rate of 4 Gigabit/sec (This is the record-high number among the commercial available products.); and 3) Radio-Frequency (RF) Shielded Enclosure by Raymond EMC necessary to protect the measurements from the stray electromagnetic fields. The total cost for the instrumentations is $315,565. With a rapid progress in information technologies today, it is expected that next generation data storage systems (within the next decade) should be capable of storing, recording and retrieving data with an effective areal density of beyond 10 Terabit/in2 and with a data rate of more than 1 Gbit/sec. At such high data density, the entire library of the U.S. Congress can be recorded in a device the size of a regular music CD. The requirements to the mechanical and electrical parts of a system to test next generation recording systems are unconventionally tight. Also, it is imperative to have the maximum possible data rate when dealing with such massive amounts of information. The unique Spinstand system the PIs seek to purchase is capable of testing recording systems with such high data density. In addition, the system offers the best data rate available in the industry today. The PIs plan to purchase the Spinstand system with the purpose to develop next generation data storage technologies including:1) Magnetic longitudinal and perpendicular recording for areal densities beyond 1Terabit/in2;2) Heat-assisted magnetic recording (HAMR) for areal densities beyond 10 Terabit/in2;3) Patterned media for areal density beyond 10 Terabit/in2;4) Unconventional Protein-based storage for areal density beyond 10 Terabit/in2;In the list above, the last three (especially, the protein-based storage) applications are often labeled as high-risk by companies because of their quite unconventional nature. For economical reasons, if possible, companies prefer to concentrate their research and development on truly incremental improvement of the existing technologies. Broader Impact The research around the instrumentation is directed to develop next generation data storage systems including both magnetic and unconventional technologies such as protein-based storage. With the purchase of the Spinstand system, the PIs plan to integrate the open academic environment with their experience and strong ties to the industry to develop some of the most high-risk and innovative data storage technologies. In this process, the PIs have a plan to integrate the Spinstand in the state-of-the-art infrastructure they have recently built in their institutions, Florida International University (FIU) and the University of Houston (UH). For example, it should be mentioned that one of the main reasons to purchase the state-of-the-art Spinstand system at FIU is to close the experimentation loop built recently at FIU for the advanced prototyping of Nanoscale magnetic devices. Finally, this research effort goes along with the FIU's recent strategic decision to expand its research activities in the cutting edge areas of science and technology. In addition, the involvement of two universities in this research automatically broadens the field of interest in the results coming from this proposal. PROJECT SUMMARYA very broad range of applications of the proposed research topics brings together researchers from different disciplines of science, Electrical Engineering, Mechanical Engineering and Materials Science, Bioengineering, Physics, and Signal Processing. It is believed that this interdisciplinary interaction will result in synergetic activities with the ground-breaking scientific results.
