STTR Phase I: Multilevel Magnetic Recording for Areal Densities Above 10 Terabit-per-square-inch

小型企业创新研究(SBIR)第一阶段将研究多级磁记录技术的可行性。这项技术可能适用于密度超过10太比特/英寸，数据速率超过1千兆比特/英寸的设备。该项目将包括研究行业标准旋转，以实现能够实现超过16个信号电平的设备原型，以存储有效航空密度超过1太比特/英寸的信息，并展示将该技术扩展到10太比特/英寸以上的潜力。概念验证系统将由一个高场换能器组成，该换能器是通过对常规磁记录头和三维(3D)介质进行聚焦离子束微调而建立的。为了证明多级记录的可行性，创新的多级编码通道将被集成到最先进的Spinstand Guzik V2002中。新通道的自旋测试将用于将3D记录介质和换能器结合到一个可行的多级记录系统中。如果成功，这一具有成本效益的长期解决方案的可行性研究结果可能会对数十亿美元的数据存储行业产生重大影响。随着多级信号处理的引入，这一拟议的解决方案有可能超越现有的信息相关技术。引入多电平信号格式不仅可以使与数据存储相关的应用受益，还可以使其他电子应用受益。

The Small Business Innovation Research (SBIR) Phase I will study the feasibility of the technology of multilevel magnetic recording. This technology is potentially suitable for densities beyond 10 terabit/in2 and data rates faster than 1 gigabit/s. This project will include the study of the industry standard spinstand for a device prototype capable of achieving more than 16 signal levels to store information with effective aerial densities above 1 terabit/in2 and demonstrate a potential to extend the technology beyond 10 terabit/in2. The proof of concept system will consist of a high-field transducer built via focused ion beam trimming of regular magnetic recording heads and three-dimensional (3D) media. To prove the feasibility of multilevel recording, the innovative multilevel encoding channel will be integrated into a state-of-the art spinstand Guzik V2002. Spinstand testing with the new channel will be used to combine 3D recording media and transducers into a viable multilevel recording system. If successful the outcome of the feasibility study for this cost-effective and long-term solution may have great impact on the multibillion data storage industry. With the introduction of multilevel signal processing this proposed solution has potential to leapfrog the existing information related technologies. Not only data storage related but also other electronics applications could benefit from the introduction of multilevel signal format.
