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.

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。该技术可能适用于超过10太比特/平方英寸的密度和超过1千兆比特/秒的数据速率。该项目将包括研究工业标准自旋支架，用于能够达到16个以上信号电平的设备原型，以有效空间密度超过1太比特/平方英寸的方式存储信息，并展示将该技术扩展到10太比特/平方英寸以上的潜力。概念验证系统将包括一个高场传感器，该传感器通过聚焦离子束修整常规磁记录头和三维（3D）介质而构建。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一个国家的最先进的spinstand Guzik V2002。使用新通道的旋转支架测试将用于将联合收割机3D记录介质和换能器组合成一个可行的多级记录系统。如果成功的话，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数据存储行业产生重大影响。随着多级信号处理的引入，所提出的解决方案具有跨越现有信息相关技术的潜力。不仅与数据存储相关，而且其他电子应用也可以从多级信号格式的引入中受益。
