The objective of this research is to develop signal processing system design solutions to enable high-performance and low-cost hybrid solid-state/magnetic hard disk drives with beyond 1 Tbit per square inch areal density. The proposed research aims to cohesively develop powerful signal processing algorithms and low-cost VLSI architecture solutions that can simultaneously address the low signal-to-media-noise ratio and high system fault tolerance implementation cost faced by the emerging hybrid shingled written recording systems. The intellectual merit of this proposal lies in the theme of developing unified signal processing system design solutions from both theory and practical implementation perspectives. New non-controllable trellis-based finite-state detectors and their efficient VLSI architectures will be developed to address the loss of signal-to-media-noise ratio caused by shingled writing. A unified read channel design approach and a data-management-aware signal processing strategy will be further developed to reduce the overall system signal processing implementation cost. The broader impact of the proposed research is that it will enable the development of low-cost ultra-high capacity mass data storage drives to accommodate the exploding global data volume. It also contributes greatly to sustaining the historical magnetic recording areal density growth rate, providing a direct benefit to this strategically important high technology sector critical to the economic health of the nation. Extra effort will be made to recruit women and other under-represented groups as research assistants in this project, involve representatives of the Pacific Islander minority as undergraduate researchers, and reach out to high school students as part of outreach efforts.

本研究的目标是开发信号处理系统设计解决方案，以实现高性能和低成本的混合固态/磁性硬盘驱动器，其面密度超过每平方英寸1兆比特。本研究旨在集中开发强大的信号处理算法和低成本的VLSI架构解决方案，同时解决新兴混合瓦式书写记录系统所面临的低信噪比和高系统容错实现成本问题。本方案的智力优势在于从理论和实际实现的角度开发统一的信号处理系统设计方案。将开发新的基于不可控制栅格的有限状态检测器及其高效的VLSI架构，以解决由瓦片写入引起的信噪比损失。将进一步开发统一的读通道设计方法和数据管理感知信号处理策略，以降低整个系统信号处理的实现成本。拟议研究的更广泛影响是，它将使开发低成本超高容量大容量数据存储驱动器能够适应爆炸式增长的全球数据量。它还有助于保持历史磁记录面密度增长率，为这个对国家经济健康至关重要的具有战略意义的高科技部门提供直接利益。将作出额外努力，征聘妇女和其他人数不足的群体担任这个项目的研究助理，让太平洋岛民少数群体的代表担任本科研究人员，并作为外联努力的一部分向高中学生伸出援手。
