Objective: The need for storing and accessing large amounts of data with the ease of being portable is apparent from the ubiquitous use of small form factor consumer electronics where demands for terabit per inch square areal densities is predicted. Conventional modes of data storage are reaching fundamental limitations on the areal densities achievable. Probe based data storage solutions, based on atomic force microscopy principles employ a force probe that has the resolution to image data at the atomic scale. Information is stored in the form of indentations that are a few square nanometers in area. Probe based high density data storage has the promise of deliveringa few terabit per square inch densities in the near term. The dynamic mode probe based data storage platform will be developed under the proposal goals.Intellectual Merit: A real-time model of the probe dynamics will be developed for high density data storage applications. The dynamic mode operation that leads to significantly smaller forces on the media and the probe will be employed as compared to the static mode operation that has been used in previous work. The fundamental tradeoff between the speed of reading the data and the resolution of the read data existing in current dynamic modes is overcome, leading to two orders increase in the detection speed. The physical modelling part of the proposal will provide an appropriate level abstraction of the forces appearing between the probe and media that remainstractable and is sufficient for data storage purposes. The communication systemmodelling and design objectives part will develop a communication channel model of the data storage system. Efficient and high performance detectors and error control codes will be developed for the system.Broader impacts: The proposal objectives if achieved will directly impact theconsumer electronics market and will provide a small form factor high density data storage alternative. Synergistic transfer of knowhow between the academia and industry by exchanging student visits and presenting specialized workshops will be achieved. A new course on probe based data storage that bridges the know how.

目的：从无处不在的小型消费电子电子产品的使用中，可以清楚地可以存储和访问大量数据并易于便携，从而可以预测对每英寸平方平方平方英尺密度的需求。传统的数据存储模式正在达到可实现的面积密度的基本限制。基于探针的数据存储解决方案，基于原子力显微镜原理采用了一种力探针，该探针具有分辨率以原子量表图像数据的分辨率。信息以凹痕形式存储，这些压痕是区域中一些平方纳米的。基于探针的高密度数据存储有望在短期内传递每平方英寸密度的几吨。基于动态探针的数据存储平台将在提案目标下开发。智能优点：将针对高密度数据存储应用程序开发探针动力学的实时模型。与先前工作中使用的静态模式操作相比，将采用导致介质和探测器上明显较小的力和探针的动态模式操作。克服了当前动态模式中存在的读取数据的速度与分辨率的分辨率之间的基本权衡，从而导致检测速度增加了两种订单。该提案的物理建模部分将提供适当的探测器和培养基之间出现的力的抽象，以保持可提取，并且足以满足数据存储目的。通信系统建模和设计目标部分将开发数据存储系统的通信渠道模型。将为系统开发高效和高性能检测器和错误控制代码。Broader的影响：提案目标如果达到的目标将直接影响tecmosumer电子产品市场，并将提供较小的外形高密度数据存储替代方案。通过交换学生的访问并展示专门的讲习班，学术界和行业之间的知识转移。基于探针的数据存储的新课程，桥接了知识。
