Collaborative Research: Dynamic Mode, High Density, Probe Based Data Storage

目的：对于存储和访问大量数据且易于便携的需求从小形状因子消费电子产品的普遍使用中显而易见，其中预测了对每平方英寸兆兆比特面密度的需求。传统的数据存储模式正在达到可实现的面密度的基本限制。基于原子力显微镜原理的基于探针的数据存储解决方案采用具有原子尺度图像数据分辨率的力探针。信息以几平方纳米的压痕形式存储。基于探针的高密度数据存储有希望在短期内提供每平方英寸几兆比特的密度。动态模式探头为基础的数据存储平台将根据建议的目标。智力优点：探头动态的实时模型将开发高密度数据存储应用。的动态模式操作，导致显着更小的力量对媒体和探头将采用相比，静态模式操作，已在以前的工作中使用。克服了当前动态模式中存在的阅读数据的速度和读取数据的分辨率之间的基本折衷，导致检测速度的两个数量级增加。该提案的物理建模部分将提供探头和介质之间出现的力的适当抽象级别，该抽象级别仍然易于处理，并且足以用于数据存储目的。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信道模型。更广泛的影响：该提案的目标如果实现，将直接影响消费电子市场，并将提供一种小型高密度数据存储替代方案。通过学生互访和举办专门讲习班，将实现学术界和工业界之间知识的协同转移。将开发一门关于基于探测器的数据存储的新课程，该课程将系统和物理社区之间的知识联系起来。

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 delivering a 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 tosignificantly 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 remains tractable and is sufficient for data storage purposes. The communication system modelling and design objectives part will develop a communication channel model of the data storage system. Efficient and high performance detectors and error control codeswill 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 know how 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 between the systems and physics communities will be developed.
