The objective in this research is to demonstrate electrochemically fabricated magnetic bit-patterned media using precision fabricated templates to achieve data storage densities above ten terabit per square inch, far surpassing what is available in today?s even most advanced magnetic data storage systems.The intellectual merit of the proposed multifaceted research is to contribute to the understanding of the materials science and engineering of underpotential codeposition of magnetic alloys, the potential of self-limiting ion milling for ultrahigh density square matrix template nanofabrication, and the effects of spatial confinement on face-centered-cubic to face-centered-tetragonal phase transformation kinetics in ultrahigh anisotropy iron-platinum materials system. The availability of ultrahigh magnetic anisotropy nanostructured arrays that will be developed in the course of this project will further facilitate the fundamental studies of the scalability limits of magnetic recording.The broader impact of this research is to enable a range of transformative data-storage applications such as probe-based data storage, in which two-dimensional arrays of read/write nanotransducers are used to address the bits on patterned media. Extremely high data storage bit densities to be explored in the course of this project will be sufficient, for example, to serve all the data storage needs of the world?s largest corporation with a single desktop computer! The proposed program will be integrated with existing NSF-REU, RET, and NUE programs as well as State-supported programs, in which the investigators actively participate, to enhance the recruitment of women and underrepresented minorities into the fields of science and engineering.

在这项研究中的目标是证明电化学制造的磁性位图案化的媒体，使用精密制造的模板，以实现数据存储密度超过每平方英寸10太比特，远远超过了今天可用的？所提出的多方面研究的智力价值是有助于理解磁性合金的欠电位共沉积的材料科学和工程，自限制离子铣削用于高密度正方形矩阵模板纳米纤维的潜力，以及空间约束对铁-铂材料体系面心立方-四面体相变动力学的影响。在本项目过程中开发的磁各向异性纳米结构阵列的可用性将进一步促进对磁记录可扩展性限制的基础研究，这项研究的更广泛影响是使一系列变革性的数据存储应用成为可能，例如基于探针的数据存储，其中使用读/写纳米传感器的二维阵列来寻址图案化介质上的位。例如，在本项目过程中探索的极高数据存储位密度将足以满足世界上所有的数据存储需求。它是拥有一台台式电脑的最大的公司！拟议的计划将与现有的NSF-REU，RET和NUE计划以及国家支持的计划相结合，调查人员积极参与，以加强妇女和代表性不足的少数民族的招聘进入科学和工程领域。
