We intend to make a strong contribution toward the achievement of a density approaching 109 bits per square inch in high data rate mass storage systems within the next decade. We are placing primary emphasis on principles and techniques that will permit the increase of track density in longitudinal and perpendicular magnetic recording, with a provisional goal of order 104 turns per inch. The thrust of the work will be in magnetics, and will involve studies of the edge- reading and writing properties of inductive and magnetoresistive recording heads and of the edge definition of thin film media. The work will be carried out as a collaboration between Washington University and Hewlett-Packard Laboratories. The individual tasks to be undertaken have been formulated jointly, based on the experience of the current NSF supported collaboration. This collaboration is producing tools appropriate for the proposed work, and has resulted in a more sharply focused approach. Theoretical work and interpretation of experimental results will be concentrated at WU, fabrication of media and devices, experimental facilities, and large scale computation will be provided by HP labs for the WU principal investigator and graduate students and for the HP engineers and scientists directly participating in the work.

我们打算在未来十年内为在高数据速率海量存储系统中实现接近 109 位/平方英寸的密度做出巨大贡献。 我们主要强调能够增加纵向和垂直磁记录磁道密度的原理和技术，临时目标是每英寸 104 匝。 这项工作的重点是磁学，并将涉及感应和磁阻记录头的边缘读取和写入特性以及薄膜介质的边缘定义的研究。 这项工作将由华盛顿大学和惠普实验室合作进行。 根据当前 NSF 支持的合作经验，共同制定了要承担的各项任务。 这种合作正在生产适合拟议工作的工具，并产生了更加集中的方法。 理论工作和实验结果的解释将集中在西伯利亚大学，介质和设备的制造、实验设施和大规模计算将由惠普实验室为西伯利亚大学的首席研究员和研究生以及直接参与这项工作的惠普工程师和科学家提供。
