Magnetic Recording Research

我们打算在未来十年内为实现高数据速率大容量存储系统的密度接近每平方英寸109位做出重大贡献。我们将重点放在增加纵向和垂直磁记录轨道密度的原理和技术上，暂定目标是每英寸104转。这项工作的重点将在磁学方面，并将涉及研究电感和磁阻记录磁头的边缘读写特性以及薄膜介质的边缘定义。这项工作将由华盛顿大学和惠普实验室合作进行。根据目前国家科学基金会支持的合作的经验，共同制定了要承担的个别任务。这种协作产生了适合所提议工作的工具，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WU，媒体和设备的制造，实验设施和大规模计算将由惠普实验室为WU的首席研究员和研究生以及直接参与工作的惠普工程师和科学家提供。

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.
