A Systematic Study of Overcoat-Lubricant Interfaces Used in Magnetic Recording Media

GOALI项目是由分析和表面化学项目以及多学科活动办公室支持的。它聚焦于斯坦福大学和IBM Almaden研究中心在一个极其重要的问题上的合作，即提高磁记录介质的耐用性和面密度。Klug教授和他在斯坦福大学的学生将与IBM Almaden的Wade和Sherwood博士密切合作，利用表面光谱和固态核磁共振光谱系统地研究硬盘的涂层-润滑剂界面。溶胶-凝胶二氧化硅和由全氟聚醚组成的无定形碳上的涂层将是本研究的重点。这个项目将改善磁记录设备的技术，这个高风险-高回报的项目将提升学生的教育体验。学生将在工业环境中获得广泛的经验，从基本的实验室工作到在制造设施中的实施。许多工业科学家对这些学生的指导对他们做出职业决策将是无价的。Klug教授和他在斯坦福大学的学生将与IBM Almaden研究中心的Wade和Sherwood博士合作，开展与行业学术联系的赠款机会项目，研究磁记录材料的表面。通过系统地研究这些表面的润滑性能，将开发出具有更大的数据存储容量和更好的耐用性的计算机硬盘。固体核磁共振波谱将是研究这些表面的主要方法，在这项工作中需要特别注意这些薄膜材料的处理，以便获得有用的信息。Klug教授和他的学生将在这个项目中通过与他们的IBM工业合作伙伴合作获得宝贵的经验。在这些学生做出未来的职业决策时，工业科学家对他们的指导将是无价的。

This Grant Opportunities for Academic Liaison with Industry (GOALI) project is supported in the Analytical and Surface Chemistry Program and the Office of Multidisciplinary Activities. It focusses on collaboration between Stanford University and IBM Almaden Research Center on an extremely important problem, increasing the durability and areal density of magnetic recording media. Professor Klug and his students at Stanford University will work in close collaboration with Drs. Wade and Sherwood at IBM Almaden to systematically study the overcoat-lubricant interface of hard disks using surface spectroscopy and solid-state Nuclear Magnetic Resonance Spectroscopy. Overcoats on sol-gel silicon dioxide and on amorphous carbon composed of perfluoro-polyethers will be the focus of this study. The technology of magnetic recording devices will be improved by this project and this high risk-high return project will enhance the educational experience of students. The students will gain broad experience in an industrial setting ranging from basic laboratory work to implementation in a manufacturing facility. The mentoring of these students by many industrial scientists will be invaluable to them as they make career decisions. Professor Klug and his students at Stanford University will collaborate with Drs. Wade and Sherwood at IBM Almaden Research Center in the Grant Opportunities for Academic Liaison with Industry project to study the surfaces of magnetic recording materials. Through a systematic study of the lubrication properties of these surfaces computer hard disks will be developed that have increased data storage capacities and improved durability. Solid-state Nuclear Magnetic Resonance Spectroscopy will be the central method used to study these surfaces and special attention to handling of these thin film materials will be required in this work in order to obtain useful information. Professor Klug and his students will gain valuable experience through collaboration with their IBM industrial partners during this project. Mentoring of these students by industrial scientists will be invaluable as they make future career decisions.
