Magnetic Recording Research

华盛顿大学和惠普公司将参与一个为期两年的合作实验和理论研究项目，涉及将微磁学应用于磁性和磁光记录的问题领域。研究领域的定义取决于对需求的认识、主要工业实验室的实验和计算资源，以及学术首席研究员（该学科的创始人之一）对进步机会的认识。提出的研究将加深对磁性和磁光写入和读出过程的理解。一项研究将为改进磁读出频率响应的解释提供基础。主要研究方向为纵向钴合金薄膜介质的优化设计，以及提高对双层垂直高密度记录介质的理解和控制。另一项研究涉及使用分析和数值微磁计算相结合的Cr0介质的现实建模。一项理论研究将检查热磁光激光写入过程的细节。

Washington University and Hewlett-Packard will engage in a cooperative two year program of experimental and theoretical studies involving applications of micromagnetics to problem areas in magnetic and magneto-optic recording. The study areas are defined by the recognition of needs and by the experimental and computing resources of a major industrial laboratory, and by the awareness of opportunities for progress on the part of an academic principal investigator, one of the founders of the discipline. The proposed studies will deepen the understanding of the magnetic and magneto-optic write and readout processes. One study will provide a basis for improvements in the interpretation of the frequency response of magnetic readout. Two major investigations are directed at optimizing the design of longitudinal cobalt alloy thin film media, and at improving the understanding and control of double-layer perpendicular high density recording media. Another study is concerned with the realistic modeling of Cr0 patriculate media, using a combination of analytical and numerical micromagnetic calculations. One theoretical study will examine the details of the thermal magneto-optic laser write process.
