Characterization of Disk/Head Interfacial Contacts Through System Dynamics and Microelectromechanical Sensors

9800180 Shen A GOALI奖支持对磁存储系统中微型读/写磁头与移动磁盘滑动接触时行为的合作研究。该项目涉及设计和制造用于监测接触的微机电力和应变传感器，开发严格的滑块模型和适当的算法，以便根据实验结果重建接触力，并进行现场测试以验证模型和算法。在这项合作研究中，密歇根大学将主要负责传感器的开发，华盛顿大学负责模型和算法的开发，希捷科技公司将帮助校准传感器并进行现场测试。* * *

9800180 Shen A GOALI award supports a collaborative study of the behavior of pico read/write heads in magnetic storage systems as they are in gliding contact with the moving disk. The project involves design and fabrication of micro-electromechanical force and strain sensors to monitor the contacts, development of a rigorous slider model and suitable algorithms that allow reconstruction of contact forces from experimental results, and the conduct of field tests for validation of the model and the algorithms. In this collaborative study, the University of Michigan will be primarily responsible for the sensor development, the University of Washington for development of model and algorithms, and Seagate Technology Corporation will help calibrate the sensors and conduct the field tests. ***
