RIA: The Role of Lubricant Viscosity in the Frictional Behavior of the Magnetic Slider/Disk

研究启动奖将支持对磁记忆存储硬盘上润滑剂薄膜行为的研究。各种聚氟聚醚薄膜将被应用于有碳涂层的圆盘。将监测各种速度和负载条件下的磁头-磁盘摩擦，并使用自动椭偏仪测量润滑膜的逐渐变薄。建立了润滑剂粘度对其作为薄膜润滑剂性能影响的模型。

A Research Initiation Award will support research on the behavior of thin films of lubricants on magnetic memory storage hard disks. Thin films of various polyfluoropolyether will be applied to disks with carbon overcoats. The head-disk friction will be monitored for various conditions of speed and load and the gradual thinning of the lubricant film will be measured using automatic ellipsometry. A model will be developed for the effect of a lubricant's viscosity on its performance as a thin-film lubricant.
