The award funds a non-contacting profilometer to be used in on-going research on the wear behavior of solid lubricant films on oxide coated disks used for magnetic information storage. These lubricant films prevent head "crashes" and consequent information loss during start-up or power loss. Since they cannot be replenished during the life of the hard disk their wear behavior is critical to the over-all performance of the disk; and since they are extremely thin and easily deformed their wear behavior is most readily studied using a high-resolution, non-contacting optical profilometer such as the instrument funded under this grant.

该奖项资助了一种非接触式轮廓仪，用于正在进行的磁性信息存储氧化物涂层磁盘上固体润滑膜磨损行为的研究。 这些润滑膜可防止磁头在启动或断电期间发生“碰撞”并导致信息丢失。 由于它们在硬盘的使用寿命期间无法补充，因此它们的磨损行为对于磁盘的整体性能至关重要； 由于它们非常薄且容易变形，因此最容易使用高分辨率、非接触式光学轮廓仪（例如本次拨款资助的仪器）来研究它们的磨损行为。
