摘要：
We report experimental data that suggest the existence of a critical clearance between the flying head and the disk in a hard disk drive, below which significant lubricant transfer from the disk to the slider takes place. This phenomenon is interpreted as originating from dewetting instabilities brought about by molecular interactions with the slider. A model that reproduces the onset of instability is presented.
