Micromotion release of heads from lubricated magnetic disks

摘要

In a magnetic recording disk file in which one or more magnetic sliders rest on the surfaces of the disks when the disks are not rotating, a short oscillatory micromotion is imparted to the slider or sliders prior to starting rotation of the disks, this micromotion serving to free the slider or sliders from any stiction forces tending to bind them to the disk surface.
