Abstract

Stiction and durability problems associated with magnetic storage systems can be eliminated by a technology known as Load/Unload. In this system, the slider is designed never to touch the disk surface. When the drive is not in operation, the slider carrying suspension rests on top of a ramp so that the slider is fully off the disk surface.

Pre-Conditioning of Sliders to Minimize Disk Damage during Load/Unload

      Stiction and durability problems associated with magnetic
storage systems can be eliminated by a technology known as
Load/Unload.  In this system, the slider is designed never to touch
the disk surface.  When the drive is not in operation, the slider
carrying suspension rests on top of a ramp so that the slider is
fully off the disk surface.

      During the start phase, the suspension moves off the ramp and
the slider loads onto the disk surface while the disk is spinning at
some designed speed.  One potential problem with this type of system
is disk damage due to head/disk contacts during loading and unloading
processes.

      By burnishing or pre-conditioning the sliders, the likelihood
of disk damage can be minimized.  The burnishing or pre-conditioning
process should remove any sharp protrusions and round sharp corners
so as to significantly reduce the stress imparted on to the disk by
the slider.
