The present invention is directed to a load/unload disk drive that
includes: a rotational arm engaging a slider; a magnetic storage disk,
wherein the magnetic head in the slider reads data from and/or writes
data to a data zone of the magnetic storage disk; and a ramp positioned
next to the magnetic storage disk. The magnetic storage disk includes a
slider cleaning zone having a roughness greater than a roughness of the
data zone. The slider is periodically contacted with the slider cleaning
zone to remove particles collected on the slider.
