ABSTRACT:
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; anda 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.
