Patent ID: 7355814

Claim:
A load/unload disk drive, comprising: a rotational arm engaging a slider, the slider comprising a magnetic head, wherein the magnetic head has a range of rotation and wherein the range of rotation covers a radial extent of the disk; a magnetic storage disk, wherein the magnetic head is operable to read data from and/or write data to a data zone of the magnetic storage disk, the data zone being in the radial extent of the disk; and a ramp positioned next to the magnetic storage disk, wherein, in a first operational mode, a portion of the rotational arm movably engages the ramp and, in a second operational mode, the rotational arm rotates independently of the ramp, wherein the magnetic storage disk comprises a slider cleaning zone located in the radial extent of the disk, the slider cleaning zone having a roughness greater than a roughness of the data zone, whereby at least a portion of the slider is contacted with the slider cleaning zone to remove particles collected on the slider, and wherein the slider cleaning zone comprises a plurality of raised subregions, each of the subregions being elevated relative to the data zone of the disk, and wherein a center-to-center spacing between at least most of the adjacent subregions ranges from about 5 to about 50 microns.
