Air bearing surface design with extreme particle trapping holes for improving HDD particle robustnes

摘要

Embodiments disclosed herein generally relate to a head slider within disk drive data storage devices. A head slider comprises a head body having a leading portion on a leading edge and a trailing portion on a trailing edge. The leading portion includes a first leading pad disposed at the MFS and a second leading pad disposed between the first leading pad and the leading edge. The second leading pad is recessed a first vertical distance from the MFS. One or more particle trapping holes are disposed between the first leading pad and the second leading pad. The one or more particle trapping holes are recessed a second vertical distance from the MFS, the second vertical distance being greater than the first vertical distance. Particles encountered by the leading portion may be suctioned into the one or more particle trapping holes, preventing the particles from building-up onto the MFS.
