Abstract
A disk drive for redirecting contaminating particulate matter away from an area bearing of a slider element. At least two etched channels are provided in the slider element of the disk drive. The at least two etched channels direct incoming air flow to a leading edge of the slider element from the leading edge towards respective sides of the slider element. Particulate matter that may be progressing towards the air bearing are redirected by virtue of the incoming air flow to the leading edge and expelled from the air bearing via the at least two etched channels.
