Abstract
A disk drive is provided having one or more structural air bearing surface (ABS) features that can block particulate matter, such as lube droplets that may enter the air bearing from the trailing edge or rearward portion of the slider. Moreover, such structural ABS features can influence air flow within or about the air bearing to prevent or at least reduce the accumulation of particles and/or droplets in one or more areas of the air bearing to reduce the reliability problems induced by particle contamination and lube pick-up.
