Abstract
A slider that minimizes lubricant accumulation includes bearing surfaces that provide above ambient fluid pressure, a cavity located between two bearing surfaces and at least one step feature that is spaced apart from the bearing surfaces and is located in and protrudes from a floor of the cavity at a height that is less than a height of the bearing surfaces. The at least one step feature includes surfaces configured to diverge and converge airflow in the cavity.
