Abstract

An apparatus and associated method employing a slider having a leading edge opposing a trailing edge. A fluid bearing surface extends between the leading edge and the trailing edge. The fluid bearing surface contactingly engages a fluid stream operably imparted to the fluid bearing surface by a moving member adjacent thereto. A trailing edge pad extends from the fluid bearing surface adjacent the trailing edge. A capillary lubrication trench (CLT) is disposed entirely between a portion of the trailing edge pad and the trailing edge along a direction that is parallel to a longitudinal axis from the leading edge to the trailing edge.
