Abstract
A head has an air bearing surface with left and right leading pressurizing steps. The left and right leading pressurizing steps are each partially surrounded by left and right leading pads, respectively. The left leading pressurizing step includes a left short region that extends for a first distance (measured parallel to the slider longitudinal axis) from the leading face of the slider to the left leading pad. The left leading pressurizing step also includes a left long region that extends for a second distance (measured parallel to the longitudinal axis) from the leading face to the left leading pad. The second distance is at least 25% greater than the first distance. The left short region is disposed closer to the left lateral face than is the left long region. The left long region is disposed closer to the longitudinal axis than is the left short region.
