Abstract
A slider for supporting a transducing head proximate to a rotating disc. The slider has a slider body having a disc opposing face and a longitudinal axis. The disc opposing face is bounded by a leading edge, a trailing edge, and first and second side edges. An air bearing surface is defined on the disc opposing face with the air bearing surface having at least one pad located behind the leading edge. A cavity is positioned on the disc opposing face and the cavity is recessed from the air bearing surface at a cavity depth. At least a portion of the cavity precedes the pad. A funnel directs airflow within the cavity from the leading edge to the pad.
