Abstract
A slider is used for supporting a transducing head proximate a rotating disc. The slider includes a slider body having a disc opposing face bounded by a leading edge, a trailing edge, and first and second side edges. The slider body has a longitudinal axis. An air bearing surface is defined on the disc opposing face and the air bearing surface has a pad proximate the trailing edge. A trench is positioned adjacent to the pad with the trench being recessed from the air bearing surface at a step depth. A channel for flushing lubricant from the disc opposing face is positioned on the pad. The channel is recessed from the air bearing surface at a channel depth.
Claims18
A slider comprising:
- a slider body which includes an air bearing surface bounded by a leading edge and a trailing edge, the air bearing surface having a pad proximate the trailing edge, and a trench positioned adjacent to the pad with the trench being recessed from the air bearing surface at a step depth;
- and means for flushing lubricant accumulated in the trench from the slider body.
A slider comprising:
- a slider body having an air bearing surface bounded by a leading edge, a trailing edge, and first and second side edges, the slider body having a longitudinal axis;
- a pad proximate the trailing edge on the air bearing surface;
- a trench positioned adjacent to the pad, the trench being recessed from the air bearing surface at a step depth;
- and
- a channel for flushing lubricant from the air bearing surface, the channel positioned on the pad and having a first end and a second end, the first end connected to the trench and the second end lying adjacent an outer edge of the pad proximate the trailing edge, wherein the channel is recessed from the air bearing surface at a channel depth.
A slider comprising:
- a slider body having an air bearing surface bounded by a leading edge, a trailing edge, and first and second side edges, the slider body having a longitudinal axis;
- a pad proximate the trailing edge on the air bearing surface;
- a cross rail positioned along the leading edge and extending from the first side edge to the second side edge wherein the cross rail has a height equal to the air bearing surface;
- first and second side rails positioned substantially along the first and second side edges;
- a cavity positioned on the air bearing surface, wherein the cavity is at a cavity depth recessed from the air bearing surface, at least a portion of the cavity preceding the pad;
- a trench positioned adjacent to the pad, the trench being recessed from the air hearing surface at a step depth;
- and
- a channel for flushing lubricant from the air bearing surface, the channel positioned on the pad and having a first end and a second end, the first end connected to the trench and the second end lying adjacent an outer edge of the pad proximate the trailing edge, wherein the channel is recessed from the air bearing surface at a channel depth.
