Abstract:
1. A head slider, comprising: a disk-facing surface having an inflow end to which air flows in and an outflow end from which air flows out; an inflow-end-side rail situated on the disk-facing surface and extending along the inflow end; a negative pressure part situated on the disk-facing surface closer to the outflow end than the inflow-end-side rail, the negative pressure part developing a negative pressure while in use; and two or more extension rails of constant width situated on the disk-facing surface and extending in the negative pressure part from the inflow end to the outflow end; and an inflow-end-side-positive-pressure part situated further towards the outflow end than the inflow-end-side rail and further towards the inflow end than the extension rails, the inflow-end-side-positive-pressure part developing a positive pressure while in use, wherein said two or more extension rails are arranged along parallel straight lines and extend in a direction perpendicular to a width direction, and wherein the inflow-end-side-positive-pressure part extends in the width direction along the inflow-end-side rail and in contact with the inflow-end side rail, and at least one of the end parts on the inflow end side of the extension rails is in contact with the inflow-end-side-positive-pressure part.
