Head slider, magnetic storage apparatus and head slider producing method

摘要

A head slider has a medium opposing surface configured to confront and float from a surface of a recording medium. A front rail is disposed on the medium opposing surface in a vicinity of an air inlet end and has a first air bearing surface and a first step surface which forms a stepped portion with the first air bearing surface which is higher than the first step surface relative to the medium opposing surface. A rear rail is disposed on the medium opposing surface in a vicinity of an air outlet end and has a second air bearing surface and a second step surface which forms a stepped portion with the second air bearing surface which is higher than the second step surface relative to the medium opposing surface. The first air bearing surface is substantially surrounded by the first step surface.
