Patent ID: 7978436

Claim:
A slider for use in a disk drive comprising: an air bearing surface; an air channel and a pocket formed in said air bearing surface and laterally disposed to either side of a first long rail, wherein said first long rail contacts a center pad leading edge and runs medially therefrom in a direction from said center pad leading edge towards a leading edge of said slider forming a common boundary of said air channel and said pocket, whereby said air channel is isolated from said pocket; wherein said pocket is closed at said leading edge of said center pad by an angled trapper connecting said first long rail to a short rail, that is shorter than said first long rail and is parallel to said first long rail and contacts said center pad and wherein said air channel is formed by said first long rail and a second long rail, also originating at said leading edge of said center pad and of substantially equal length as said first long rail and parallel to said first long rail on an opposite side of said first long rail as said short rail, whereby said channel is closed by said leading edge of said center pad and wherein said air channel has an asymmetric opening facing said leading edge of said slider wherein said asymmetry is caused by a partial deflector formed in said first long rail of said air channel boundary wherein said partial deflector makes a deflect angle with respect to said first long rail by bending away from said second long rail, whereby a variation of direction and amount of airflow into said closed air channel and into said closed pocket provides a controllable aerodynamic lift force on said air bearing surface.
