Patent ID: 8184405

Claim:
A slider, comprising: A backside surface whereby said slider attaches to a suspension; an ABS side, having a leading edge and a trailing edge wherein said leading edge and said trailing edge have a common width which is the slider width and wherein the slider length is the longitudinal distance between said leading edge and said trailing edge, wherein said ABS side has a variable depth topography and faces a surface of a rotatable disk; a leading edge portion and a trailing edge portion, wherein said portions are separated by a transverse deep air groove; a center pad containing an embedded transducer formed in said trailing edge portion; a transversely directed cross-track channel formed in said leading edge portion; a centrally positioned down-track channel extending between said trailing edge portion and said leading edge portion, wherein said down-track channel has a leading edge end and a trailing edge end and a longitudinal periphery formed by separated longitudinal edges directed longitudinally along a central axis, wherein said longitudinally directed edges of said channel are of equal height within said trailing edge portion but are of unequal height where they bisect said deep air groove and form a dual-height bridge that bisects said deep air groove and terminates to form a kink/bar, junction with said cross-track channel and forming, thereby, a T-shaped airflow channeling structure, and wherein said trailing edge end of said down-track channel abuts said center pad; a first pair of air pockets formed in said trailing edge portion to either side of said down-track channel; a second pair of air pockets formed in said leading edge portion to either side of said cross-track channel; a closed shallow dam along said trailing edge forming a trailing edge boundary of said first pair of air pockets and closing off outflows of air from said first pair of air pockets.
