Patent 5,917,679
at least one of said first rear termination and said second
rear termination not coinciding with said rear edge, and being
disposed upstream of said rear edge relative to said rotational
direction of said recording medium.
31. A negative pressure air bearing slider, comprising:
a principal surface defining a first plane tangential to a
first direction;
said principal surface having a lead portion and a rear
portion, said lead portion being spaced upstream from said rear
portion relative to said first direction, said lead portion having a
front edge, said rear portion having a rear edge, said front edge
and said rear edge together defining longitudinal boundaries of
said principal surface in said first direction; and
a U-shaped air bearing platform having a plurality of air
bearing surfaces surrounding a negative pressure cavity while
defining a second plane tangential to said first direction, said
U-shaped air bearing platform comprising not more than two
separate air bearing platforms each extending from said lead
portion rearwardly toward said rear portion and respectively
terminating at a first rear termination and a second rear
termination, at least one of said not more than two separate air
bearing platforms including a side wall portion;
at least one of a surface between said first rear
termination and said rear edge and a surface between said
second rear termination and said rear edge being in said first
plane.
42. A negative pressure air bearing slider, comprising:
a slider having a body with a principal surface disposed
to confront a recording surface of a recording medium, said
principal surface having a lead portion and a rear portion, said
lead portion being spaced upstream from said rear portion
relative to a rotational direction of any recording medium
confronted by said slider with a longitudinal axis of said slider
