Appeal No. 2003-1173
Application No. 09/991,855
BACKGROUND
The invention is directed to a slider for magnetic recording heads. According to
appellants, the slider is shaped to minimize debris accumulation in its magnetic
recording environment. Representative claims 5 and 70 are reproduced below.
5. A slider for supporting a magnetic transducer above the surface of a
rotating disk medium, said slider comprising:
a body;
a plurality of rail members extending outward from said body in a direction
towards said medium, each of said rail members having a leading and a trailing
edge with said leading edge facing in the general direction of relative motion
between said transducer and said medium, and wherein said leading edge has a
narrower width as compared to said trailing edge, extends to said body, is
spaced from outer side surfaces of said body, and is not part of a flat surface;
each of said rail members also having an air-bearing surface which is
alternately brought into contact with and separated from said surface of said
medium, said air-bearing surface being generally parallel to said surface of said
medium.
70. A slider comprising:
a transducer for transferring information to and from a rotating disk
medium during read and write operations; and
first and second rails, wherein each of the rails has a leading edge that
faces into a general direction of relative motion between the slider and the
medium, a trailing edge that faces away from the direction, and an air-bearing
surface, the leading edge has a width that is substantially perpendicular to the
direction, the trailing edge has a width that is substantially perpendicular to the
direction, and the width of the leading edge is substantially narrower than the
width of the trailing edge, each of the rails includes a V-shaped portion, a narrow
part of the V-shaped portion is the leading edge and a wide part of the V-shaped
portion is the trailing edge.
