Abstract:
A head slider having an air inlet end, an air outlet end, an inner side, an outer side, and a disk opposing surface configured to be opposed to a disk, wherein when said head slider is in its operative position, said inner side faces radially inwardly of the disk and said outer side faces radially outwardly of the disk, said head slider comprising:an inner rail formed on said disk opposing surface so as to extend substantially from said air inlet end to said air outlet end, said inner rail having a generally flat air bearing surface for generating a flying force during rotation of said disk, said inner rail comprising a first air inlet end portion, a first air outlet end portion, and a first intermediate portion connecting said first air inlet end portion and said first air outlet end portion;an outer rail formed on said disk opposing surface in spaced relationship from said inner rail so as to extend substantially from said air inlet end to said air outlet end, said outer rail having a generally flat air bearing surface for generating a flying force during rotation of said disk, said outer rail comprising a second air inlet end portion, a second air outlet end portion, and a second intermediate portion connecting said second air inlet end portion and said second air outlet end portion; anda groove defined between said inner rail and said outer rail for expanding air once compressed to generate a negative pressure;wherein a longitudinal center line of said first intermediate portion of said inner rail and a longitudinal center line of said second intermediate portion of said outer rail are inclined at a given angle with respect to a longitudinal center line of said slider so that end portions of said first and second intermediate portions on the side of said air inlet end are nearer to said inner side of said head slider;and further wherein longitudinal center lines of portions of said inner and outer rails other than said first and second intermediate portions are not inclined at said given angle, whereby said longitudinal center lines of said first and second intermediate portions of said inner and outer rails are the only longitudinal center lines of said inner and outer rails inclined at said given angle.
