respect to slider 32 with portions of the slider 32 u2032 hatched to represent surfaces at different heights for clarity however as illustrated in fig3 a sacrificial layer of material 62 u2032 is applied to recesses 58 u2032 and 60 u2032 in two discrete rectangular areas that each covers a portion of the protrusion 52 near corners of the slider body 38 at the leading edge 40 bottom surfaces of the sacrificial layer of material 62 u2032 lie substantially within a single plane with surfaces of the protrusions 48 and 50 as well as bottom surface portions of the protrusion 52 located adjacent to u2014 but not covered by u2014 the sacrificial layer of material 62 u2032 in order to collectively define the abs by locating the sacrificial layer of material 62 u2032 in discrete areas at corners of the slider 32 u2032 the sacrificial layer of material 62 u2032 is positioned in locations most likely to contact the storage medium 22 during extreme roll static attitude rsa and pitch static attitude psa conditions while reducing a total amount of the sacrificial material utilized fig4 is a flow chart illustrating a method of manufacturing a slider initially an abs is formed on a slider body step 100 the abs can be formed using conventional techniques such as photolithography and milling ceramic material e g alotic of the slider body to.
