Abstract
A disc head slider (36) includes a slider body with leading, trailing, inside and outside slider edges (50,52,54,56) and a slider center line (58) extending from the leading slider edge (50) to the trailing slider edge (52). First and second raised side rails (60,62) are formed in the slider body and each include an inside rail edge (108), an outside rail edge (110), a leading rail edge (50) and a trailing rail edge (112). The first and second raised side rails (60,62) form first and second bearing surfaces (70,72), respectively, which terminate prior to the trailing slider edge (52). A raised center rail (64) extends along the slider center line (58) and between the first and second raised rails (60,62). First and second cavities (80a,80b) are positioned between the raised center rail (64) and the first and second raised rails (60,62), respectively. The first and second bearing surfaces (70,72) each include a leading section (100), a waist section (104), a leg section (102) which extends from the waist section (104) to the leading section (100), and a trailing section (106) which extends from the waist section (104) to the trailing rail edge (112). The trailing section (106) widen…
