Abstract:
A slider design for a hard disk drive (HDD) features a shallow cavity adjacent to a leading edge that has patterns of sub-cavities of various shapes etched into its base to reduce its original surface area. The presence of these patterns of sub-cavities significantly reduces the probability that the slider will capture particles on the surface of a rotating disk and thereby reduces the corresponding probability of surface scratches that such captured particles inevitably produce.

Claim (Index 9):
A method to reduce surface scratching of a disk during hard disk drive (HDD) operation comprising:\n providing said HDD with an operational slider having a body of substantially rectangular horizontal cross-section, wherein said slider has a leading edge (LE), a trailing edge (TE) parallel to said leading edge and parallel sides extending from said leading edge to said trailing edge to define a rectangular periphery of said horizontal cross-section and an upper surface defining an air-bearing surface (ABS); wherein said slider further includes a multiplicity of cavities formed in said slider body, wherein said cavities are formed with substantially planar bases at different depths relative to said ABS and wherein said cavities include a cavity of minimal depth and approximately rectangular horizontal cross-section formed immediately adjacent to and parallel to said leading edge and extending transversely across said slider ABS; wherein said cavity of minimal depth includes a pattern of sub-cavities formed therein, the sub-cavities having various cross-sectional shapes and areas and etched, with various depths, into said planar base; whereby the presence of said pattern of sub-cavities reduces the total base area of said cavity of minimal depth and thereby reduces the probability of trapping particles on the surface of a rotating disk operationally positioned adjacent to said slider and thereby eliminates the problem of scratching said disk surface.
