  • Air-bearing surface (ABS) design to reduce particle scratch risk
    Patent number: 11114121
    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.
    Type: Grant
    Filed: October 19, 2020
    Date of Patent: September 7, 2021
    Assignees: SAE Magnetics (H.K.) Ltd., Headway Technologies, Inc.
