Abstract
An apparatus and associated method for a slider pad that allows for contact to be mitigated without plastic deformation. Various embodiments of the present invention are generally directed to a slider that presents a transducer and has at least one air bearing surface (ABS) feature. The ABS feature comprises a pair of sidewalls spaced a distance X apart. A pad is deposited on the ABS feature so that the pad comprises a hemispherical cross-section and has a circumferential diameter greater than X.
Claims20
An apparatus comprising:
- a slider presenting a transducer, wherein the slider has at least one air bearing surface (ABS) feature comprising a pair of sidewalls spaced apart and each having a width X;
- and
- a pad deposited with the width X on the ABS feature, wherein the pad comprises a hemispherical cross-section and has a circumferential diameter greater than width X, the pad capable of mitigating contact between the pad and a media surface with elastic deformation.
A data storage device comprising:
- a slider presenting at least one transducer, wherein the slider has at least one air bearing surface (ABS) feature comprising a pair of sidewalls spaced apart and each having a width X;
- and
- a plurality of pads each deposited with the width X on the ABS feature, wherein each pad comprises a hemispherical cross-section and has a circumferential diameter greater than width X, the plurality of pads capable of mitigating contact between one or more pads and a media surface with elastic deformation.
A data transducing assembly comprising:
- a slider presenting at least one transducer, wherein the slider has at least one air bearing surface (ABS) feature comprising a pair of substantially vertical sidewalls spaced apart and each having a continuous width X;
- and
- a pad deposited on a leading edge sidewall of the ABS feature, wherein the pad comprises a first and second substantially vertical pad sidewalls spaced the width X apart and a continuously curvilinear top surface configured with a circumferential diameter greater than width X to mitigate contact between the pad and a media surface with elastic deformation.
