US 6,958,889 B2 · Slider with a compliant transducer interface

Abstract

A slider is used for supporting a transducing head proximate a rotating disc. The slider includes a primary air bearing having a disc opposing face bounded by a leading edge and a first trailing edge. An air bearing surface is defined on the disc opposing face. The slider further includes a secondary air bearing having a disc opposing face bounded by a front edge and a second trailing edge. The air bearing surface is defined on the disc opposing face. The air bearing surface has a pad proximate the second trailing edge wherein the transducing head is located on the pad. An interface connects the secondary air bearing to the primary air bearing and the interface displaces the transducing head vertically with respect to the primary air bearing to maintain head media spacing (HMS) between the transducing head and the disc substantially constant as the slider flies above the disc.

Dependent claims

A slider for supporting a transducing head proximate a rotating disc, the slider comprising:

a slider body having a disc opposing face bounded by a leading edge and a trailing edge, the slider body having a longitudinal axis;
an air bearing surface defined on the disc opposing face, the air bearing surface having a pad proximate the trailing edge wherein the transducing head is located on the pad;
and
an interface defined on the disc opposing face of the slider body and substantially surrounding the transducing head wherein the interface displaces the transducing head vertically with respect to the slider body in response to surface topography of the disc to maintain head media spacing (HMS) between the transducing head and the disc at a substantially constant separation distance as the slider flies above the disc.
