Abstract
The present disclosure includes methods of forming air bearing surfaces having multi-tier structures using nanoimprint technology and/or 3D printing technology. In some embodiments, a single stage of milling can be used to transfer a multi-tier photoresist pattern into a substrate (e.g., an AlTiC substrate).
Claims4
1-15 (canceled)
A slider body comprising:
- an air bearing face, wherein the air bearing face comprises a leading edge and a trailing edge;
- two side faces, wherein each side face is adjacent to the air bearing face;
- and
- a trailing edge face that is adjacent to the trailing edge of the air bearing face, wherein the air bearing face has a topography comprising at least a first face portion and a second face portion, wherein the first and second face portions are opposite a disc media surface when positioned in a hard disc drive, wherein the first face portion is separated by a distance from the second face portion, wherein the first face portion has an outer periphery and the second face portion has an inner periphery proximal to the outer periphery, wherein a sidewall extends between the outer periphery and the inner periphery, wherein the sidewall is linear or curvilinear, wherein a linear sidewall forms an angle with respect to the second face portion, wherein the angle is greater than 110 degrees or less than 80 degrees.
