Abstract: Embodiments of the present disclosure demonstrate a lapping carrier system for a bar to be lapped. The lapping carrier system may be configured with a single piece insert whose bridge is separated from a plurality of joints of the carrier insert by a varying distance. The varying distance can be greater at a medial portion of the bridge than at an end portion of the bridge to collectively form a parabolic shape. In some embodiments, a lapping insert can include a bridge with its length longer than the bar. In some embodiments in a lapping insert, the centerline between the end joint edge and the end finger edge extends beyond the edge of bar.

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).

Abstract: The present disclosure involves a row bar that includes a plurality of slider bodies to be lapped. At least one slider body includes at least a first row of a plurality of electrical contact pads; and a second row of a plurality of electrical contact pads. The first row of electrical contact pads extends along the cross-track direction at a first position in a lapping direction. The second row of electrical contact pads extends along the cross-track direction at a second position in the lapping direction. The second row of electrical contact pads are electrically isolated from ground. The present disclosure also involves related methods of locating electrical contact pads on a slider body.
