摘要： A slider comprising a body having an air bearing surface (ABS), wherein the ABS extends between a leading edge and a trailing edge of the body. The slider comprises a transducer supported by the body and positioned near the trailing edge, wherein the transducer comprises a pole tip partially extending from the body. The slider comprises a surface defined in the body and forming the trailing edge, wherein the surface comprises a plurality of segments. A first segment of the plurality of segments extends from the ABS and is offset from a portion of the pole tip recessed within the body. The first segment is offset from the pole tip portion by a lesser extent than any other of the plurality of segments.

摘要： A slider scale package assembly in a head gimbal assembly (HGA) for electrically coupling a slider/magnetic recording (MR) head to a head interconnect circuit in a disc drive includes a flex circuit attached to the back of the slider/MR head which turns the slider/MR head into the slider scale package with at least one repositioned interconnect pad disposed at the back of the slider/MR head. The flex circuit further includes a conductive material, one end of which is electrically bonded to a bond pad of the slider/MR head, and the other end is electrically bonded to a conductive material of the head interconnect circuit via the interconnect pad. A plurality of flex circuits can be made in a sheet format and dividable into a plurality of individual flex circuits to be attached to a plurality of slider/MR heads. The bonding of the conductive material of the flex circuit to the slider/MR head and the bonding of the interconnect pad of the flex circuit to the conductive material of the head interconnect circuit can be done in a separate automated process.

摘要： A bond pad is elevated from a slider body by a conductive post. The bond pad is disposed atop the post, which typically possesses a cross-sectional area smaller than the surface are of the bond pad. Thus, rather than having the entire surface of the bond pad in contact with the slider body, only the cross-sectional area of the conductive post is in contact therewith. Alternatively, a bond pad may be split into two electrically coupled pads: one pad used for housing a permanent bond, and a second pad used for housing a temporary bond. The pad used to house the temporary wire bond may be disposed atop a sacrificial layer. After a lapping process, the sacrificial layer may be etched away, thereby permitting the temporary pad to be removed.

摘要： A clock head assembly intended for vertical engagement to a disc in a disc drive for purposes of providing an arrangement of precise timing marks on the disc for use by a servo-writer. The clock head assembly includes a slider of the 50% or 30% size and a spacer adhesively attached to the upper surface thereof. In order to minimize stresses induced in the slider by the adhesive bonding, and to ensure that the clock head is capable of correct flying performance relative to the disc, the present invention envisions that the spacer surface bonded to the slider, or slider bonding surface, has dimensions substantially half the size of the dimensions of the surface of the slider to which the spacer is bonded. In another aspect of the invention, the spacer is designed to be suitable for large batch production. In another aspect of the invention, the spacer includes, adjacent the surface opposite the slider bonding surface, an overhanging rim portion, which acts not only as a readily optimized surface for bonding the spacer/slider assembly to the head suspension of the clock head assembly, but also as a visual aid to correctly orient the spacer relative to the slider during bonding of the two together.
