Abstract
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.
Claims7
A method of shaping a trailing edge of a slider, the method comprising:
- encasing a transducer in alumina, the transducer on a wafer of ceramic material and including a pole tip;
- forming a trench above an end of the pole tip;
- and
- making a series of cuts into the alumina relative to a pole tip of the transducer to differentiate a slider head,
- wherein each cut of the series of cuts extends to one side of a respective pole tip, around the respective pole tip, and continues on another side of the respective pole tip.
