摘要： A method for producing magneto resistive heads includes the steps of positioning at least two magneto resistive elements in spaced relation to one another and placing the at least two magneto resistive elements in an ion milling environment where material is removed nonselectively from items in the environment. A property of at least two of the plurality of magneto resistive elements is monitored. In response to monitoring, one of the at least two magneto resistive elements is dynamically covered to prevent additional removal of material from the covered magneto resistive element.

摘要： Recording heads for data storage systems are provided. Recording heads illustratively include a write pole, a bumper, a dielectric layer, and a surface. In some embodiments, a portion of the surface includes portions of the write pole, bumper, and dielectric layer. The write pole, bumper, and dielectric layer are illustratively made from materials that have polishing rates. In some embodiments, the polishing rate for the write pole material is more similar to the polishing rate for the bumper material than it is to the polishing rate for the dielectric layer material.

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.
