  • Patent number: 9165573
    Abstract: A method of a parting a slider from a slider bar is disclosed. The method includes receiving a slider bar comprising a plurality of sliders and having an air bearing surface (ABS) side and a back side opposite to the ABS side and parting at least one slider from the slider bar with a cutter, wherein the cutter enters the slider bar at least in part on the backside and exits the slider bar at least in part on the ABS side and the ABS side is facing away from the cutting direction by a predetermined acute angle.

  • Patent number: 8418353
    Abstract: A method for providing energy assisted magnetic recording (EAMR) heads using a substrate are described. The substrate has front and back sides and apertures therein. The apertures are through-holes between the front and back sides of the substrate. The method includes providing a transmission medium in the apertures and fabricating EAMR transducers on the front side of the substrate. The EAMR transducers correspond to the apertures and the EAMR heads. The method also includes electrically insulating the back side of the substrate. The back side of the substrate is also prepared for mounting of the lasers. The lasers then are coupled the back side of the substrate. The lasers correspond to the EAMR heads and are configured to provide light through the apertures to the EAMR transducers. The method also includes separating the substrate into the EAMR heads.

  • Patent number: 8024748
    Abstract: A method and system for providing an energy assisted magnetic recording (EAMR) disk drive are described. The EAMR disk drive includes a slider, at least one EAMR transducer on the slider, and at least one laser coupled with the slider. The slider has a slider back side, a trailing face, and an intersection. The trailing face and the slider back side meet at the intersection. The trailing face makes an angle different from ninety degrees with the slider back side at the intersection. The laser(s) have an optical axis and are optically coupled with the trailing face of the slider. The optical axis is substantially perpendicular to the intersection and parallel to the slider back side.
