  • T-shaped write pole
    Patent number: 9218825
    Abstract: A magnetic element may be generally configured with at least a write pole that has leading and trailing regions on an air bearing surface. The leading region may have a trailing width connected to a leading width of the trailing region via a transition feature to form a substantially T-shaped cross-section on the air bearing surface.

  • Data writer with tapered side shield sidewalls
    Patent number: 9218824
    Abstract: A data writer may be generally configured at least with a write pole that has a pole sidewall and a continuous first taper angle connecting leading and trailing edges. The write pole can be positioned adjacent to a side shield that is configured with first and second shield sidewalls tapered to a shield tip that is the closest point between the write pole and side shield.

  • Magnetically biased write pole
    Patent number: 9099108
    Abstract: An apparatus may be constructed with a magnetic element, such as a data transducing head. A first permanent magnet may be configured to bias the write pole to decrease remnant magnetization and erasure after write (EAW). The first permanent magnet can be separated from the write pole be a predetermined distance.

  • Chamfered magnetic write pole
    Patent number: 8804283
    Abstract: A write pole can have a magnetically conductive pole tip has at least one corner. The at least one corner may be chamfered to limit magnetic saturation of the conductive pole tip. The conductive pole tip can have one or more beveled surface that has a chamfered corner which extends a predetermined distance along an edge of the write pole.

  • Shaped magnetic write pole
    Patent number: 8582234
    Abstract: A magnetic shield is adjacent a write pole. The write pole has a body portion with a body thickness and an extension portion with parallel first and second sides that each tilt towards the magnetic shield at a predetermined angle proximal to an air bearing surface (ABS). The extension portion may be capable of enhancing a write field gradient of the magnetic shield by reducing magnetic saturation.
