20120268843 | Shaped Magnetic Write Pole - 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. | 10-25-2012 |
20120327535 | Chamfered Magnetic Write Pole - 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. | 12-27-2012 |
20130010386 | Magnetically Biased Write Pole - An apparatus and associated method provides 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. | 01-10-2013 |
20130242432 | RECORDING HEAD COIL STRUCTURE - A recording head comprising a write pole and a coil structure asymmetric with respect to the write pole and configured to generate more magnetic flux on a trailing side of the main pole than the magnetic flux on a front side of the main pole. | 09-19-2013 |
20130258525 | Write Yoke with Stabilizing Layer - An apparatus is provided that generally relates to a data writer that may be constructed with a write pole coupled to a yoke. The yoke may be configured with a stabilizing layer that stabilizes magnetic domains present in the yoke. In some embodiments, the yoke has first and second sub-yokes. | 10-03-2013 |
20140146417 | Data Writer with Tapered Side Shield Sidewalls - 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. | 05-29-2014 |
20140268416 | RECORDING HEAD COIL STRUCTURE - A recording head comprising a write pole and a coil structure asymmetric with respect to the write pole and configured to generate more magnetic flux on a trailing side of the main pole than the magnetic flux on a front side of the main pole. | 09-18-2014 |
20140376131 | Data Writer with Tapered Side Shield Sidewalls - 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. | 12-25-2014 |
