20080253021 | Non-magnetic contact enhancement feature - A transducer having an external contact surface includes a writer and a contact member. The writer has a portion extendable beyond the external contact surface. The contact member surrounds at least a portion of the extendable writer portion. | 10-16-2008 |
20110310511 | APPARATUS INCLUDING MODIFIED WRITE POLE TIP - An apparatus that includes a write element including a write element tip having a leading edge, a trailing edge, and first and second side edges connecting the leading edge to the trailing edge, wherein the trailing edge is non-planar; a trailing shield proximate the trailing edge of the write element; a first side shield proximate the first side edge; and a second edge proximate the second side edge. | 12-22-2011 |
20130000107 | Contact feature for use with transducing devices - A transducer having an external contact surface includes a writer and a contact member. The writer has a portion extendable relative to an adjacent portion of the external contact surface. The contact member surrounds at least a portion of the extendable writer portion and is spaced from the extendable writer portion. The coefficient of thermal expansion of the contact member is approximately equal to the coefficient of thermal expansion of the extendable writer portion. | 01-03-2013 |

20110179634 | METHOD OF MAKING A TRANSDUCER WITH A CONDUCTIVE MAGNETIC LAYER - A transducer includes a first layer that is selectively deposited in a contact region to form a core, and selectively deposited in a transducer region to form a first element of the transducer. The transducer includes an electrically conductive magnetic deposit. The electrically conductive magnetic deposit forms a sidewall on the core. The electrically conductive magnetic deposit forms a second element of the transducer in the transducer region. The second element of the transducer has a planarized surface that is coplanar with a planarized surface of the sidewall. | 07-28-2011 |
20110281023 | SELF-ALIGNED BEVELS FOR WRITE POLES - A method of depositing material onto a base portion of a wafer is disclosed. The method includes forming a bevel into a portion of a surface of the base portion of the wafer and depositing a first layer of conductive material onto the beveled portion of the base portion so that part of the first layer includes a wedge shape above the surface of the base portion. A second layer of conductive material is deposited onto the base portion including the portion of the base portion onto which the first layer of material is deposited. | 11-17-2011 |

20120147503 | DOUBLE SHELL WRITERS - An apparatus illustratively includes a return pole (RP) and a shield. The RP has a first RP magnetic layer, a second RP magnetic layer, and a RP non-magnetic layer. The RP non-magnetic layer separates and magnetically decouples the RP first and second magnetic layers. The shield has a first shield magnetic layer, a second shield magnetic layer, and a shield non-magnetic layer. The shield non-magnetic layer separates and magnetically decouples the shield first and second magnetic layers. A method illustratively includes generating magnetic flux and collecting the magnetic flux through an inner magnetic shell. | 06-14-2012 |
