  • Patent number: 11631425
    Abstract: A magnetic recording head includes a write pole including an end proximal to a media-facing surface of the magnetic recording head, a return pole disposed a distance from the write pole in a down-track dimension of the magnetic recording head, and a writer coil configured to produce a magnetic flux in the write pole. The writer coil includes a first segment and a second segment. The first segment is disposed proximal to the end of the write pole and between the write pole and the return pole. The second segment is electrically coupled to the first segment. A thickness of the second segment in the down-track dimension is greater than a thickness of the first segment in the down-track dimension.

  • Patent number: 8659855
    Abstract: A magnetoresistive read sensor with improved sensitivity and stability is described. The sensor is a trilayer stack positioned between two electrodes. The trilayer stack has two free layers separated by a nonmagnetic layer and a biasing magnet positioned at the rear of the stack and separated from the air bearing surface. Current in the sensor is confined to regions close to the air bearing surface by an insulator layer to enhance reader sensitivity.

  • Patent number: 8649124
    Abstract: 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.

  • Publication number: 20080007570
    Abstract: Among other things, methods, systems and computer program products for enhancing a viewing experience of digital content includes displaying a predetermined sequence of multiple introductory digital content. The predetermined sequence minimizes a time delay before a main digital content is displayed. In addition, a graphical user interface can be loaded during a time of displaying a first introductory digital content from the predetermined sequence of multiple introductory digital content. User access of the loaded graphical user interface is enabled while the playing of the predetermined sequence of multiple introductory digital content is pending.

  • Publication number: 20070050402
    Abstract: A method and system for communicatively linking one or more items of digital content to a fixed media for presenting to a user. A graphical user interface capable of receiving data from a user is provided. The received data can be used to identify the one or more items of digital content to be linked to the fixed media. Based on the received data and a private seed value, a hash file is generated, the hash file includes a first hash code. An executable file is also generated. Also, an output file including the hash file and the executable file is generated. The generated output file is stored on a fixed media object.

  • Publication number: 20050162785
    Abstract: A transducing head includes a sensor element having a plurality of terminal pads and a shunt electrically connected with the sensor element in parallel for protecting the sensor element from electrical damage during fabrication of the transducing head. The shunt includes one or more fuses, where the shunt configured to be repeatedly tested around during fabrication to allow testing of the sensor element. The shunt is structured to be permanently electrically removable prior to operation of the transducing head by directing a shunt removal current through the shunt which effectively creates an open circuit in the shunt without causing a damaging current to flow in the sensor element. In another embodiment, the transducing head includes a shunt electrically connected with the sensor element in parallel.
