  • Data reader with front shield coupling structure
    Patent number: 10186285
    Abstract: A data reader may consist of at least a magnetoresistive stack positioned on an air bearing surface. A portion of the magnetoresistive stack may be set to a first fixed magnetization by a pinning structure separated from the air bearing surface by a front shield that is set to a second fixed magnetization by a biasing structure. The front shield may be separated from the biasing structure by a coupling structure.
    Type: Grant
    Filed: April 20, 2017
    Date of Patent: January 22, 2019
    Assignee: Seagate Technology LLC

  • Method of manufacturing a recessed data reader pinning structure with vertical sidewall
    Patent number: 9922670
    Abstract: A data reader may have a magnetoresistive stack consisting of at least magnetically free and magnetically fixed structures with the magnetically fixed structure set to a first magnetization direction by a pinning structure separated from an air bearing surface by a front shield portion of a magnetic shield. The pinning structure can meet the front shield portion with a planar sidewall angled at 10° or less with respect to the ABS.
