  • Data reader magnetic shield with CoFeNiB material
    Patent number: 9412401
    Abstract: A data storage device may be configured at least with a magnetic stack that contacts a magnetic shield. The magnetic stack can be disposed between first and second side shields and having at least one layer constructed of a CoFeNiB material. The magnetic shield may have a synthetic antiferromagnet with a non-magnetic layer disposed between first and second ferromagnetic layers.
    Type: Grant

  • Magnetic sensor shield pinned by a high-coercivity ferromagnet
    Patent number: 9251816
    Abstract: A magnetic sensor may generally be configured as a data reader capable of sensing data bits from an adjacent data storage medium. Various embodiments of a magnetic element may have at least a magnetic stack that contacts at least a first shield. The first shield can have at least one synthetic antiferromagnetic structure (SAFS) that is pinned by a high-coercivity ferromagnetic (HCFM) layer.
