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.

Abstract: A read sensor and fabrication method thereof. The method includes forming a bottom stack that includes an antiferromagnetic (AFM) layer, a lower ferromagnetic stitch layer above the AFM layer and a sacrificial cap layer on the lower ferromagnetic stitch layer. The sacrificial cap layer is formed of a material that alloys magnetically with the lower ferromagnetic stitch layer. The method further includes substantially removing the sacrificial cap layer. After substantially removing the sacrificial layer, an upper ferromagnetic stitch layer is deposited on the lower ferromagnetic stitch layer of the bottom stack to form a stitch interface that provides relatively strong magnetic coupling between the lower ferromagnetic stitch layer of the bottom stack and the upper ferromagnetic stitch layer.

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.
