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.

Data reader magnetic shield with CoFeNiB material

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.

A data storage system may be configured at least with a seed lamination that is disposed between a magnetic stack and a magnetic shield. The seed lamination may be constructed and operated with a coupling buffer layer and a seed layer with the coupling buffer layer fabricated of an alloy of cobalt and a transition metal.

Magnetic stack coupling buffer layer

A magnetic element may generally be configured at least with a magnetic stack contacting a leading shield with a seed trilayer. The seed trilayer may have a magnetic layer formed of a metal material and disposed between first and second non-magnetic layers while at least one of the non-magnetic layers constructed of the metal material.
