In one implementation, a read head for magnetic storage devices includes a lower shield, an upper shield, one or more lower leads, and a plurality of upper leads. The read head includes a plurality of read sensors, each read sensor of the plurality of read sensors including a first antiferromagnetic (AFM) layer. The read head includes a plurality of soft bias side shields disposed between and outwardly of the plurality of read sensors. The read head includes a plurality of second AFM layers disposed below the plurality of soft bias side shields along a downtrack direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Read head having one or more antiferromagnetic layers below soft bias side shields, and related methods","description":"The present disclosure relates to read head apparatus, and methods of forming read head apparatus, for magnetic storage devices, such as magnetic tape drives (e.g., tape drives).
