Abstract
Implementations described and claimed herein provide a synthetic antiferromagnetic (SAF) layer with canted pinning, wherein a down-track direction facing surface of the SAF layer has edges that are substantially parallel to pinning direction of the SAF layer.
Claims20
An apparatus comprising:
- a synthetic antiferromagnetic (SAF) layer with canted pinning, wherein a down-track direction facing surface of the SAF layer has edges that are substantially parallel to pinning direction of the SAF layer.
A sensor stack, comprising:
- a synthetic antiferromagnetic (SAF) layer, wherein a down-track direction facing surface of the SAF has a profile with at least one non-perpendicular angle.
A storage device comprising:
- a magnetic media;
- and
- a reader including a synthetic antiferromagnetic (SAF) layer, wherein direction of an edge of the SAF layer away from an air-bearing surface (ABS) of the reader is substantially parallel to a pinning direction of the SAF layer.
