Abstract
Official abstract text for this publication.
An apparatus disclosed herein includes a sensor with a free layer having cross-track easy axis anisotropy.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: a sensor stack of a read sensor including a free layer (FL) that has cross-track, uniaxial and bidirectional, easy axis anisotropy. 2. The apparatus of claim 1 wherein the cross-track anisotropy generates a cross-track anisotropy field that partially replaces magnetostatic bias of the FL from at least one of (1) permanent magnets (PMs) and (2) side shields. 3. The apparatus of claim 2 whe…
