More Information
Summary:A data reader may be configured with at least a detector stack positioned on an air bearing surface and consisting of a spin accumulation channel continuously extending from the air bearing surface to an injector stack. The injector stack can have at least one cladding layer contacting the spin accumulation channel. The at least one cladding layer may have a length as measured perpendicular to the ABS that filters minority spins from the detector stack.
