    Abstract: A data reader may be configured at least with detector and injector stacks that each has a common spin accumulation layer. The detector stack may positioned on an air bearing surface (ABS) while the injector stack is positioned distal the ABS. The injector stack can have a diffusive layer with a larger spin diffusion length than mean free path.

    Abstract: A data reader may be configured at least with a magnetic stack positioned on an air bearing surface (ABS) and contacting a spin depolarizing layer that is a minority spin current carrier. The spin depolarizing layer can have a thickness and spin diffusion length corresponding to a net zero spin polarization at an interface of the magnetic stack and spin depolarizing layer.

    Abstract: A non-local spin valve (NLSV) sensor includes a bearing surface and a detector located proximate to the bearing surface. The NLSV sensor also includes a channel layer located behind the detector relative to the bearing surface, and in a substantially same plane as the detector. The channel layer has a front end that is proximate to the detector and a rear end that is distal to the detector. The NLSV sensor further includes first and second spin injectors, with the first spin injector located proximate to the rear end of the channel layer and positioned above the channel layer, and the second spin injector located proximate the rear end of the channel layer and positioned below the channel layer.

    Abstract: A read head includes a bottom shield and a bottom isolation layer that electrically isolates the bottom shield. The read head includes left and right reader stacks having respective bottom layers disposed on at least a portion of the bottom isolation layer. The left and right reader stacks are cross-track adjacent to one another. The read head also includes left and right bottom contacts electrically coupled to respective left and right bottom layers. A top shield is configured as a common top contact electrically coupled to respective top layers of the left and right reader stacks.
