ABSTRACT:
A system for storing data on a magnetic medium using spin polarized electron beams is provided. The system includes a source of spin polarized electrons and a storage medium disposed a selected distance from the source. The storage medium has a plurality of storage locations, each of which includes a layer of a first non-magnetic material, a layer of magnetic material deposited on the first non-magnetic material, and layer of a second non-magnetic material deposited on the magnetic material. The second material is included to scatter spin polarized electrons from the source into an interaction volume of the magnetic material. An electron optics system directs the source of spin polarized electrons to one of the plurality of storage locations.
