Abstract

A magnetic storage includes a non-magnetic substrate. A plurality of discrete single magnetic domain elements formed of a magnetic material separated by nonmagnetic materials are carried on the non-magnetic substrate. Each single magnetic domain element has the same size, shape and has, without an external magnetic field, two quantized magnetization values. The two magnetization values are of substantially equal magnitude but of differing vector directions. The plurality of single domain elements are adapted for magnetic storage of information based upon direction of the magnetization vector. Each single magnetic domain element is used to store a bit of binary information. Writing each bit becomes to flip the quantified magnetic moment directions. Each bit can be tracked individually. The switching field of each bit can be controlled by controlling the size and shape anisotropy of each bit. Methods of fabricating the magnetic storage medium include obtaining the non-magnetic substrate and forming the plurality of single magnetic domain elements on the substrate.
