Abstract:
A storage device comprising:a field emitter generating an electron beam current; a storage medium in close proximity to the field emitter, the storage medium having a plurality of storage areas for storage of information, each of the plurality of storage areas being in one of a plurality of states to represent the information stored in that storage area; such that: an effect is generated when the electron beam current bombards one of the storage areas; the magnitude of the effect depends on the state of the bombarded storage area; the information stored in the bombarded storage area is read by measuring the magnitude of the effect; a micromover for causing a periodic change in the relative positions between the field emitter and the storage medium, thereby generating a periodic field emitter trajectory; and wherein the shape of the periodic field emitter trajectory is one of a triangle wave shape, a sawtooth wave shape, a Lissajous wave shape, a rectangle wave shape, and a sinusoidal wave shape.
