ABSTRACT:
A storage device has a stator layer, an emitter layer, and a rotor layer. The rotor layer has a plurality of data clusters, each having a substrate which is electrically isolated from the other data clusters by a dielectric material. Another storage device has a means for electrically isolating a plurality of data clusters, each having phase change media coupled to a conductive substrate, from each other. The storage device also has a means for reading a differential signal from each of the data clusters based on currents which flow from the phase change media to the conductive substrate in each data cluster. A method of electrically isolating conductive regions on a micromover device is also provided.
