Abstract: A data storage system comprises first and second storage layers, a reader and a writer. The first storage layer has a first coercive potential and a first polarization. The second storage layer has a second coercive potential that is less than the first coercive potential, and a second polarization that is coupled to the first polarization. The writer performs a write operation in which a write potential is imposed across the first and second storage layers, such that the first coercive potential is exceeded across the first storage layer and the second coercive potential is exceeded across the second storage layer. The reader performs a read operation in which a read potential is imposed across the first and second storage layers, such that the second coercive potential is exceeded across the second storage layer and the first coercive potential is not exceeded across the first storage layer.
