摘要: 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.

摘要: The presently disclosed technology teaches an improved voltage pattern for conductive tips utilized as moveable top electrodes for writing data bits into ferroelectric media. A conductive tip is dragged in contact or near contact with a ferroelectric surface forming a moveable top electrode on a ferroelectric media disk. A metallic film is deposited onto a bottom-side of the ferroelectric media forming a conductive bottom electrode. Applying electrical voltage pulses between the conductive tip and the bottom electrode induces polarization switching of the ferroelectric media under the head. The improved voltage pattern incorporates positive and negative overshoot voltages to induce a polarization switch in the ferroelectric media and positive and negative drag voltages to expand a polarized region on the ferroelectric media. Potential benefits of the improved voltage pattern include reduced cross-track blooming and reduced along-track blooming resulting in a more uniform track width and bit series length.
