摘要： Ferroelectric media includes a media surface that is scannable by a contact. The contact provides a read signal. A polarization pattern is written in first regions of the media surface. The polarization pattern represents position data. The first regions are selectively exposed to an energy source. The exposing provides an imprint to the polarization pattern that prevents subsequent erasure by the read signal.

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.
