Abstract: An optical tape data storage is disclosed. An optical tape includes a substrate in a linear thin film shape and a recording layer deposited on the substrate. An irreversible optically detectable change is formed in the recording layer upon application of energy to the recording layer such that data is recorded on the recording layer by forming optically detectable changes. The recording layer may comprise a metal, a metal alloy, a metal oxide, a metalloid, or any combination thereof. The optical tape may further include an adhesion promotion layer for improving adhesion of the recording layer and the substrate, a reflective layer for providing optical contrast to an adjacent layer, and/or an absorptive layer positioned adjacent to the recording layer to absorb ablatable material not entirely ablated during ablation.

Abstract: Recording data in a permanent solid state memory device forms voids in a patterned data layer between a first wire array and a second wire array. Wires of the first wire array extend transversely to wires in the second wire array thus creating a crossbar array. The conductive material in the data layer is made of a carbon allotrope such that when current is passed through the carbon allotrope, the carbon is quickly oxidized (burned) leaving a complete gap (void) where the conductive material (i.e., fuse) once was. One of the advantages of this method is that the fuse material is fully oxidized, such that there is no material left over from which dendrites can grow. A horizontal configuration in which the data layer is a bowtie structure is also disclosed.

Abstract: A permanent solid state memory device is disclosed. Recording data in the permanent solid state memory device forms voids in a data layer between a first wire array and a second wire array. Wires of the first wire array extend transversely to wires in the second wire array. The data layer is at least partially conductive such that a voltage applied between a selected first wire in the first wire array and a selected second wire in the second wire array creates a heating current through the data layer at a data point between the first wire and the second wire. The heating current causes a data layer material to melt and recede to form a permanent void. Control elements are operably connected to apply voltages to predetermined combinations of wires to form permanent voids at data points throughout the solid state memory device.

Abstract: Optical information media that contain a data layer material that is substantially inert to oxidation and has a defined melting point range are disclosed. The inertness to oxidation and melting point range make the media particularly attractive for long-term information storage.

Abstract: Optical information media having high pressure-at-break values, and methods for determining pressure-at-break values are disclosed. The media have high structural integrities, and are designed to confer greater resistance to delamination forces as compared to conventional optical information media.

Abstract: Optical information media containing encapsulated data layers are disclosed. Selective layering of materials in inner radial, middle radial, and outer radial zones allows for the faces and edges of at least the data layers to be encapsulated by other materials, resulting in increased resistance to harmful environmental agents such as oxygen and moisture.

Abstract: Optical information media containing a metal material layer and a carbon material layer are disclosed. The layering of the metal material layer and the carbon material layer are designed to reduce or eliminate problems associated with oxidation and berm formation during writing of data to the media.
