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.

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.

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.

Optical data storage media having high pressure-at-break strength

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.

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.

Embodiments are directed to recording digital data on an optically ablatable digital storage media. In one embodiment, a device configured to ablate portions of ablatable material on an optically ablatable digital storage media receives digital data that is to be recorded on a recording layer of an optically ablatable digital storage media. The recording layer is formed on a substrate with zero or more intervening layers between the recording layer and the substrate. The recording layer includes ablatable material capable of storing digital data. The device ablates the ablatable material in the recording layer according to a sequence defined by the received digital data such that the ablated portions correspond to data points of the received digital data.

A method for detecting extent of cross-linking of a high impedance polymer material during a pre-cure state, the method including: placing an insulated ground plane adjacent to the polymer material and substantially parallel to a sensor; applying a test signal through a sensor to the material and through a reference resistance; determining a voltage difference between the test signal applied to the material and the reference resistance as the reference voltage; and correlating the voltage difference as a relative indicator of the extent of cross-linking which has occurred within the polymer material. Also disclosed is a device for implementing the subject method.
