Abstract: The system includes a data storage medium comprising cells, an excitation circuit, and an emitter. The cells arranged in a three dimensional space. The excitation circuit excites each cell independently. Exciting a cell changes an optical property of the cell. The emitter emits a first beam onto a first cell during a first excitation period to orient electrical charges within the first cell to a first oriented value and intensity of electric field to a first intensity value. The emitter emits a second beam onto a second cell during a second excitation period to orient electrical charges within the second cell to a second oriented value and intensity of electric field to a second intensity value. The first and second cells maintain the first and the second oriented values and the first and second intensity values after the first and second excitation periods are over, respectively.

Abstract: A system includes a data storage medium and a shockwave generator. The data storage medium includes cells and a plurality of layers. Each cell is configured to store information therein. At least two cells are arranged in a horizontal plane within a same layer of the plurality of layers of the data storage medium and at least two cells are arranged in a vertical plane in different layers of the plurality of layers of the data storage medium. The shockwave generator is configured to generate a shockwave signal that travels through a layer of the plurality of layers of the data storage medium. A target cell within the layer stores information responsive to a beam emitted from an emitter targeting the target cell as the shockwave signal is passing through the target cell. The target cell maintains the information after the shockwave signal exits through the target cell.

Abstract: Provided herein is an apparatus including a photon emitter array. The photon emitter array includes a number of photon emitters selectively oriented in a number of polarized orientations. The photon emitters are configured to controllably emit photons onto a surface of an article. The apparatus also includes a photon detector positioned to receive photons scattered from features on the surface of the article. The photon detector simultaneously receives photons oriented in the number of polarized orientations. In addition, the photon detector provides information for mapping the features on the surface of the article.

Abstract: A method includes projecting energy onto an annular edge of a glass substrate. The annular edge includes a first roughness. The first roughness is reduced to a second roughness with the energy. The energy reduces the first roughness without changing a roundness of the annular edge of the glass substrate.

Abstract: A method includes cutting an outer diameter into a glass substrate. An inner diameter within the outer diameter is also cut into the glass substrate. A first region inside the outer diameter and a second region inside the inner diameter are heated. The second region inside the inner diameter is cooled, wherein the cooling causes the second region to detach from the first region.
