Abstract: A system includes a data storage medium comprising layers, an excitation circuit, and an emitter. Each layer comprises cells arranged in a horizontal plane. Cells in different layers are arranged in a vertical plane of the data storage medium. The excitation circuit excites a layer during excitation period. Exciting the layer changes an optical property of the layer during the excitation period. The emitter emits a first and a second beam onto a first and a second cell of the layer being excited during the excitation period to orient electrical charges within the first and the second cell to a first and second oriented values and their intensity to a first and second intensity values respectively. The first and second cells maintain the first and second oriented values and the first and second intensity values after the excitation period is over or in absence of the layer being excited.

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: Provided herein is an apparatus including a three dimensional crystalline structure including a number of storage locations. The storage locations are arranged in three dimensions within the crystalline structure. A light source is configured to focus a first light with a first energy on one of the storage locations in order to alter a characteristic of the storage location. The light source is further able to focus a second light with a second light energy on the storage location without altering the characteristic. A detector is provided to detect the second light energy.

Abstract: An apparatus includes a first storage cell with an electrical property. The first storage cell is configured to change the electrical property in response to a first light energy, and to maintain the change to the electrical property. The first storage cell is also configured to alter the change to the electrical property in response to a second light energy, and to maintain the alteration to the change to the electrical property. A second storage cell disposed over the first storage cell in a vertical plane of the first storage cell. A third storage cell disposed adjacent to the first storage cell in a horizontal plane of the first storage cell.
