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.
