Abstract
A system for three-dimensionally storing and encoding information in an optical storage medium. Information at a surface location is encoded according to the surface depth or width of the location. The information is then retrieved through the use of intensity measurements of light modulated by the depth or width of the storage location. The intensity of the light represents the data value stored at the location.
