A record and related method is provided for storing encoded information comprising a storage media, first marks on the storage media having a covert code characteristic, with the first marks conveying a covertly marked code and second marks preferably having an overt code characteristic which convey a second overtly marked code useful in decoding the covertly marked code. The system includes an acquisition subsystem utilizing a stationary radiation source and detector, a reconstruction subsystem, a computer-aided detection subsystem, and a 2D3D visualization subsystem. The low vacuum state provides an energy savings and reduced noise levels.
