Claims14
A hologram carrier, comprising:
- a hologram surface for storing hologram encoded information;
- a reference surface to facilitate acquisition of the hologram surface by a device, the reference surface comprising a plurality of steps arranged to interengage with a complementary formation on an access device so that the device becomes aligned to access at least some of the hologram surface;
- wherein said plurality of steps comprises different groups of steps, the groups of steps being oriented and formed such that a given specific access device, when the complementary formation thereof and a selected group of steps are interengaged, becomes aligned to access only specified parts of a hologram surface while access to other parts of the hologram surface with said specific device is prevented.
