Abstract
A package for a holographic storage media disk (10) is provided that is comprised of a super structure (18) that is operable to hold the disk (10). The disk (10) is comprised of a photopolymer material that is formed in a disk-shaped member having a hub (14) disposed at the center thereof. The disk (10) is disposed in the structure (18) and then a cover (24) disposed thereover, the cover (24) being opaque. An access opening (28) is disposed within the cover (24) to allow access to the surface of the disk (10). A hub opening (26) is provided for allowing access to the hub (14). The hub (14) is disposed such that there is a light tight seal relative to the cover (24). A door (32) is provided for reciprocating over the opening (28) to light seal the package when data is not being recorded to the disk (10) or read therefrom. Additionally, layers of felt (161) and (163) are disposed on the interior surfaces of the cover to dampen any vibrations in the package, and a fiduciary marking opening (30) is provided for allowing access to fiduciary markings (164) disposed on the edge of the disk (10). The door (32) is operable to lock when in a portable mode and unlock when in an access mode.
