Described are holographic storage mediums and method of making holographic storage mediums.

Holographic storage mediums, methods for producing the storage medium, methods for storing data in the holographic storage medium, and optical storage reading methods are described herein.

Only a person authenticated as a registered -in-advance person can take predetermined storage media out of the storage medium containing case.

The controller is connected to the storage mediums and is arranged to control IO access to the storage mediums.

The unit (7) can be moved over the storage racks (11-19) from a space (3-6) located between two storage racks to another space (3-6) located between two storage racks.

At least two of the storage media (1) have different storing capacities.

A media verification mechanism verifies the integrity and authenticity of storage media.

In one embodiment, the storage control of the computer storage system migrates the selected data from one of the at least one storage media to another of the at least one storage media according to the selected storage policy.

Also disclosed at the same time are two computer storage media.

Thus, the invention remarkably improves the hydrogen storage ability of hydrogen storage media.

The controller is connected to the storage mediums and is arranged to control IO access to the storage mediums.
