ABSTRACT:
An optical storage system includes a frame (e.g., a rack-mount drawer), an environmental assembly (e.g., a power and cooling subsystem) supported by the frame, and a set of optical storage devices coupled to the environmental assembly. Each optical storage device has a base, a storage medium (e.g., a sphere-shaped holographic data storage structure) disposed on the base, and an optical assembly coupled to the base. The storage medium has a curved surface configured to store data in a digital manner thereon. The optical assembly is configured to optically write the data to and read the data from the curved surface of the storage medium.
