Removable disk media including holographic optical disk stacked in a tape cartridge shell

An automated data storage library, comprising:

• a media accessor including a cartridge shell gripper, and
• a removable disk media including:
• a tape cartridge shell having a structural configuration operable to be physically engaged by a cartridge shell gripper of a media accessor;
• and
• at least one optical disk of an octagonal holographic optical disk stack disposed within the tape cartridge shell, wherein a recording surface of each optical disk is at least partially extractable from the tape cartridge shell by an optical disk drive for at least one of writing data onto the optical disk and reading data from the optical disk, wherein:
• the octagonal holographic disk stack provides straight outside lines for being held inside the tape cartridge shell;
• the recording surface of the at least one optical disk of the octagonal holographic optical disk stack is octagonal shaped to facilitate a side-to-side movement of a beam generator and a beam detector relative to a fixed position of the at least one optical disk;
• and
• an optical extractor extracts the recording surface of the at least one optical disk at least to a point such that a radial line of the recording surface is accessible by the beam generator and the beam detector, wherein the octagonal shaped recording surface requires a lesser drive width in comparison to a corresponding square recording surface.
