Portable data storage assembly having a holographic data storage layer and an optical tracking layer

A data storage and retrieval system, comprising:

• a plurality of storage slots;
• a plurality of portable data storage assemblies removeably disposed in said plurality of storage slots, wherein each of said portable data storage assemblies comprises a center point, a periphery, a holographic data storage layer, an optical tracking layer, wherein said holographic data storage layer comprises a first storage band comprising a first plurality of encoded holograms and a second storage band comprising a second plurality of encoded holograms, wherein said second plurality of encoded holograms is greater than said first plurality of encoded holograms;
• a data drive comprising a beam splitter, a first lasing device, a second lasing device, a first optical sensor comprising a reflective spatial light modulator, a second optical sensor, a drive controller, and a drive motor, wherein each of said plurality of portable data storage assemblies can be removeably disposed in said data drive;
• an accessor moveably disposed therein and comprising a vertical pillar, a lifting servo section moveable disposed on said vertical pillar, and a gripper disposed on said lifting servo section, wherein said accessor can retrieve a designated one of said plurality of portable data storage assemblies, transport that designated portable data storage assembly to said data drive, and disposed said portable data storage assembly into said data drive.
