WHAT IS IT………………….
Holographic data storage is a potential technology in the area of high-capacity data storage currently dominated by magnetic and predictable optical data storage. Magnetic and optical data storage devices rely on individual bits being stored as different magnetic or optical changes on the surface of the recording medium.

ADVANTAGES OF HOLOGRAPHIC DATA STORAGE:
• Long Durability – The Holographic data storage disk can last for at least 50 years.
• Extremely useful for medical archiving. (magnetic storage devices typically have storage life of 5 years).
