15. HOLOGRAPHIC
Data Storage
By Black Mambas

16. 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.

17. 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).
