What is 
Holographic 
Storage?
• Holographic data storage is a high 
information storage volume 
technology that empowers 
information storage by making 
holographic pictures of every data 
instance on a bolstered medium.

Three-
Dimensional (3-
D) Storage
• It depends on the comparable idea 
of optical storage gadgets however 
it empowers the utilization of a 
single storage volume to store a lot 
of information. It is also known as 
Three-Dimensional (3-D) Storage.

Photorefracti
ve impact
• Holographic media is split into 
write-once (irreversible change), 
and rewritable media (change is 
reversible). 
• Rewritable holographic storage 
can be accomplished through the 
photorefractive impact in crystals.

Memory 
framework
• The memory framework comprises 
of the accompanying: a blue-green 
argon laser, beam splitters, 
reflectors, an LCD board, lenses, 
lithium-niobite crystal, and a 
charge-coupled device camera.

How would it 
work?
• The blue-green argon laser would 
be discharged, and with the 
assistance of the beam splitter, 
the laser shaft would be part into 
two beams known as the signal 
beam, which moves straight 
ahead, and the reference beam, 
which is coordinated through the 
side of the beam splitter.

APPLICATIONS OF 
HOLOGRAPHIC DATA 
STORAGE
Data Mining
• Data mining is the way toward 
finding patterns in a lot of 
information. 
• Data mining is utilized 
extraordinarily in enormous 
databases which hold potential 
patterns which can’t be recognized 
by human eyes because of the 
huge measure of information.

Petaflop 
Computing
• A Petaflop is a thousand trillion 
gliding operations per second. 
• The quick access in the 
exceptionally big amount of 
information given by holographic 
memory frameworks could be 
used in petaflop architecture.

Storage Volume
• Holographic memory can be utilized as 
expanded DRAM with 10ns access time, 
Hard disk drives, CD ROMs of huge storage 
volume and rock mounted of petabytes 
storage volume.

Advantages of 
Holographic 
Storage
• Holographic memory offers a storage 
volume of around 1 TB. 
• Speed of recovery of information in tens of 
microseconds contrasted with a data access 
time of practically 10ms offered by the 
quickest hard disk today.

Advantages of 
Holographic 
Storage Cont.
• Data pursuit is additionally quicker in 
holographic memory. In holographic 
capacity whole pages can be recovered 
where contents of at least two pages can be 
contrasted optically without having to 
recover the data contained in them. 
• If a few pieces of the medium are damaged, 
all data can still be acquired from other 
parts. All data can be recovered from any 
piece of the medium.
