HOLOGRAPHIC VERSATILE DISC
Need of Storage
‘Storage’ refers to computer components and recording media that retain digital data for some interval of time.
It provides the core function of modern computers- “information retention”.
The different types of storage are semiconductor, magnetic and optical storage.
Semiconductor memory uses semiconductor based integrated circuits to store information.
NEED OF STORAGE(cont.)
Magnetic storage uses different patterns of magnetization or a magnetically coated surface to store information.
Optical storage, the typical disc, stores information in deformities on the surface of the circular disc.
Eg.of optical storage are CD, CD-ROM, DVD, Blu-Ray Disc.
There have been some uncommon methoda also for storage purposes like:optical tape,molecular memory,holographic data storage.
WITH THE PROMISE OF TOMORROW’S OPERATING SYSTEMS INCORPORATING STUNNING GRAPHICAL INTERFACES THAT OFFER TRULY IMMERSIVE VIRTUAL REALITY AND NEXT GENERATION GAMES THAT WILL BLUR THE LINE BETWEEN FICTION AND REALITY,THE DEMANDS OF BEING ABLE TO QUICKLY STORE AND RETRIEVE ENORMOUS QUANTITY OF DATA IS EVER INCREASING.
HVD IS ANOTHER STEP TOWARDS A TRY TO MEET THESE DEMANDS.
INTRODUCTION
HOLOGRAPHIC VERSATILE DISC(HVD)--
was developed betwee april 2004 and mid-2008.
Has Media type:Ultra high-density optical disc.
Was Developed by HSD Forum.
Usage
ata Storage,
:High-definition video,
:Ultra High-definition video.
FEATURES
Data transfer rate is :1gbps
The technology permits over 10kilobits of data to be written and read in parallel in a single flash.
Most Optical Storage devices,such as a standard CD saves one bit per pulse.HVD’s manage to store 60,000 bits per pulse in the same place.
1 HVD=5800 CD’s=830 DVD’s=160 Blu-ray.
HOLOGRAPHY
Holography was invented by scientist Gabor,in 1947.
It is a technique that allows the light scatterred from an object to be recorded and reconstructed.
Holography can be use to store,retrieve and process information optically
Holography, at times is misconcepted as 3D-photogrophy,holography enables the scene to be viewed from different distances and at different orientation.
Contains information
about amplitude
and phase of
object
wave.
HOLOGRAPHIC MEMORY
Holographic Memory is a 3-dimensional data storage system that can store information at high density inside a crystal or photo polymer.
Holographic memory is a memory that can store information in the form of holographic image(hologram)
Unlike conventional memories,holographic memory use the volume to store the data.
HOLOGRAM
Hologram is a block or sheet of photosensitive material which records the diffraction of two light sources.
To create a hologram,laser light is used,that is splitted into a source beam and a refrence beam.
A Hologram preserves both the phase and amplitude of the object beam and reference beam.
COLLINEAR HOLOGRAPHY
HVD uses a technology called collinear holography
It uses two laser rays,one blue-green and one red.
These two beams are collimated into a single beam.
Blue-green laser reads the encoded data from the holographic laayer from the top.
Red laser serves the purpose of a refrence beam and also read the servo info.
