Introduction
Topic : Disk storage & relevant technologies
Title : Protein based optical data storage
Why new technology
Protein feasibility
Types of protein
bR
Why new technology?
Design and construction of smaller is becoming difficult
Magnetic & semiconductor based storage are nearing up their limits
The cost of producing smaller chips is skyrocketing
Need for speed
But Demand for higher capacity is increasing
More Problems
Semiconductors rely on electrons
Electrons although fast have mass and are limited in velocity
Photolithography is used in manufacturing semiconductor based devices
light source must be at least as small as the features we're trying to fashion
the wavelengths of the spectrum are fixed and will not change
Optical computing(using Protein) will over come these
Optical computing relies on photons
Photons based on light waves have no mass & travel at the speed of light
Protein based storage
bR protein is used as storage
20 times more storage than Blue-ray disc
Stores 50 TB of data
New protein coated DVDs –medical,entertainment,defence
Molecular switches-reduction in hardware size(1/20th) of present size
More reliable
More efficient
Unaffected by electromagnetic interference
Faster
Incorporation of much thinner materials
No high temperature manufacturing
Applications
Storage of digitized hospital x-rays that will allow a physician to instantly obtain high-resolution images of a patient’s records stored hundreds of miles away.
Cable television stations and potentially individuals, will be able to store countless hours of movies on a single cube
