New media allow DVD optical laser with 1 PetaByte storage capacity
A team of researchers from The Swinburne University’s Centre for Micro-Photonics have developed a technique that will significantly increase the capacity of Standard DVD media to the amazing 4.7GB of storage capacity 1PB (1 PetaByte).
To achieve this added around the standard optical Laser lens (in charge of “burn” points “0″ and “1″ in the film data storage DVD), laser donut-shaped (or ring), which greatly reduces the original laser Beam diameter (a ten thousandth the thickness of a human hair), allowing this “burn” spots much smaller, significantly increasing the storage capacity of the medium.
Its developers claim that the technology is reliable, safe and economical to produce, employing standard optical and laser equipment.
This technology is expected to be implemented soon massively.
