New media allow DVD optical laser with 1 PetaByte storage capacity

New media allow DVD optical laser with 1 PetaByte storage capacity

disks gradually begin to “age” because of its relatively escaza for modern times compared to “spacious” Blu-ray discs, which thanks to its up to 4 layers can store up to 100GB.

A team of researchers from The Swinburne University’s Centre for Micro-Photonics have developed a technique that will significantly increase the of DVD media to the amazing 4.7GB of storage capacity (1 PetaByte).

To achieve this added around the standard 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 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.
