then use Bragg selectivity to record subsequent images at the same location to achive storage densities as high as several Tbit/square inch. Starting while at a Silicon Valley startup, Siros ...

Using 3D storage techniques, scientists at the University of Shanghai for Science and Technology developed an optical disk capable of accommodating 1.6 petabits of data (that's 1.6 million gigabits).

Holographic disk drives have long promised to eclipse even the latest high-density optical storage media. Now finally, as Duncan Graham-Rowe reports, the promising three-dimensional approach to ...

Scientists have developed a new type of optical disc that can increase information storage capacity to the "petabit" level — 125 terabytes of data, or the combined storage capacity of about ...

A direct access storage device that is written and read by light. The most common types are CD, DVD and Blu-ray. As removable media, optical discs superseded the earlier magnetic disk cartridges ...

A storage system that contains multiple optical drives that read and write the media simultaneously. Libraries may hold one disc per drive or have storage for any number of discs or cartridges ...

In doing so, they reportedly devised a 3D nanoscale optical disk memory system capable of reaching petabit (Pb) capacity. To put this into perspective, the storage capacity of a DVD-sized disc ...

Magnetic storage makes use of a magnetisable coating ... Be more robust - a magnetic disk could be ruined by dropping it, because its moving parts may be damaged.

Sony has announced it will end Blu-ray Disc media production in February, marking the end of its nearly two-decade run.

However, reports in the Japanese media suggest the industrial giant will “gradually cease production of optical disc storage media,” including Blu-Ray products. Regardless, for now ...

Remember Blu-ray discs? The once-popular high-definition (HD) compact discs, designed to replace DVDs, are finally ending ...
