Researchers at the University of Shanghai for Science and Technology have come up with an optical storage device that has the same shape and size as a DVD or Blu-Ray disc — but can hold a ...

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 As removable media, optical discs superseded the earlier magnetic disk cartridges ...

To put this into perspective, the storage capacity of a DVD ... only store data on the surface layer of the disc, which is why this optical memory device can hold gargantuan amounts of data.

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 ...

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).

But fear not, data hoarders. Two companies have stepped up to reassure the Japanese market that they'll keep producing high-quality optical media: Verbatim and I-O Data.

The traditional approach to this problem was to spatially modulate a laser beam with an image of ~one million bits, record a hologram of this image, then use Bragg selectivity to record subsequent ...

Data is stored in binary form on secondary storage devices ... erase the data the device holds. Optical devices use a laser to scan the surface of a spinning disc made from metal and plastic.

such as USB memory sticks optical storage devices, such as CD, DVD and Blu-ray discs magnetic storage devices, such as hard disk drives Solid state storage is a special type of storage made from ...

A storage system that contains multiple optical drives that read ... Also called an "optical jukebox," such devices are made for CDs, DVDs, magneto-optic discs and WORM discs.
