However, the new work multiplies the bit storage density of optical media by wavelength multiplexing and quantum spin state transitions. You might already have a good idea about how the ...

“The electronics and entertainment conglomerate will also gradually cease production of optical disc storage media products, ...

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 ...

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 As removable media, optical discs superseded the earlier magnetic disk cartridges ...

However, scientists think they may have found a way to bring optical disc storage roaring back – with a massive upgrade that massively increases data density. Researchers at the University of ...

Scientists have proposed a new type of data storage device that harnesses the powerful properties of quantum mechanics. The ultra-high-density optical memory device would consist of numerous ...

The traditional way to cram more data onto optical disks, such as DVDs, is to create smaller features on their surfaces using lasers with shorter wavelengths. The latest storage media, such as Blu ...

Researchers in China have unveiled a new optical storage technology that promises to redefine data storage capabilities. Using 3D storage techniques, scientists at the University of Shanghai for ...

Holographic data storage is poised to change the way we write and retrieve data forever. After many years of developing appropriate recording media and optical read–write architectures ...

Secondary storage is needed to keep programs and data ... There are different types of optical media: ROM media have data pre-written on them. The data cannot be overwritten.

Magnetic storage makes use of a magnetisable coating. Magnetised dots are made on the surface of the material. These dots are created, read and erased by very small electromagnets. Examples ...
