The most common types are CD, DVD and Blu-ray. As removable media, optical discs superseded the earlier magnetic disk cartridges because they weigh less, have higher capacities and are not subject ...

Let's dive in. Disc rot is the chemical deterioration of optical discs, like as CDs, DVDs, and Blu-rays. Oxidation or chemical reactions cause the breakdown of the reflective layer of the disc.

As prices of writeable media and drives dropped, consumers rushed to duplicate games, create their own mix CDs, and backup their data on optical disc. It was a halcyon time. Fast forward to today ...

The data-transfer-rate of an optical disk is determined by the disk's rotational speed. Conventional CDs and DVDs, which use a 1.2-mm-thick polycarbonate substrate, could break from centrifugal ...

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).

Starting while at a Silicon Valley startup, Siros Technologies, we explored an alternative approach extnending current optical disk technologies. Here, a spinning disk is written and read by a focused ...

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 ...
