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 As removable media, optical discs superseded the earlier magnetic disk cartridges because they weigh less, have higher capacities and are not subject ...

Scientists claim to have revealed a pathway to a new kind of 'efficient, ultra-high-density optical memory storage.' The ...

Writing data to the disc requires a green 515-nanometer laser as well as a red 639-nm laser. While traditional storage techniques use two dimensions, the new optical technology uses three and can ...

The optical discs segment is said to have recovered from last year´s sales plunge for “Discjet” machinery. The declining 2002 sales figures for audio CDs were offset by the growing DVD market. Trends ...

Two-photon technology, which relies on overlapping light beams, can be used for three-dimensional multilayer storage and promises capacities of up to 10 Tbyte on a DVD-size disk. Today's optical ...

Abstract: Numerical solutions of electromagnetic fields are presented for the scattering by pits and guide grooves on optical disks. The boundary element method can be applied to pit scattering of ...

An optical storage technology that uses multiple recording platters for higher capacity. Typically, DVDs and Blu-ray discs are available in two or more layers. In 1994, at its Almaden Research ...

In the simplest terms, an optical drive is the piece of hardware that lets a device read and interact with a disc. These discs can be CDs, DVDs, Blu-rays, game discs, and more. All optical drives ...
