In 2005, the patent for an Optical Storage Device in the form of a compact disc recorder was published by Peter J. Keller and Michael J. Updates? Despite its slowness, its superior capacity and recording characteristics make optical storage ideally suited to memory-intensive applications, especially those that incorporate still or animated graphics, sound, and large quantities of text. An older example, that does not require the use of computers, is microform. Early optical disks were not erasable—i.e., data encoded onto their surfaces could be read but not erased or rewritten. Blu-ray discs, which won the HDTV optical format war by defeating HD DVDs, can hold 25 GB for single-layer, 50 GB for dual-layer and up to 128 GB for quad-layer discs. A laser assembly reads the spinning disc, converting lands and pits into sequences of electric signals. optical data-storage.

Optical storage media includes CD-ROM, DVD-ROM, DVD-RAM, WORM cartridges, erasable optical cartridges and removable mass storage media, which includes flash drives and removable disk, or RDX. Optical disks can store much more data — up to 6 gigabytes (6 billion bytes) — than most portable magnetic media, such as floppies.There are three basic types of optical disks: CD-ROM:Like audio CDs, CD-ROMs come with data already encoded onto them.The data is permanent and can be read any number of … Optical storage is the storage of data on an optically readable medium. Besides higher capacity, optical-storage technology also delivers more authentic duplication of sounds and images. An older example of optical storage that does not require the use of computers, is microform. Example sentences with "optical data-storage", translation memory. 3D optical data storage is any form of optical data storage in which information can be recorded or read with three-dimensional resolution (as opposed to the two-dimensional resolution afforded, for example, by CD). A low-power laser scanner is used to “read” these pits, with variations in the intensity of reflected light from the pits being converted into electric signals.
