Direct access storage format which is written and read by laser light
Any of the family of discs that relies on light[md]usually a laser beam[md]to read the data recorded on the disc.
a disk coated with plastic that can store digital data astiny pits etched in the surface; is read with a laser that scans the surface
a convenient storage media for many different purposes
a storage medium that can be written to and read using a low-powered laser beam
Medium that will accept and retain information in the form of marks or density modulation in a recording layer that can be read with an optical beam.
A type of storage medium read from and written to using a laser beam.
A recording medium for audio and/or video where a laser beam is used to record and play back digitally-coded information.
A device that allows the storage of either digital or analog signals on a disc.
A plastic disc that is "written" (encoded) and "read" using a laser optical device. The disc contains a highly reflective metal and uses bits to represent data by containing areas that reduce the effect of reflectance when illuminated with a narrow-beam source, such as a laser diode. The bits (data) are stored sequentially on a continuous spiral track starting from near the center of the disc and going to the outer edge.
The umbrella term for optical storage systems. A beam of light produced by a laser diode is used to retrieve the information from the discs. The discs are also, for the most part, non-erasable and sold with prerecorded digital information. The discs are very durable, flexible in terms of the types of information that can be accommodated, and can be accommodated, and can store an immense volume of information.
A disc that contains data readable by optical techniques. (T) (A) A disc with a plastic coating on which information, such as sound or visual images, is recorded digitally in the form of tiny pits and read using a laser.
a storage medium for electronic records that is written to and read by laser, such as CDs and DVDs
a storage device, usually called laser disks or compact disks (CDs); used to hold very large amounts of information permanently
A direct access storage device that is written and read by laser light. Certain optical discs are considered Write Once Read Many, or WORM, because data is permanently engraved in the disc's surface either by gouging pits (ablation); or by causing the non-image area to bubble, reflecting light away from the reading head. Erasable optical drives use technologies such as the magneto-optic technique, which electrically alters the bias of grains of material after they have been heated by a laser. Compact discs (CDs) and laser (or video) discs are optical discs. Their storage capacities are far greater than magnetic media, and are likely to replace magnetic hard disks and tape in the near future.
storage: A disc (not disk ... tsk) that is read and written to using light instead of magnetism. Their great advantage is that since the light beam is smaller than the magnetic flux path, they can hold much more data - as in a hundred times more! CD-ROMS are the most popular kind. Optical discs that behave just like floppies are not yet a reality, but two types come close: the WORM (write once, read many), used for archiving, and the magneto-optical disc, which is a combination of technologies as the name implies.

In computing, sound reproduction, and video, an optical disc is a flat, circular, usually polycarbonate disc whereon data is stored in the form of pits (or bumps) within a flat surface, usually along a single spiral groove that covers the entire recorded surface of the disc. This data is generally accessed when a special material on the disc (often aluminum) is illuminated with a laser diode. The pits distort the reflected laser light.
