a disk-shaped optical data storage medium approximately 4-3/4 in. in diameter, which stores binary data as microscopic nonreflective holes or pits in an otherwise reflective surface, and is recorded and played back by rotation in an electronic device containing a laser. It is often referred to by its abbreviation CD. It is a type of optical data storage medium. Compact disks are used for recordings of music as well as of data for computer applications.
read only memory. A compact disk used for the permanent storage of text, graphic or sound information. Digital data is represented very compactly by tiny holes that can be read by lasers attached to high resolution sensors. Capable of storing up to 680 MB of data, equivalent to 250,000 pages of text, or 20,000 medium resolution images. This storage media is often used for archival purposes. Syn: optical disk, write-once read-many times disk.
A small optical disk on which text, data, sounds, visual images, and the like can be recorded digitally and then scanned, decoded, and transmitted by a laser beam to a computer monitor, television, or playback device.
A flat, circular plate on which read-only optical data is stored. A laser optical reader retrieves this information.
1. n. A disc, usually 4.75 inches in diameter, from which data is read optically by means of a laser. 2. n. A disc with information stored in the form of pits along a spiral track. The information is decoded by a compact-disc player and interpreted as digital audio data, which most computers can process.
Standard 12cm disc, which stores information digitally, read by laser optical system. Originally designed for music storage the CD is now used for many applications, some of which follow
a digitally encoded recording on an optical disk that is smaller than a phonograph record; played back by a laser
a digital peacock, exhibiting a rainbow of spokes under bright light
a molded plastic disc containing digital data
an optical disc used for storing digital data
a physical object as well as a musical record and it can express concepts or display values that aren't expressed by the music it contains
a single-sided storage medium
a small portable disc capable of storing relatively large amounts of data that can be read by a computer
Sound recording medium. In Reese Library, the compact disc collection is kept in the Audio Lab on the third floor. The Audio Lab is also equipped with listening equipment.
CD The Compact disc was introduced in the Early 1980s and has grown to become the single most widely used format. the music is stored digitally on a CD and as oppose to the analogue sound of vinyl records Company (sleeve) This is a sleeve which has the record copmanies design or logo on it. Typically the same sleeve was used for all releases on the label. Before the regular use of picture sleeves most 7" records were released in company sleeves. More recently they have made a comeback on promo releases. Some dealers refer to these as promo bags
Flat, round, portable, metal storage medium usually 4.75 inches in diameter and less than one-twentieth of an inch thick that store information using microscopic pits (indentations) and land (flat areas) that are in the middle layer of the disc. A high-powered laser light creates the pits and a lower-powered laser light reads items from the compact disc by reflecting light through the bottom of the disc. The reflected light is converted into a series of bits the computer can process. Compact discs are available as CD-ROM, CD-R, CD-RW, and DVD-ROM. A compact disc also is called an optical disc. 1.8, 7.4, 7.17- 25
A form of audio media storage where the sound is converted to a digital format and then stored in the form of microscopic â€œpitsâ€ representing the digital signal on metallic film encased in plastic. The pits are then read by a laser system as it scans the disc.
Compact format that resembles a small floppy disk, about 2.5 inches in diameter. Yet it has the capacity to hold about 74 minutes of music, comparable to a standard music CD.
An optical storage medium for digital data.
A high-density storage medium. A CD-ROM contains information to be read only. A CD-R can have new information "written" onto it.
A CD-ROM is a data version of a music CD capable of storing up to 700mb of data. Using a CD recorder it is possible to create new CD-ROMs. CD-ROMs cannot be changed after they have been written.
A plastic-coated, metalized disc that stores digitally encoded music for high-quality playback when read by a laser beam in a compact disc player.
The first commercially available digital audio playback format. Software is a 12cm diameter single sided silver disc containing digitally encoded signal to a 44.1kHz, 16-bit standard. Optical playback is by means of laser beam. Developed jointly by Philips and Sony CD has spawned a number of offshoot audio/video technologies such as CDi and CD-ROM.
A compact disc (CD) is a storage device, which is commonly used for permanently storing digital information on it.
Thin, round, reflective disc that stores digital data in the form of microscopic pits and lands and that can be read by a laser.
a family of standard flat, circular digital storage media formats that are written to and read by a laser, that are 120 mm (4.72 inches) in diameter, 1.2 mm (0.05 inches) thick, and made of clear polycarbonate plastic, and that store approximately 650 megabytes of data
High density storage media based on a 4.75" reflective optical disc. Can hold up to 650,000,000 bytes of data, that is equivalent to 12,000 images or 200,000 pages of text. CDs may all look the same, but there are numerous standards for different applications. The most common are defined below.
(CD) A small optical disk on which matter such as data or music is encoded. CD-ROMs (Read-Only Memory) are the kind used by computers and video game consoles in place of game cartridges or floppy discs. A CD-R (Compact Disc-Recordable) drive is a device which can not only read audio CDs and CD-ROMs, but also create ("burn", or "master") them.
A Compact disc is an optical medium used to store data or audio.
Optical digital disc storage that encompasses audio, video, and computer data. CD Digital Audio (CDDA): 44.1kHz audio, 80 minutes capacity. CD Recordable (CD-R): Write-once media, 700MB capacity, optimised for data use. CD ReWritable (CD-RW): Re-writable media, 700MB capacity, optimised for data use.

A Compact Disc or CD is an optical disc used to store digital data, originally developed for storing digital audio. The CD, available on the market in late 1982, remains the standard physical medium for commercial audio recordings as of 2007. An audio CD consists of one or more stereo tracks stored using 16-bit PCM coding at a sampling rate of 44.1 kHz.
