For techies: Laser discs store information in analog form, not digital form. There is no compression required, as the output of laser discs is analog video (NTSC), not digital data. You’ll also like: What is Optical Disc? What is CD-R (Compact Disc Recordable)? What is laser print...
A CD is a digital optical disc that was developed to store and play back audio recordings. It is a round, flat disc made of polycarbonate plastic, typically measuring 12 centimeters (4.7 inches) in diameter. CDs revolutionized the music industry by replacing analog formats such as vinyl records...
(0.047 in) thick. The underside of a CD consists of protective plastic over a reflective layer containing digital data,encodedas a series of pits and lands read by a laser as the disc spins in anoptical drive. A standard CD can store 700MBof data or up to 80 minutes of digital audio...
Expensive laser trimming in multibit Σ-Δ ADCs can be avoided by using techniques such as data scrambling to achieve the required linearity of the internal ADC and DAC.While integrating architectures (dual-slope, triple-slope, etc.) are still used in applications such as digital voltmeters, ...
From mono to stereo to surround sound, or from analog to digital to high-def, the beat goes on. Once upon a time, TVs and stereos were just heavy pieces of wooden furniture. They were self-contained, and their inputs or outputs were limited to antenna hookups and speaker jacks. Today,...
In a computerlike process, musical sounds are assigned binary digital codes of 0s and 1s that are etched on a 4.7-inch-diameter plastic-and-aluminum disc. When the disc is played, a laser beam picks up the coded "pits" of information, and the circuitry turns them back into analog ...
Digital optical: The old hat still fits Developed byToshiba in 1983, the digital optical cable was invented so consumers could transmit digital audio signals from CD and Laserdisc players to an AV receiver orstereo system. Thanks to the optical cable and its unique connector — known as a Tos...

about transposing electrical signals to light waves to deliver powerful, high-quality sound. It's simply another interval in the evolution of audio, as progressive as Thelonious Monk's compositions. From mono to stereo tosurround sound, or from analog to digital to high-def, the beat goes on...
A compact disc, also popularly known simply as a CD, is an optical storage medium with digital data recorded on its surface. A compact disc player is a device that reads the recorded data by means of an optical beam and accurately reproduces the original information (music, pictures, or ...
