	Compact Disc - Wikipedia, the free encyclopedia
		The Compact Disc logo was inspired by that of the previous Compact Cassette.
		Compact disc technology was later adapted for use as a data storage device, known as a CD-ROM, and to include record once and re-writable media (CD-R and CD-RW).
		Compact discs are made from a 1.2 mm thick disc of very pure polycarbonate plastic.

	Compact disc - Encyclopedia, History, Geography and Biography (Site not responding. Last check: 2007-10-12)
		Mini-CD Compact discs are made from a 1.2 mm thick disc of polycarbonate plastic coated with a much thinner layer of Super Purity Aluminium (or rarely, gold, used for its data longevity, such as in some limited-edition audiophile CDs) layer which is protected by a film of lacquer.
		Discs are consequently much easier to ruin by scratching the label side, whereas clear-side scratches can be repaired by refilling them with plastic of similar index of refraction.
		By the time the compact disc was introduced worldwide digital recording and mixing was becoming commonplace among recording artists and producers known for their interest in fidelity.

	Red Book (audio CD standard) - Wikipedia, the free encyclopedia
		The first edition of the Red Book was released in June 1980 by Philips and Sony; it was adopted by the Digital Audio Disc Committee and ratified as IEC 908.
		It also specifies the form of digital audio encoding (2-channel 16-bit PCM clocked at 44100 Hz).
		On the disc, the data is stored in sectors of 2352 bytes each, read at 75 sectors/s.

	Digital Audio Technology on CD
		Compact Discs were designed for high quality noise-free music using a consumer friendly physical format.
		The Compact Disc Digital Audio (CD-DA) standard was developed by Philips and Sony and introduced into the market in Japan in October 1982 and in USA and Europe in early 1983.
		CD digital audio should provide the quality needed for all audio applications, but for the purist this is not always enough.

		It is the original and oldest Compact Disc standard and the foundation for all the other standards developed later.
		The introduction of this architecture allowed compact discs to be used as an archival medium for computer data.
		Discs following this standard can be played in a consumer CD player as standard audio discs and in a computer CD-ROM player as multimedia discs.

	Understanding CD-R & CD-RW - Audio Recording
		Digital material such as existing MP3 files or CDs are conveniently read directly from the hard drive, recorder or from a separate CD or DVD-ROM drive.
		When producing a compressed digital audio CD these files are written to disc just as they come and, depending upon the recording software used, may be accompanied by MultiAudio or other navigational information.
		Written discs can then be played back in MultiAudio compliant devices and even in compressed digital audio units not supporting the specification, albeit in a more limited fashion.

	CD Audio Facts
		On vinyl and audio cassettes, the audio waveform is recorded as an analogue signal.
		Digital coding allows the use of error correction codes, which are necessary to correct errors resulting from the manufacturing process and minor damage or marks which may occur from handling and use.
		Digital encoding can produce virtually noise-free results but an error correction scheme is needed to protect against minor damage to the CD which can produce incorrect data.

	Digital Audio in Worship
		There are a few basic properties of digital audio data that should be understood.
		The same basic situation exists with digital audio compression - several lossy methods are available which, depending on the compression ratio, begin to sound worse than the original, but which can result in astoundingly small file sizes.
		Aside from the compact disc digital audio standard, which is specific to CDs, several common formats of digital audio data files exist, that are relevant to this discussion.

	CDRoller- Reading audio CD : digital audio extraction engine
		Because audio discs are manufactured per the Red Book Standard, all audio compact discs will play in any audio compact disc player.
		For the insiders, using your sound card, the digital data from the disc are converted to an analog signal, which is then digitized again by the sound card.
		The second problem is that an audio sector as "raw" sector has no auxiliary field for layered error correction (L-EC) therefore reading block of damaged sectors can result in invalid data recorded to the output file.

	The Euphoria Tech Help Page (Site not responding. Last check: 2007-10-12)
		There's one hitch: High-quality audio is a real pig when it comes to file sizes and network bandwidth required for transmission.
		Digital audio for CDs is obtained by using 16-bit (two-byte) numbers to represent samples of the analog signal.
		In order to trim the file sizes, we have to accept audio quality that is quite a bit lower than compact disc.

	CD-DA
		The audio stream uses Pulse Code Modulation (PCM) which is equivalent to a reordering of a WAV or AIFF file minus any header or footer.
		It is worth noting that the largest 'length' number which can be written to the disc is 79:59:74; longer discs cannot tell the truth about their length and later track starts are not specifiable in the TOC.
		A data disc has an extra layer of error correcting code (ECC) which uses about 13% of the space; that is not used for audio so the player provides error concealment to reduce the effect of misreading.

	Audio Compact Disc Player
		Analog sound data is digitized by sampling at 44.1 kHz and coding as binary numbers in the pits on the compact disc.
		The tracks on a compact disc are nominally spaced by 1.6 micrometers, close enough that they are able to separate reflected light into it's component colors like a diffraction grating.
		The detection of the binary data stored in the form of pits on the compact disc is done with the use of a semiconductor laser.

	Ogg Frog: Why Can't I Play the CDs That I Burn?
		CD-R discs are said to be "burned" because heat from a focussed laser beam darkens a chemical dye that forms one layer of the disc.
		Audio and data CDs are encoded with extra error correction data in each disc sector, to recover from data loss caused by scratches or dust on the surface of the disc.
		Rippers that use CDDA Paranoia as their low-level ripping engine are likely to work best, as it has particularly robust error correction built-in.

		One needs two pieces of software to convert the compact disc digital audio (cdda) data encoded within the thin layers of your favorite CD to an MP3 (or other compressed autio) file.
		The ripper's job is to take digitally stored information on the compact disc, and transfer it to your computer's hardrive in a format the computer can recognize.
		Its job is to perform compression routines, and mathematically filter the audio data your ripper extracted from the CD.

	Service and Support - Important Notice About "DualDisc" To Prevent Product Damage (Site not responding. Last check: 2007-10-12)
		A DualDisc typically contains DVD content on one side of the disc, such as music video clips and multi-channel audio sound material in DVD Video/Audio format, and non-DVD content (which may incorrectly be referred to as a CD side) on the other side, such as digital audio material.
		Pioneer understands that, although a DualDisc may refer to a CD side, the "non-DVD" side is not compliant with the Compact Disc Digital Audio specification and does not bear the CD logo.
		Inappropriate disc setting in Pioneer's portable DVD players and portable/slim type computer drives may cause scratches on the disc and/or irregular playback.
