Talk:Optical disc recording technologies

New article
This is a new article to aggregate all the CD burning technology stubs (one of which got re-nominated for AFD the day it was kept). It's part of the new series on optical disc authoring. I have merged all the short articles here. &mdash;Quarl (talk) 2006-01-15 12:29Z

Once-Writeable
I must say I'm not famaliar with the new terms. It is the norm to refer to CDR as once-writeable instead of write once? CD Recordable drives were basically WORM drives. --NYC 18:18, 26 Dec 2006

Article Incomplete
This article is only about CD/DVD Recordables. It does not address the entire line of optical storage. Optical WORM (see also once-writable above) Write Once Read Many drives and media existed long before the CDs. MO Magneto-Optical drive which was rewritable also came before CDs althought MO only used optical info for track alignment, data were stored magnetically so technically not an optical disc. --NYC 18:18, 26 Dec 2006


 * MO is an optical disc. The reading of the data from the disc is done entirely optically.  It is the writing of the data that is done magnetically, but a laser is still required to heat the optical storage layer. 109.145.22.224 (talk) 12:55, 12 April 2012 (UTC)

Raw writing modes
Most "authoring" (I find the term misleading) software and "recent" (as in most ATAPI-compatible) drives allow the use of various "raw" writing modes (I've seen RAW16, RAW96P, and RAW96R). They seem to be distinct from DAO/SAO (between which most applications do not differentiate), but do in essence perform a whole-disc write. Are these methods wholly distinct from the existing ones? If so, how do they function (differently from TAO/DAO/SAO)?&mdash;Kbolino 21:21, 14 March 2007 (UTC)ť

DVD vs. CD
How is a CD disc physically different from a DVD disc? (Another way of asking why a CD can't be used with a DVD laser.) -- Beland (talk) 22:21, 27 July 2008 (UTC)


 * Actually, a CD can be used with a DVD laser. Most DVD video players will play audio CDs and they do it with the orange/red DVD laser.  Early DVD video players didn't even have a CD laser, even though they played CDs.  Only CD-R discs cannot be played with the DVD laser, and when attempting to play such a disc, the video player has to resort to its infra-red CD laser.  As to how the CD is different to the DVD?  It isn't.  It's just that the data tracks are much smaller in the latter.  Similarly, the CD-RW and DVD-RW are almost the same.  The CD-R and DVD-R use different dyes and reflective layer.


 * In theory, both CDs and DVDs can be read by the violet laser of a blu-ray player. In practice, blu-ray players use the orange/red DVD laser, because the violet laser has differing optical requirements and consequently has its own optical system. 109.145.22.224 (talk) 13:05, 12 April 2012 (UTC)

Longevity
The Longevity section is confusing. It compares "store-bought" media with "factory-manufactured" media. To me, these terms are not mutually exclusive. Wasn't the media I might buy in a store manufactured at a factory?? This section needs to be clarified or rewritten. I can't do it because I just completely don't get the point. —Preceding unsigned comment added by 98.221.120.172 (talk) 05:26, 15 February 2009 (UTC)
