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. —Quarl ^(talk) 2006-01-15 12:29Z

I assume that is why the buffer underrun section is copied from another wikipedia article Stwalkerster 15:58, 4 September 2006 (UTC)

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)?—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)
