Talk:Double-density compact disc

Variations of DD Compact Disc
I got two questions: Does this format use regular recordable CDs? Is this format in any related to the Sega Dreamcast GD-ROM?--Kevin586 19:49, August 22, 2005 (UTC)
 * No. Double Density needs DD-CD-discs. No. GD-ROM is different from DD-CD. See . Henri Tapani Heinonen 16:38, 25 August 2005 (UTC)

Lack of source claim
I don't understand the claim that this article lacks source. As per the article, the technology is present in two different engineering standard specifications. The claims can be verified by reading the said specifications. — Preceding unsigned comment added by Daviburg (talk • contribs) 19:08, 19 March 2012 (UTC)
