Talk:DualDisc

message: How do they do it? The data layer on a CD is beneath its printing area. The DVD's data layer is sandwiched in the middle of two polycarbonate layers of half the thickness. How do they combine the two physically incompatible formats?
 Side A surface
---------------- CD data layer
                   0.6 mm
---------------- DVD data layer
                   0.6 mm
----------------
 Side B surface
Possibly you can build a CD/DVD hybrid disc that is readable only from Side B:
* CD: laser -> side B -> DVD (semi-transparent) -> CD data
* DVD: laser -> side B -> DVD data
How do you build a disc "with one format on one side of the disc and the other on the opposite"? Using two semi-transparent layers?
* CD: laser -> side B -> DVD (semi-transparent) -> CD data
* DVD: laser -> side A -> CD (semi-transparent) -> DVD data
I don't know if early CD players can ignore the semi-transparent DVD layer in the middle of its optical path. -- Toytoy 00:20, Mar 22, 2005 (UTC)
:DualDisc is just a CD and DVD stuck together. It's similar to making a double sided DVD. The thickness is a compromise, and CD specs can't be met. Mirror Vax 18:28, 11 July 2005 (UTC)

message: I moved things around and fixed the wording in quite a bit of the criticisms section.  It seemed far too complicated to understand.  Hopefully I've made it a bit more straightforward. --192.223.226.6 16:59, 29 July 2005 (UTC)

message: Are there double sided cds, like two audio sides and no dvd side?  If so, are there double sided CDRs?  Are there even writable DualDiscs for PC writers yet?
: Just copy the CD side and burn to a CD-R and copy the DVD side to a DVD-R! It good cuz you can seperate the teo and have a real disc! RealG187 16:41, 12 January 2007 (UTC)

thread_title:  Below is a list of the "thirteen" initial DualDisc titles released as part of the test marketing. 

message: Are these still manufactured?  I can't find any releases after about 2006, did these cease to exist?  Am I just looking the wrong places?  Thanks for any help clearing this up, as it is not covered in the article.--Nokorola (talk) 16:21, 27 March 2011 (UTC)
