CD versus DVD - Dimensions of substrates and data layers

I need an up close depiction of how a CD differs from a DVD. I know the DVD has two .6 mm substrates, but how thick is the recording layer? And I know the CD has one substrate, but what about the thickness of its recording layer? I just want to be able to show the differences, with dimensions of each disc side by side. Anyone have a good site for this? Any tips. Thanks in advance.

Try to do some search in google you may find some technical publication on this issue.

Transferring to ‘Optical Storage Technology Technical Discussions’; I’m sure you’ll get a good answer there…

There is a very nice technical diagram of CD physics in this post
