Blu-ray DVD frontpage size

[tlmaclennan]

I'm not saying that we should be calling it Blu-ray DVD CD, but to say that Blu-ray, DVD, and CD are all entirely different is technically wrong. Yes they use different technologies to get more capacity on the same size disc allowing for more HD video and audio, but they are all still on the same type of disc. They are all on an optical disc storage medium, as Wikipedia points out.

Just because new and more efficient lasers are used doesn't mean the disc has changed much.
