Re:Slight Change in Size? (Score 1)

Backwards compatibility on my DVD drive allows me to read CDs, but not only because they're the same standard size. The mini CDs (for example, three inch ones), used for promotional purposes and such, read just beautifully in most drives, regardless of their smaller size. In the same way, an HVD drive would theoretically read not only larger HVDs, but also the slightly smaller CD/DVDs as well.
