Hello,

I recently bought a DVD disc, and it says that it is a double layer DVD disc.

What is a double layer DVD disc?

Its what it says it is. There are two layers of info on one side of the disc. The lasers can modify thier focus, or use a different wavelength to read that embedded data, cool eh? 3-D data storage.
