CD, DVD, and Blu-Ray (Not PHP)

Hi gang: I'm no expert on media, but the only difference between CD, DVD, Blu-Ray is the amount of data they can hold, right? IOW, you can still record video, audio, pictures, files, all digital data on all media - it's just that Blu-Ray can hold more than DVD and DVD holds more than CD, isn't that right?
