Well, I'll be darned! I was wrong. That's really interesting... So, only factory CDs use pits from master dyes but CDs from CD burners use dye. Interesting... Thanks for the heads up!
Actually, you might be right (or right in the wrong way)...I'm not sure what the dye is and will look it up but since there is a change in the opaqueness of the dye, that implies that there is indeed a chemical change when energy is applied, and therefore a potential change in mass, albeit a tiny, tiny one...but still a likely necessary one?
