AFAIK The reflective layer is on the top of the disc - where logos and graphics are. From the clean side you are looking at this metallic layer through the plastic.
- Balgair 6y agoHmmm, maybe there are differences between them. The DVDs and CDs that I have access to all acts as first surface mirrors (albeit not the best ones).
- CydeWeys 6y agoThe CDs I have access to are mostly burnt, not factory-pressed, and they don't have nicely mirrored surfaces at all :(
- CydeWeys 6y agoThere are no CDs/DVDs that are first surface mirrors. There is always a protective plastic layer on the outside, same as with any normal household mirror (except it might be glass in a household mirror; regardless, you will get internal reflections). This is the structure of a CD/DVD: https://cdn4.explainthatstuff.com/layer-structure-compact-disc.png https://cdn4.explainthatstuff.com/layer-structure-compact-di... I don't know where you got this idea from that CDs/DVDs can be first surface mirrors; they aren't. If they were they'd be really bad at their job, because one of the hallmarks of first surface mirrors is that they're incredibly fragile and do not stand up to any kind of handling whatsoever. That would not work for CDs/DVDs for obvious reasons. More info and diagrams here: https://www.clir.org/pubs/reports/pub121/sec3/ https://www.clir.org/pubs/reports/pub121/sec3/
- Balgair 6y agoI'm holding it in my hand right now. It's a DVD copy of Empire Strikes Back. It may not be a 'mirror', but the reflection starts right at the surface. Yes, it is rainbowy.
