lol, Yes, the label side.
No these are 16x discs, and the color is copper, not the bright yellow/gold of the 4x and -RWs discs Maxell sold.
Here's what it looks like.
Never thought of trying to wipe them off-I'd rubbed my fingers across once to see if it smeared, but when it didn't and nothing appeared on my fingers, I just assumed those were going bad. Some were kept in individual dvd cases, and a few were in spindles. The cloudy ones in the spindle didn't leave anything on the bottom of the burned disc that was on top of it, plus I handle my discs carefully so I didn't think it was due to grease from touching them on the top. Those photos don't show how faded the cloudy ones (Space 1999) looks verses the normal (Starship Troopers) disc color.
Thanks for the suggestion though. .
If you could add a date, at least year, in your orig. post, that would provide one more anecdotal piece of info in the "How long will my discs last?" question... at least in regards to the 2nd tier discs.
DVD Identifier shows mine to be Prodisc F02
Outgassing from plastic cases/sleeves?
