i don't remember if these were ever widely released, but do dual-sided CD/DVD combo discs exist in a writable format?

@xenon dual-sided cd/dvd combos aren't allowed by the spec and iwrc are actually slightly out of spec so some players won't read them, so i would be surprised if writeable ones exist. they might though

@Felthry oh, that's too bad. physical media that's able to carry audio and videos as two separate pieces of an art project would've be nice

@xenon I think it should work fine? Each track written to a CD is handled separately, and can be different types of data
and playing it back wouldn't be hard if you were worried about that, by the way. Just about any DVD player can play video CDs, even if that's not a feature most people use outside of southeast asia (where VCDs were much more popular than videocassettes due to better resisting that region's humidity, and where they continue to be a popular low-cost format)

@Felthry i'm actually trying to rip one of those CD/DVD combo discs for archival right now, and our computers seems to recognize it as a video CD rather than a DVD

@xenon It may actually be a video cd then? if it's reading fine as a video cd it's definitely not a dvd
-F
@xenon pretty sure DVDs need the laser focused differently, the depth of the data pressed into the disc is different than a CD
-F
@Felthry that's interesting. i'm not sure why the publisher would've put "DVD" on it then, unless they thought labeling it as "video CD" would be an issue somehow

@xenon video CDs are almost unheard of in Western markets, but everyone knows what a dvd is, perhaps?
-F
@xenon VCD didn't really catch on because it was the same quality as a VHS but you needed new equipment to play them
-F
@xenon There is also DVD audio, though i'm not sure how many things work for that
-F
@Felthry i'm sure it would be possible, but i'm not sure how well software supports disc burning outside of one or the other
