Yeah, that was what I was thinking: A side for digial, B side for analog. I mean, aside from the whole diameter thing, of course.

Flip-side (heh): haven't they also come up with optical readers for vinyl? Expensive af, iirc, but it's a thing?

@cavyherd @uint8_t pretty hard to do with a regular CD cause the aluminium coating is directly on the top, together with the laquer and printing, Would probably work better with a double sided DVD since they have the aluminium coating sandwiched on the inside

I thought the aluminum coating was *inside* the plastic shell? Maybe it's the double-sided ones I'm thinking of. (It may be apparent that I've never looked closely at CDs.)

@cavyherd for a CD the coating is on top, covered by a thin layer of lacquer. For DVD's it's sandwiched between two thin plastic disks

Oh how interesting! I hadn't realized there was any structural difference at all.

@cavyherd Used to be a long time ago! But then it was cheaper to not double-side it.

@cavyherd @slyka @miunau there are of course laser readers for vinyl discs. the issue with it is dust; the needle can remove some dust from the groove, laser can only do it at significantly higher power levels 😉

Oh. Dust. Right. Which tend to, uh, alter the vinyl, ahem. Interesting. I would expect some degree of algorithmic correction could address that?

Probably too late in the game/too low volume to be worth it, but I'm a little surpised no one's come up with non-static vinyl.

Dust? You just need a huge noisy compressor, some tubing and a jet just before the laser to clean the groove. Add some water with surficant to the air jet too, perfect.

😂 👍

Or just vacuum pack the whole business.
