I have a LightScribe compatible external CD/DVD burner. It came with a LightScribe disc that I haven’t taken the plastic off still to this day. Since it only came with a single one I could never decide which one thing to use that one LightScribe disc for, back when I was still burning things on CD and DVD.
You didn't miss much. It took 20-30 minutes each pass, plus the extra cost for the discs.
But even if you were fine with that, it came out too light under actual lighting conditions, even after you burned it twice, which defeats the use case of making it look professionally labeled. For home use, a Sharpie beat it in every way.
Huh, that wasn't my experience. I mean, it absolutely was slow especially with sufficiently complex labels, but they generally came out fine. Granted, you absolutely couldn't just drop any arbitrary image into the LightScribe software and have it come out looking good, you'd have to mess with the contrast, but black-and-white text and line art would come out fine. And more legible than Sharpie, with my handwriting.
I used to have a label system called Neato, which provided round CD labels you could make on a printer, along with a tool to press them accurately onto the non-recording side of a CD-R. There were even transparent labels, so the resulting disk looked like a commercially produced disk.
I can't comment on this particular project, but I know that similar projects have allowed adding images to the unused portions of the disc. A given region of the disc cannot be both image and data, but the disc can contain an inner region of data and imagery in the outer unused portion.
DVD codec probably allows for a certain amount of error correction to recover from scratches, images can still look readable to humans despite a bit of noise, I wonder if there’s enough overlap there to meet in the middle and have an image that also stores data

I wonder if the disk can still hold data at the same time.
