https://doc.rero.ch/record/7958/files/StotzerS.pdf https://doc.rero.ch/record/7958/files/StotzerS.pdf is a PhD thesis for VisualAudio. It says "To get a good audio quality, a resolution of about 1 μm is needed, which would mean 25000 dpi."

Also, here's Heine's 1977 laser scanning phonograph paper - https://www.aes.org/e-lib/browse.cfm?elib=3098 https://www.aes.org/e-lib/browse.cfm?elib=3098 .
Here's a Saphir paper - https://hal.science/hal-01885324/ https://hal.science/hal-01885324/ .
Here's an approach using an off-the-shelf scanner - https://www.aes.org/e-lib/browse.cfm?elib=16071 https://www.aes.org/e-lib/browse.cfm?elib=16071 (the VisualAudio PhD thesis mentions these as having lower quality).
