DiscImageStudio burns visible artwork directly onto CD, DVD and Blu-ray surfaces
DiscImageStudio: burn visible artwork onto CDs, DVDs and Blu-ray discs
DiscImageStudio converts an image into data that obeys the physical-layer constraints of CD, DVD and single-layer BD-R discs, so once burned, the artwork becomes visible to the naked eye on the disc surface. The Windows GUI handles design and burning, while an experimental CLI for Linux and macOS generates ISO, RAW or WAV+CUE images offline. Calibration sharpens the projected geometry, and instant burning is experimental, so use only sacrificial discs.
Compared with manual visual calibration, the assisted calibration algorithm raised the precision of determinable disc physical data from 10-6 to 10-14.

I made a CTF challenge for this year's BSidesSF CTF where players were given a CDDA audio file (just raw PCM samples) which when burned on a CD-RW would produce an image of the flag. (The idea was not for them to burn the audio, since they'd need to guess my exact CD-RW or else they wouldn't get an image readable enough to be useful. Instead they were supposed to invert the process in software and simulate what a burned disk would look like, in a way that let them adjust disk parameters rapidly until they had a readable image.)
The challenge took me a few weeks to make because "calibrating" a disk (determining the geometry of the pregroove) is incredibly sensitive.
After the CTF I tried really hard to make a repeatable calibration process with the intent of building something releasable. I even ended up measuring the details on every CD-RW and CD-R I could buy on Amazon.
But despite trying very hard, I never did make calibration patterns that were reliable enough that I felt like other people would be willing to go through the process.
It seems someone else has succeeded where I failed. Great to see!

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.

Is it just me or do other find anime girls plastered all over a project kind of off-putting?

I've always wondered if this could be used to create 3d holograms.
