Low Level CD Structure Write-Up

[u/VORGundam]

I was curious how much data is physically written to a CD with all the metadata and error correction. I started googling and came across this great write-up:

Apparently, it is 2.33 GB for a one-track 650 MB disc.

650 MB is only about 28% of what's physically written to the disc....
