This is a really clever idea, burn images along with the data on a CDR… Instructable maker Argon writes – “By carefully choosing the right 1s and 0s to burn to a CD, it is possible to burn visible images on normal CD-Rs. These images rely on the fact that the 1s and 0s created by pits in the CDs surface reflect light differently.” Link.

My old CD burner (Yamaha CRWf1) had a feature that would let you burn whatever you wanted onto the unused portion of a CD. the easieit things to see would be checkerboard style images but most anything was possible
thats insane, i had that idea yesterday!
Good old memories of CD T@2.
a.k.a. “Lightscribe”?
This technology has been around since at least 2004, but I agree that it is a creative use of dead space and the optical properties of recordable disks.
“LightScribe Direct Disc Labeling” is the full name of the commercial product that incorporates the idea of utilizing the unwritten portions of a disk for labeling via the arrangement of “pits”. I believe the patent itself is owned by HP; it is licensed to the various drive makers who, as I understand it, embed it into the firmware.
Lightscribe is a bit different. that etches images on the face of the disks. Similar methods to do it though
