Burn images onto a CD, literally
Closed Published January 30th, 2006 in Noteworthy, PC, Shorts, Technology
Here I’ve shown a CD-R with a picture of two people kissing burned on it. It’s a little hard to discern because I haven’t completely calibrated this CD-R yet.
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. Data on a CD, or any optical media, is stored as a sequence of pits of varying lengths. To be precise, a 1 is represented by the change from pit to no-pit or the change from no-pit to pit, and a 0 is represented by no change in height (pit to pit or no-pit to no-pit). The pits and no-pits reflect different amounts of light; thus it is possible to draw images on CDs by appropriately arranging these 1s and 0s.
