- Similarities of CDs and DVDs. On the face of it, CDs and DVDs look very much alike. Both have a standard 12 cm diameter, and both are about 1.2 mm thick. What's even more important is that they are both optical discs, which means that the data stored on them is read by a laser. The laser goes over the pits and lands embedded onto the disc surface, and communicates a signal to the reading device that turns it into a digital code of 1s and 0s.
