All Optical media (CD, DVD, Blu-Ray etc.) have pits and lands. These are microscopic and represent the binary information of the data stored on the disc. A land is reflective and reflects the laser into a sensor to register it as a I, but when the light hits a pit, it shatters and no reflection is received, thus a O is registered. There is much confusion as to which is a pit and which is a land, even some professional texts get it wrong, but this is the way I was educated.
