The optical disc is a form of technology that first emerged in the late 1970s and progressively developed throughout the 80s and early 90s. The optical disc consists of a round plastic disc encoded with data through the use of pits on the disc's surface which are read by an infrared laser. The laserdisc, the first iteration of the optical disc format, was capable of audio and video playback through analog encoding. Subsequent iterations of first generation discs were capable of digital playback, but without the ability for video playback.
