Fun facts
- This format used a special stylus and high-density groove system similar to audio phonograph records; the discs were stored in a caddy from which the disc would be extracted by the playback device
- This format was cheaper to produce, both the player and discs, than the leading home video product at the time (VHS), but the discs would wear down more rapidly with repeat playback
- Although originally designed in 1964, this format did not make it to market until 1981, where it was already obsolete compared to the VHS, BetaMax, and LaserDisc
