The LaserDisc or Laserisc (LD) was the first commercial optical disc storage medium. The laserdisc has great storage capacity, but limited backup-medium capacity; primarily, this technology was an expensive, high quality home video format. The laserdisc was commercialised under these brand names: Reflective Optical Videodisc, Laser Videodisc, Disco-Vision, DiscoVision, and MCA DiscoVision.
