Consumer electronics: Video disks: Three choices: Three incompatible approaches to video recording for playback are compared

Compares three commercial video disc systems, two of which are available and one of which is still under development. The three systems are incompatible. They are: an optical pick-up system (Laser Vision), a capacitance electronic disc (CED), and a video high-density disc system (VHD) to be introduced later in 1982.
