Description: CED VideoDisc The Bridge on the River Kwai (1982), Columbia Pictures Part 1/2 Good Condition, CEDs Have Some Wear, Some Writing on the Cases, CEDs Were Not Tested (See Pics) CED stands for Capacitance Electronic Disc, which refers to the method used to encode the video and audio information on the disc surface. Capacitance can be defined as the ability of two adjacent conductors to store electric charge, and in the CED system these adjacent conductors are the carbon-loaded disc and the thin titanium electrode deposited on the diamond stylus. The mathematical formula for capacitance contains several variables, but with the CED system these variables are all nearly constant except one-- the distance between the electrode and the surface of the disc immediately under it. Within the grooves on the disc surface are microscopic peaks and valleys, several times smaller than the diamond stylus, which rides smoothly on the crests of several adjacent peaks. But the electrode is much smaller than the stylus, so the distance between the electrode and disc surface is constantly changing as peaks and valleys pass underneath. This varying distance produces a varying capacitance, from which the audio/video signals are eventually decoded by the player's signal processing circuitry.
