This article is from the RCA SelectaVision VideoDisc FAQ, by tom@cedmagic.com (Tom Howe) with numerous contributions by others.

1.14 Grooved records containing images and sounds of Earth were placedon the two NASA Voyager spacecraft launched in 1977. Were these CED's?

The Voyager records were not CED's but gold-plated Audio LP mothers made
of copper, which normally would be used to make stamping molds for vinyl
LP's. The records were specially mastered to spin at just 16 2/3 RPM and
needed several seconds to play back each still image. Playback directions
and a stylus cartridge were included with the records. RCA was involved
with the production of the Voyager records, and the image reconstruction
uses multiple scan lines similar to television. More details on the
Voyager Interstellar Record can be found at the CED Magic web site listed
in the header of this FAQ.
