Few people even remember that such a medium as vinyl movies existed, but for a brief, doomed period in the early 1980s, home video was available on CEDs. While CED players were not released to consumers until 1981, the development of the system dates back to the 1960s. The idea was that they could encode sound and video information to a vinyl disc if they could only get the grooves small enough.
Fascinating. I had no idea they ever tried to do this. Better yet, that they succeeded.
CEDs are not “vinyl” in that sense; it’s like saying DVD’s are CD’s because they both use a polycarbonate substrate.
They are fascinating though; CED magic is worth a read (and I’ll put in a plug for the Colour Recovery Working Group: https://colour-recovery.wikispaces.com/ The stuff under “Previous Work” and “Current Work” is fascinating)
