Rodan on CED (Capacitance Electronic Disc)!

Poor Rodan always seems to end up being the subject of some of my weirdest posts.



"What is this thing that kind of looks like a giant floppy disc?" You might ask. This is a CED, or Capacitance Electronic Disc, which I'm continually having to resist calling a "CED disc" because that's like saying "ATM machine". For a better summary of what it is and what it does, check out Techmoan's video, which includes a teardown of a CED machine (or three). For a full list of titles released to the U.S. market on CED, see here. For the U.K. market, see here. (Rodan is listed as "Uncommon", and was not released in the U.K.)

In short: it's a dead format several decades and millions of dollars in the making that turned out to be, as one YouTube commenter puts it, "a turkey". The actual video quality is not as bad as I expected - really no worse than some of the VHS tapes I've digitized - but the format has a quite unfortunate problem with stuttering and skipping, rendering a lot of movies flat-out unwatchable. More titles were issued on CED than you may think despite its short lifespan, and the list of U.S. titles includes both Godzilla 1984 and Godzilla, King of the Monsters!. My copy of Rodan is from 1983 and I got it dirt cheap; I have no idea if it's watchable, and don't have any plans to invest in a secondhand CED player to find out. It's mostly just a novelty to display in my room.


We owe Rodan's existence on CED to Vestron Video, who in 1983 put the pedal to the metal and decided to release the movie on every format simultaneously: VHS, Betamax, CED and LaserDisc. Rodan was also issued separately in 1965 on Super 8 as a black-and-white "digest" version, which you can watch here. It's most just an action cut and honestly isn't that bad if you just want to see monster stuff; it's a testament to how good Rodan was that it holds up even in such a condensed format. (Hirata's in the Super 8 version, but only a little, and for some reason looks even nerdier in black-and-white than he did in the original.)


Techmoan's video mentions CED in both the U.S. and the U.K., but having a kaiju movie on this format got me wondering if the format had any lifespan to speak of in the Japanese market. Japan is very good at keeping unusual media formats alive much longer than the rest of the world (cf. Minidisc), so I wanted to do some research to find out if any CEDs ever made it over there.

Short answer: Japan knew about CED but said nah.

Longer, more accurate answer: Japan did want it - or at least some people did - but was too busy at the time with a format war going on between VHD (Video High Density), LaserDisc, and Germany's obscure TeD (Television Electronic Disc), and although Hitachi was looking at commercializing the format for the Japanese market, it ultimately never entered domestic production, and only existed within the country as direct imports by collectors. I'm getting my information from JP Wikipedia, which unfortunately lacks a citation for this particular chapter of RCA's history, so I can't give you sources beyond what's written on the wiki. For a more personal, less objective opinion, I'll cite this blog post, whose author seems to have been entirely unfamiliar with CED. I wouldn't take one blog post as representative of the entire populace's knowledge of CED, though, and it's also worth pointing out that most people in the U.S. and U.K. - CED's actual target markets - probably have never heard of it either.

However, and more interestingly, I also turned up this article in Japanese, which is a pretty comprehensive look at what a CED was and how the format works. It's dated to 1982, so CED was still extant at the moment, although moribund; I don't know why somebody would have gone through the trouble of producing a Japanese-language guide to the format if there was not at least some interest in it within the country. This, also in Japanese, mentions CED as well, but only to make a brief note of its fleeting existence.

So that's some Rodan miscellany for you.
