The tape formats are listed with Obsolescence Ratings as follows:
Extinct: Only one or two playback machines may exist at specialist laboratories. The tape itself is more than 20 years old.
Critically endangered: There is a small population of aging playback machinery, with no or little engineering or manufacturing support. Anecdotal evidence indicates that there are fewer working machine-hours than total population of tapes. Tapes may range in age from 40 years to 10 years.
Endangered: The machine population may be robust, but the manufacture of the machinery has stopped. Manufacturing support for the machines and the tapes becomes unavailable. The tapes are often less expensive, and more vulnerable to deterioration.
Threatened: The playback machines are available; however, either the tape format itself is unstable or has less integrity than other available formats, or it is known that a more popular or updated format will be replacing this one in a short period of time.
Vulnerable: This is a current but highly proprietary format.
Lower risk: This format will be in use over the next five years (1998-2002).
Interesting that something which will be around for five years is considered to be a format with a future. U-matic managed about thirty years, and Quad over twenty. Even Super-8 film, one of the most recent formats, has managed to survive for 40 years, and IMAX is now 35.

Tim Stoffel who runs Quadraplex park in Reno has quite the massive collection. Playing with the quads is quite a feat in itself-kinda like running changeover 70mm machines: just something you'll never forget.
One should check out the Yahoo VTR and AMPEX forums and talk with these old VTR "tape handlers", for a bunch of them are just like us "film handlers" in FT - perfectionists in their trade.
There is one format that was left out in that one site, and that is the 1/4" inch open reel format.
AKAI originated the 1/4" inch reel format for portable use. The tape, even though looks like regular audio tape but of the difference being of the highly polished CR02 oxide surface as we see with the VHS/Beta tapes. If one used audio tapes in these machines, quality will be much lower and the rotating heads will definitely suffer of quick wear due to the coarseness of the oxide base of the audio tape.
Here are two picts of the 1/4" reel format. One of them is my Roberts 1000 in video mode and the other showing the only two AKAI/Roberts 1/4"inch home deck machines: The one on the left is the AKAI VT-700, and the right is the Roberts 1000(AKAI-VT500). the 1000 had a price tag of over $1300.00 with a B/W camera and a special BW TV/monitor, since the unit could only be hooked up to a monitor by a special 8-pin video baseband cable. Being a quarter inch tape, thes AKAI's weren't part of the EIAJ forum being of a special format.

...and also, there is the extinct "VX" format of Quasar/Panasonic of the mid-70's.
This is my first VCR, the VR-1000 "the Great Time Machine" that I purchased back in the summer of 1977. Thing weighs in at 45 lbs and the 2hr tapes had a $34.99 price tag on the box.

One has to do a search on the Cartrivision concept. It was a beginning of an idea that never took off commerically.

I've used an Akai quarter inch portable; I didn't know that they made non-portable versions.
I can think of quite a few other formats, there was the Grundig SVR system, based on the Philips 1500 and 1700 series, but with the playing time extended further. Then there was the Sony CV2100ACE half inch machine, which were widely used in London schools in the '70s, similar to the EIAJ machines, but the oxide was different, and the tape ran faster, 11.5 ips. There was a PAL colour wersion, the CV5600P, but I never saw any mention of an NTSC varient. These machines could record both the 625 line and 405 line standards, though I doubt if many of them ever did 405. I did make a recording from a 405 line signal once, just to try it. The longest tape which Sony made for these machines was the V-32, which ran 40 minutes, and cost over twenty pounds, a lot of money in the early '70s. 3M made a 60 minute tape, but it was on a thinner base, and sometimes caused problems. Sony also made an endless loop tape, which ran about five minutes I think. It was similar to an 8-track audio cartridge, but a length of tape had to be pulled out and threaded through the machine. The lubricant drom the back of the tape found its way onto the heads, and the thing generally jammed after it had run through few times.
I quite liked the Philips V2000 system; it was better than VHS, but was introduced too late.
Somebody, I think it was National, before they teamed up with Panasonic, made a 2/3 inch machine, which took a cartridge with only one spool; the take-up spool was permanently fixed in the machine.
Formats I've used, in some cases only once, and a long time ago:
Sony CV2100
Half inch EIAJ
One inch Ampex
One inch IVC
Quarter inch Akai
Philips LDL-1001 half inch reel to reel
Philips 1500
Philips 1700
Philips V2000
One inch 'C' format
Two inch Quad (at the very little used half speed version)
Two inch IVC 9000
Betamax
VHS
U-Matic
M-II
Betacam (Original oxide version and SP)
Video 8
I'm yet to get my hands on any digital format. The media department at the college where I work uses DV-Cam, but I've never used it.
