Looking at snippets of disc production, it's no wonder the discs produced by DiscoVision tended to be finicky. Creation of the glass master, electroforming of the molds, and plastic disc replication were all done without the use of clean rooms. No matter how hard they try to keep everything clean, they can't keep it clean enough. I also remember a story about when Pioneer began disc replication in Japan. There were DiscoVision engineers present during Pioneer's testing of their facilities. Basically, the DiscoVision people made fun of Pioneer for taking all those precautions ... then the DiscoVision people saw the result: Pioneer was producing superior yields.

I wish somebody would write a book about the history of laserdisc from its development to its initial sale to its relative 15 years as a sizable niche in home video, but one big enough to justify pushing the envelope for technical presentation, to its rapid end once DVD came along. The Internet has tried to call it a failure despite it holding on two decades, but it is easier to make that argument about CED when that spent more time in development than it did on store shelves.

"Drop outs - missing lines of video information - are usually caused by missing pits. This phenomenon can be caused by either a faulty or worn master, dirt, dust or other contaminants infiltrating the manufacturing process. Because of the somewhat elastic perimeters for clean room status at the DiscoVision plant, it is not uncommon to see finger prints, human hair, insect parts or other foreign objects actually imbedded below the surface of a disc. Freshly pressed sides that passed quality control were checked with a felt pen mark on the back of the disc before it was sent along to be bonded into a two sided disc. On many early pressings the ink in the pens used eventually ate through the plastic coating of the back of the disk, showing up as large black V's through the reflective coating." *V* for DiscoVision!

The narrator is actor Joseph Campanella.

You can even see artifacts of DiscoVision rot on this disc showing how shoddily they were made!

Hey you are lucky! Those DiscoVision Discs were not pressed in a dust-free environment in that time so many discs did not play at all, skipped or had ugly reading artifacts (like the speckles in your video, too). It took some time for them to realize that the pits are smaller than a typical dust particle and enclosed dust makes a disc rapidly unusable. AFAIK IBM gave them the hint and pressed usable discs after. That was one reason of the failure, despite the high cost and the low reliability of the HeNe laser tubes (the laser diode was not invented yet) - the amount of non playable discs was way too big and customers returned them.

_"Those DiscoVision Discs were not pressed in a dust-free environment in that time so many discs did not play at all, skipped or had ugly reading artifacts (like the speckles in your video, too)."_ All of that happened because MCA apparently tried to keep production costs down, equivalent to the cost of producing vinyl records, ignoring the engineering recommendations of producing discs in a clean room environment. It also didn't help that the building MCA used to make the discs in Carson, CA. was formerly a furniture factory. That meant converting any portion of the interior into a clean room environment would prove to be a futile attempt. This was because of the sawdust and other contaminants that were present which could make their way to the production line no matter what you tried to do to stop it. If I recall, when Pioneer took it over, the old building was razed and a new facility specifically designed for the production of optical discs was erected in its place.

The LaserDisc was created in the same way DVDs and CDs are made today.

That movie didn't reach laserdisc until 1982 when they set it at its current running time of 128 minutes. Meanwhile, a lot of the titles Disney announced from the DiscoVision deal never actually got released by DiscoVision. *The One and Only Genuine Original Family Band* was one of them, and that made it to an in-house Disney laserdisc around the same time. Goldie Hawn's presence in the film probably helped get it released when it was since her movie career that this movie started was on an upswing thanks to her movies with Chevy Chase.

I know you're referring to the blue laser used in disc mastering in this vid, but in terms of quality at the time, yeah. LaserDisc was kind of the bluray of its time with a larger resolutions than vhs and betamax. Of course, in its early years, the manufacturing was pretty faulty and early laserdiscs suffers from laser rot making the picture grainy, like in this vid for instance. See the horizontal specs flashing on the screen? Those likely wouldn't have been there when the demo disc was first shown to the public.

I just did the math, and by my calculations each disc can hold about 1.6 GigaBytes of data on each side. Not bad for 1978 tech. It would be interesting to watch this video without the digital compression artifacts.

At 5:12, it looks like they're using an IVC 9000 2" helical VTR for master tape playback--this surprises me, for I thought DiscoVision used 1" Type C for their mastering source for discs at the time. Then again, the 9000 had the best video quality of any videotape format then, so I assume they wanted the best video quality possible. The 9000 was legendary for its time for its quality--many a network TV series in the era like "Barney Miller" were produced on 9000s.

@happycube

Yup, they used the IVC 9000 in the first couple of years, until they had to interoperate with other houses - and IVC itself went out of business, so it became impossible to even reuse the 2" tapes for later CAV disks and the CLV remasterings, unfortunately.

Actually there are parts of the video program for this laserdisc that was shot on film stock, then developed, and then telecined onto video tape like Type C. It is then recorded back into this video disc.

At 6:54 I'm sure it's a CAV laser disc because I can see those fine vertical lines which are horizontal sync and the two larger lines opposite to each other are vertical sync which are not visible on a CLV laser disc.

@prfo5554 that was a factor, certainly, but the biggest problem at RCA in the 70s is that they got into too many noncore businesses, and the core businesses suffered as a result because they were neglected. They bought a frozen food company, a greeting card company, a rental car company, and a carpet manufacturer. And as a result, CED missed the boat when it could have gotten there first. If times have been better economically, that also might've helped increase the number of people adopting home video sooner than they did. What RCA did then is just like what Disney is doing now, which makes it a coincidence that that was the last full decade of *Wonderful World of Disney* being on NBC on Sunday night. The studio asked the network to put them on another night, but they refused. They wanted Wednesday, but NBC put *Real People* there. *Disney's Wonderful World* as a lead-in to *Diff'rent Strokes, Hello, Larry,* and *SNL* reruns might have been interesting just to see whether more or fewer viewers tuned in than did with *Real People* as a lead-in. *Hello, Larry* turned out to be the weak link in the schedule they went with, hence *the Facts of Life* taking its place next season. How *Real People* would have done against *60 Minutes* is anybody's guess. If it flopped, then at least we would've spared the rest of the dumpster fires reality TV enabled. But nothing could beat CBS, not even from the same production company producing NBC's only sitcom hits until Nell Carter got a show (with more time slots than seasons). A few years later, under Brandon Tartikoff and Grant Tinker, *Silver Spoons* did better on Saturday than Sunday. Even after they moved it to the death slot, a special Saturday night broadcast between *The Facts of Life* and *The Golden Girls* about four days before Christmas 1985 saw its ratings go up four points. They didn't even want to try *Punky Brewster* on another night because if it was on too late for young children, they would be in bed before it was on. But under Fred Silverman, if Disney could have done better on Wednesday than Sunday, it might also have benefitted from having the two aforementioned youth-oriented sitcoms after it. And it wouldn't be at the mercy of football, so it wouldn't keep getting pre-empted on the East Coast.
