I worked at DiscoVision in Carson CA 1981 and we had more rejects than good pressings. quality control was difficult. We would actually play a clear disc directly from the mold presser and determine if the master was defective. from there the clear disc went to the metalizing dept to have the coating baked on. after that the two sides were glued together. another quality control check was done to view the finished disc. hundreds of rejected disc were discarded daily.
For me, the Holy Grail of dead sides would be the copy of Jesus Christ Superstar with footage from the unreleased Andromeda Strain disc.
OK!
Or visa versa.
The "P5" error means the disc isn't coded to the laserdisc standards and is likely a General Motors disc. It will play on players made before 1995 or so, or on any later Pioneer player if you have the service remote to put it in Test mode. What model player are you using?
I've been uncovering these sides for over 20 years, I use a TON of paper towels and let them SOAK in the rubbing alcohol. It gets easier over time. I ruined one disc using alcohol that was too strong and put a crack in it, better to use the weaker stuff and go over the disc more than once with it if you have to. Most important part to clean is the center so the player can recognize the disc and start playing.
I'll have to try it on my 1987 Pioneer after I move. It did have some (existing) clouding on that disc, so it may just be a lost cause.
Born and raised in Detroit, I run across these G.M. discs at flea markets all the time.
Also I wonder if a pre 1980 LD player like the OLD Pioneer with an HeNe laser instead of the semiconductor LED system would punch through? Those could play really bad discs better than the LED systems could. More power I guess?
The top-loading players are actually better with old discs than the later players. I keep a few around just for them.
Exactly! The top loaders like the Pioneer (no Magnavox they just had too many problems) did indeed handle poorer quality discs. I know they went to the laser diode due to cost, and for the most part they did their job. But those old top loading tanks, they really were well built!!
I think some of the industrial discs only worked on certain players. Maybe the Tom Sawyer disc would play in a really old machine.
My favorite dead side will always be the turtle.
Ben mentioned some clouding on the disc he couldn't remove. What most likely happened was that the previous owner who attempted this didn't dry out the rubbing alcohol quickly enough, thus clouding out the disc. It's unfortunate, but I doubt that even a fully restored PR-7820 would be able to play it.
IMO a high end machine may be still able to play it, but we'll probably never know.
BTW, what Turtle?
Search for "laserdisc turtle."
Some industrial discs used MCA coding for player control. Consumer players will not play MCA coded discs since they are made to comply with the LaserVision standard, which uses Philips coding.
That said, it's possible that the dead side which wouldn't play may also not play on a machine that can work with MCA coding or a player that doesn't pay attention to any control codes at all, such as the Pioneer LD-660.
The Pioneer player that was used to attempt playback threw a P5 error code, indicating that the player couldn't read any signal off of the disc. In the case of a dead side, this may be a sign of a defective pressing that was so bad that it wouldn't play at all.
In the case of a good MCA coded disc, the same player would be able to lock onto the track, but would abort playback after about 5-10 seconds because it couldn't read a control code it could recognize when trying to read the TOC. An error code would be invoked, but it wouldn't be a P5 since the player could read a signal off of the disc but couldn't detect a recognizable control code.
The GM discs were designed for the PR-7820 player. Some older players will be able to play the disc, but without trick play functionality.
This was a very good video. When I saw disco-vision I thought it was all disco music video things until I remembered back to you talking about disc-o-vision if even for a second in a past video.
I have some Donald duck disc . It was purchased from Video Concepts in Dallas.
Scott Strang That's awesome! I'd love to own at least one of each the more widely available video and audio formats for myself when I start work in the fall!
Those covers are well and truly hideous. I get wanting branding, but like 66% of the cover is branding with only a fraction showing what the actual program is. Geez, MCA.
It's supposed to resemble a leisure suit.
On some of them, the program graphic on the front and info on the top / back is a big sticker that was stuck to the box. This is the case with my copy of Airport '77 on DiscoVision.
RCA had a better idea with fitting the center of a film poster inside a big circle.
The whole thing is weird.
From the Spirograph deal at the very beginning to the busy "in case you didn't see it on the case" discovision intro, the format branding is a train wreck... Even to the point I keep rewinding to watch it.
By the looks of it, the previous person who attempted to uncover the dead side of Tom Sawyer did indeed half-ass it, as they didn't try to clean up after themselves, allowing the rubbing alcohol to cloud out the disc (which will happen if they don't dry it out before it's too late). The clouding is unremovable, unfortunately.
My DiscoVision copy of 1941 has side 2 of Animal House on it's dead side. It's a very interesting part of DiscoVision collecting as you'll never really know what's on the dead side until you check it out.
It has an it is dead side?
I have no idea WHY I find your videos so GOD DAMN interesting! Keep up the great work.
the sped-up intro sounded like it had some happy hamsters in it...
Or Ed might have had a Red Bull before rolling the intro. 🤣
Something about this episode left me feelin' groovy.
It's what all the kids are listening to these days. They sure like that jazzed up be bopping music.
@@dougbennett8592 Wow, I don’t know if you’re pretending to be a senior or if you are an actual senior.
Well, fancy that!
The "KOOL-AID, KOOL-AID" theme was actually sped up for this one.
I remember when I had laser discs & the other side was blank, I remember seeing an animated turtle on its shell & it said turn over disc or something like that. I don't remember if the disc's were Discovision or the regular variety.
That was Pioneer's standard dead side, starting in 1981 til the end of the format.
Wow. Great episode. There’s a certain something about laserdiscs that give me some nostalgic brain tug. Hope the move is going well.
11:53
A P5 error code on your newer Pioneer player means that the player couldn't sense a signal off of the disc for whatever reason, so it couldn't close the servo loop and begin playback.
Most likely reasons:
1. You didn't clean off all of the residue on the dead side; you cleaned off enough for the player to sense the disc, but not enough for the optical servo to lock onto a track and close the servo loop to play the disc.
2. A defective pressing that was so bad that it can't be played, which would explain why it was rejected and repurposed as a dead side. It's important to note that not all DiscoVision dead sides are playable.
or maybe it was the half-assed clouding...
@@imrustyokay Well, if the clouding is still preventing the disc from being played as intended by DiscoVision despite the effort to clean it off, then it's hardly half-assed. Just saying.
Far out man, dead side mandalas.
Nice use of those 60s pop instrumentals from the "Vinyl Potpourri" episode during the cleaning sequences!
Those graphics on "The Touch Of Love" dead side look like they were done with a Spirograph...
Well, you bet that I am interested! How do I get better at tennis in just thirty minutes?
Oh, bite me... what now? Oh, oddity archive made a new video :D
10:15 "Slow down, you move too fast..." I see what u did there.
In a hurry for the opener are we Ben? Love hearing 'bout the info on these 'dead sides'. I have 2, yet to try this removal method...
12:57 Let's all hope D*sney won't mind this.
Or, D----y.

The footage from that uncovered Jaws side looks better than my actual discovision Jaws set (which coincidentally, still has the lacquer on the 3rd disc)
I actually have a couple of Discovision discs. Will have to try this!
coming back to this ten months later... yeah, those discovision "next side" bumpers still kinda give me the creeps
lol
"The Touch of Love" is one that I have in my collection. I believe it's possible to find different programs on the dead sides of some titles. I'd have to check but I believe the dead side of my copy of "The Touch of Love" has one of the sides of "Psycho." Everything plays perfectly except near the end of the dead side, which has laser lock. I have the spyrograph style logo on several DiscoVision titles.
Wow that's fascinating stuff
I sometimes use the dead side to set my anti-skate on my turntable.
There were several "Dead Side" discs with GM Training courses . Look on YT "1978 Chevrolet Pro Serv Training 'Just a Little Misunderstanding' MCA DiscoVision" It was found on the third disc of "The Choirboys" ...
I remember in the early 1990's, how they used this format for Karaoke.
"Massage area"... is that what the kids are calling it these days?
I recently managed to get hold of a copy of the DiscoVision version of' Frenzy' for £10. Side 6 is the same 'Jaws' side as the Tennis disc. I think that this set was recalled because of a manufacturing error on side 5, because every frame is encoded as a separate chapter stop making that side unplayable as you have to press play for every frame.
This wouldn't affect certain players, such as the LD-660, which doesn't care about control codes, or the VP-1000 with the frame counter disabled.
The fact that side 2 of a p*rnagraphic disc ended up being a donald duck cartoon is ironic
14:40 with auto generated subtitles on: essence of ninja clothes? What? 1970's softcore pron was weird.
LMAO the cover looks like a leisure suit! XD
12:17
Daleks...
I have a Dokken laserdisc with the white plastic.
seems youtube did not notify me that you uploaded, god damn it

i love how no one's mentioned that it says 'episode 150.5' twice in the title
It could be laser rot. It has to do with the glue when they put the layers together. I had a hard time finding a good copy of the Beatles Let it be movie. Most of them seem to have that problem. Bad sound and picture .
agree
Who would have decided to put content on the unusable side, or what to put there? Some rogue mastering engineer? Or was it an artifact of the manufacturing process somehow?
They needed two physical sides for the disc to work, so they just slapped on whatever was laying around.
Those were rejects or unreleased titles.
Oooh. You accidentally let a D***ey product come through.
*D----y
Of course it's D****y. Ben just can't escape.
Well well well .......
It's the system, they also called "Laserdisc", picture and sound is in FM, later discs had digital sound too.
What Song Is Called From 8:41-9:11 To 9:24-9:38,OddityArchive?
What Song Is Called From 10:07 To 11:23,OddityArchive?
So they obviously allowed porn on that format...! (Also 8:55 -- great Ceefax music!)
Ha! Musak Feelin' Groovy! How marvelously cheesy.
I was feeling groovy! Felt like I was on aisle 5 looking for the General Food's International Coffee
91% Isopropyl Alcohol can also clean moldy vhs tapes
Neat!
Bummer that the Tom Sawyer one didn't work. :/
Would a disc resurfacer work on this
It wouldn't fit. It would have to be a giant one, so it would fit a 12" disc (the same size as an LP).
Ther has to be some way to make our own laserdiscs, its just a double acrylic disc with tin foil in the middle, surely a laser printer and a router can make these.
Invest in a solid mic , otherwise enjoyable
What's the point of putting something on on the dead side.
It was cheaper to use rejects as dead sides and cover them in a lacquer.
@@und4287 exactly true. I worked at DiscoVision in Carson CA 1981 and we had more rejects than good pressings. quality control was difficult.
nightcore pavanned :P
The Discovision release of MLB: The Best of Baseball (side B) had American Girl: Isabelle Dances into the Spotlight
The Discovision release of NFL's Greatest Bloopers (side B) had a episode of Pokémon (Volcanic Panic)
The Discovision release of MLB: History of the Detroit Tigers (side B) had the PlayStation startup screen
The Discovision release of MLB: The 1978 World Series (side B) had Barbie and the Three Musketeers
The Discovision release of NHL: The 1976 Stanley Cup (side B) had a episode of SpongeBob SquarePants (Jellyfish Jam)
I'm not really laughing!
Discovision sucks!
Blu-ray! Blu-ray! Blu-ray!
