- Found this on the dead side of Slap Shot! From 1979 hosted by J. D. Cannon, this is how to use one of the first industrial laserdisc players. I don't have side 2 unfortunately since this was recovered from a movie's dead side.
anyone else here because this was sampled by Norse music maker, Anders Enger Jensen in his 2018 track DiscoVision?
Which was sampled from this upload.
I first thought it was Ronald Reagan. It's the same voice!
Yep, the song is great. I guess without this upload it wouldn’t exist, so thanks! 😃
Anyone else here because this was sampled by Norse music maker, Anders Enger Jenzen in his 2018 track DiscoVision, which was featured on a Technology Conndctions video?
@@oFFtheWall518 I think it was featured in two separate videos but whatever I don't want to be that pedantic
Anders Enger Jensen remixed this video in a song he called "DiscoVision."
Check it out; really nice track. 😊
That track is glorious.
That's why I'm here. I heard the DiscoVision song and was wondering where the voices were sampled from. It is a great track!
Anders song is great and it’s good fun playing spot the samples when watching this. Would make a good drinking game. :)

I finally got around to finish the video to my song, made from samples of this video:
ua-cam.com/video/Azsk21MpbUk/v-deo.html
Took a lot of editing and headbutting so much due to creativity. Wanted to do so many visual things I couldn’t do, due to lack of After Effects and 3D skills, but hopefully it’s good enough. 😁😎
Absolutely incredible track Anders, much appreciated ! :)
Amazing track, it actually led me here.
I heard your song in the Technology Connections channel. Great work! Reminds me of old MIDI and Amiga music.
Great track, like others it reversely led me to this video!
Love your song. 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.
D-d-d-d-discovision
The DiscoVision player gives you many special capabilities: stop, play, slow or in reverse
Imagine a dog chasing a rabbit around a tree
@@michaelramsey82 how can you get there in a hurry
How can you get there in a hurry?
Why would you need an instructional disc if you've got far enough to install, then play a disc? :D
They could've played this in stores too.
It's for amnesiacs
If it's not working, you will want to watch part 2, Troubleshooting.
I honestly never expected you to be in a Laserdisc world
it's a Dead Side, it wasn't meant to be seen dummy
Anybody else here because of Technology Connections? Then after because of Anders Enger Jensen??? Noo??
Ok
Almost. I’m here via Techmoan > Anders :)
Yes.
Yep. Been binge watching Technology Connections lately.
These old formats fascinate me.
I just can’t get my mind around as to why RCA would continue to develop and release the notorious CED two years after this film was made.
They really should’ve known better.
If I was around back then and had to choose, Laserdisc would have been hard to resist. It just had more features and was more advanced compared to CED even though that was much cheaper.
Anders Jensen made a song with this
How many of us are here as a result 🤣
Whoah, I had one of these! Over 15 years old at the time, but I got it as a gift from a friend who was a laserdisc enthusiast-it was his first player, but he'd since bought a more modern one and wanted to share the joy.
This thing was _brilliant_. First, as you can see starting at 2:01, you had to mount it on a spindle, which locked down with an audible _thwack_. But unfortunately the video doesn’t show you what's next: the top smoked plexiglass window let you see what was happening while the disc played. The laser pickup was stationary, the _spindle_ moved. (Which is why the thing is so _huge_; it had to have room within the chassis for the entire disc to move from edge to center.) Which mean you could look in and see the spindle and disc move, and you could actually _see_ the laser pickup!
Two funny things about this technological monstrosity: just as with every other home-movie technology ever developed, when this player was released there was a format war of sorts going. But compared to Beta/VHS, VideoCD/DVD, and Blu-ray/HD DVD the LaserDisc format war was relatively mundane, as far as format wars go. Since these discs were double-sided like a record (each side held up to 60 minutes, so most movies required a flip and sometimes a second disc), it was just a disagreement over which side was the "A" side and which the "B". Vendors who wanted to put the laser pickup beneath the disc wanted the "A" side "down", i.e., on the opposite side from the label reading "side A". Vendors who wanted the laser pickup above the disc wanted side "A" to be "up".
This poor thing was on the losing team, so when you played a commercial Laserdisc, you had to put it on the spindle with the "B" label up, then flip it halfway so the "A" label was up.
The other funny thing was a result of the moving-spindle design, which meant the disc spun freely without resting on a turntable, and spun _fast_ (at one rotation per video frame, 1800 rpm). If the disc was locked to the spindle incorrectly with a bit of a tilt (not easy, but possible to do on an old machine) this nearly 30-POUND hulk would start shaking, and could easily walk itself off a table if you weren't paying attention. Remarkably, despite containing a precision motor, not to mention a frigging _laser_, it kept running even after hitting the floor from a height of a few inches. This thing was a tank.
i have this player too. the whole thing about the reversed disc labels was actually deliberate and very simple. the PR-7820 has the laser sitting ABOVE the disc, unlike every other LD player. it's also the machine that most early industrial titles were designed to be played on. therefore, for those discs, the label is on the same side. all other discs have the label on the opposite side, because they're not specifically designed for the 7820. that's all it is. LD's with labels on the "wrong" side are meant to be played specifically on this machine, just as he says in the video.
Interesting stuff, thanks :)
J.D. Cannon had a real nice , cracking voice. Even if he whispered, everybody would still hear him, I suppose. ;)
Not to flex but John D Cannon is my Great Uncle! Can provide some receipts but I have limited info but I am a divergent of the cannon family!
Awesome! Do you have side 2 of this disc in your family's things?
Thought he was going to say "Hello, I'm Leonard Nimoy"
Leonard Nimoy at home
He sounds like him.
Progrum.
If George Burns and Leonard Nimoy had a baby...
Is it just me or does he look and sound a lot like Leonard Nimoy?
16:51
Doesn't your lad that's presenting it sound angry?
he's being stern and forceful. this player cost $3500 in 1979 money. you don't wanna break it!
Anders Enger Jensen thanks you
“High quality television”
Which is why we’re using a film camera with cheap stock to make this instructional guide.
Well, I guess parts 3 and 4 will forever remain a mystery. :(
Oh hello
Thank you for posting this. I picked up a player at a garage sale, working. This video is fantastic. I'm off to look for Part 2!
... you may have seen me in Cool Hand Luke, The Concorde Airport 79 and Death Wish II.
J.D. Cannon played the role of NYPD Chief Peter Clifford on the 'McCloud' TV series, which was part of the NBC Mystery Movie franchise!
An excellent actor.
He was also the man who witnessed Helen Kimball's murder on The Fugitive
What shocks me is that eject was called reject
yes
This video is historical and pure gold. Thanks for uploading.
Any that are still playable now should last forever. It was just the ones that rotted after a year or so that were problematic.
I can't believe such a wonderful device even existed 43 years ago. pure gold for those times
Here from DiscoVision by Anders Jensen
That track may not have existed without this upload!
Disco Vision? Is that another name for Saturday Night Fever?
+kxmode Pretty much what I thought. I guess they changed it in the 80s when disco died. XD
MadameSomnambule they renamed it pioneer laserdisc
That's the guy who freed Richard Kimball. 😉
The quality, for the age of the disc, is excellent. There is only occasional dot crawl, which is caused by artifacts on the disc substrate. I wish the dead sides of my discs had something useful like this. Some of them have test patterns for calibration, but mostly they say, "Please play other side". I like how he shows variable speed play and visible freeze frame. On the early players these features only worked on standard play discs (CAV), on long play discs (CLV), you would get gray or blue screens while pausing or scanning. Players sold in the very late 80's to early 90's had frame buffers for CLV discs that allowed these effects. Not as smooth, but it got the job done.
I also like how they use the word Reject instead of Park, Open, Remove or even Eject. This was in deference to automatic turntables that played vinyl LPs. When a tone arm on a record player reached the end grooves of an LP, it would automatically be "rejected" by the album and park itself.
Honestly, ANYTHING from a consumer video format from 1978 in this quality, especially DiscoVision which suffered from very common laser rot, is a miracle. Also, I am honestly not surprised that this was slipped to side 2 of "Chef", knowing MCA and their bad reputation with LDs.
The dot-crawl is more or less a problem with the fact laserdisc is a composite video format. Using a more modern digital TV with a 3d comb-filter gets rid of most of it. Most of the test patterns you see on dead-sides weren't for calibration...bur rather just to let you know there's nothing there. Each place that pressed discs had different ways of doingit. Pioneer discs had the turtle; most others had pretty generic looking text.
The blue-screen on CLV discs wasn't limited to just early players. Basically, a CAV disc contains two video fields each rotation; so all a player is doing when paused is displaying those two fields...on a CRT you get a frame...an LCD will give you god knows what. CLV discs however stored multiple frames per rotation; and only players with digital frame buffers could display a low-resolution still-image when paused. The fact is, freeze frame and variable speed play were only features on CAV discs. It was up to the player to to do trick-play features on CLV. None of them really got it right; and CLV discs...while standard...were always somewhat inferior to collectors.
Windows OS
thank god I got the Laservision series of MCA laserdiscs and not the discovision!
realgroovy24 tech Yeah. DiscoVision discs are now mainly for collecting.
Windows OS You seem like a passionate laserdisc collector I'm only beginning collecting laserdiscs so far I've got spartacus 1985 on MCA Laservision and I'm thinking of getting more of them
Somehow I knew he was going to pronounce it "progrum"
I just learn something I will never do XD ,,
Oh my god the discovision is a PS4
That's the general name given for any unused side of a laserdisc- the later discs had a message saying that there was nothing on that side, but the first DiscoVision discs had test pressings or whatever they had lying around slapped on, and they were coated with a substance to render them unplayable. However you can clean that off with alcohol- most of the time I've found sides of other movies and some General Motors discs.
Cool
it sounds like he's saying 'disca-vision'
6:25 On PC, you can actually practice step forward and step backward! Pause the video and press the > and < keys.
i love how he says "pro'grums"
This guy reminds me of Leornard Nimoy. Who also did a demonstration for a laser disc player.
He's a little bossy.
I owned one of these back in the 70's. It was quite the machine, before the advent of videotape.
What The Surfer Film Called?
How long has DiscoVision been around?
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.
The fact that the player can be *programmed* still blows me away. Harking back to an era when everything was hackable.
If they weren't programmable we wouldn't have the Laserdisc arcade games that we did.
Look up the "Sony LaserMax ViEWSystem LaserDisc Player LDP-2000 + Computer VIW-3020" its a mid 80s computer attached to a LD player
The funny part of this instruction video is: it is on a disc that must be inserted first to watch the first section "how to use (the player)". :-D Nice remote however why can you use also a cable? Just to add features? Nice unit anyway, want one just for historical reasons.
Also nice modularity - you can easily upgrade a remote in the future to add extra features. Not so with a front panel.
The capable is probably for issues with the battery, range, or line of sight. These old remotes could be really finicky, some may have preferred not to bother and just wire it up
0:15 You are getting sleepy...
Even a DiscoVision dead side looks better than your average CED 😬
I was waiting for that beat to drop
+kxmode DiscoVision is the name of the format. it was actually disc vision but they put the "o" to help say the name.
Someone find us side two
How did you remove the lacquer coating?
Lots of rubbing alcohol and lots of paper towels. There's a video on Oddity Archive showing how to do it. Anyone who has these discs should be obligated to see what's on the dead sides as it could be something rare like this.
After listening to a song using this video's audio it's interesting to hear the full audio, and also hard to not hear the song
This unit was built by Pioneer. It is so interesting that the disc moves and the the laser stays stationary. This is why you had to lock down the disc on the spindle.
4K is a little more advenced than this one.
4K is a resolution not a video format.
I was just about to upload the digitized version of this, and can confirm, the original was labeled as a single side (IP-7009). However, I got out the isopropyl and discovered the dead side (roughly 2" wide band) is a service pre-release for the '80 Chevy Citation!
I have the actual disc, but neither side will play on 2 different LD players. Side 2 just says "program material recorded on other side" and had the lacquar which I removed, and still nothing. So it has a dead side itself. Its actually weird as the outer half is mirrored unlike the recorded area
wow. my copy of Slap Shot has this dead side too. interesting coincidence. i thought DiscoVIsion dead sides were much more random than that.
progrim
He witnessed the murder of Helen Kimble (The Fugitive). Quite the character actor of the day.
DiscoVision...well I didn't see much disco here.
meanwhile I'm watching on an ultra-light notebook laptop and thinking that that was so new there
I recall only seeing a Laser Disc in a elementary school history classroom in late 1998. It told me real fast the school I went too was a better off one.
McCloud's "Chief"!!! I had this years ago.....thanks for posting this "lost"classic!!!
I'm beginning to wonder if Parts 3 and 4 actually exist, I have never heard of any dead sides being that, and you would think if the entire 2 sided presentation existed it'd be posted somewhere somehow. Another thing.. How are you going to learn how to use the player if you have to play a disc to do it?
probably not. I have the actual disc, and side 2 is a dead side
Finding this after listening to Anders Enger Jensen's "DiscoVision" song for years is like discovering unseen episodes of a show you loved as a kid.
I think that was sampled from this upload also. It wouldn’t even exist if I hadn’t found this disc.
just realised that the laptop I'm using is running an operating system, holds lots of my stuff, plays this video, connects to the internet, can scrub through video fast and can search tons of files very quickly. this laptop is literally at least 8 times thinner than the player
And has no issues with laser rot.
is just alive
jd
Holy-shit, I think I see why they tapped Leonard Nimoy to make the demonstration/sales disc for it! =:O
I think I hit the reject button instead of stop.
Wow - this is pure gold!!
McCLOUD!!!!!
McCLoud!!!! LOL
Now THIS is the future of Home Video Entertainment
