- In 1995, Disc Manufacturing, Inc. moved to their new facility in Anaheim and they produced this promotional video showing the manufacturing process for a Compact Disc. I recently found one of the three VHS copies in existence and here it is. This proceeds DVD by a few years, however many of the manufacturing steps are the same. Enjoy!

I worked for this company from 1993 until the bitter end in 2001 when it was shut down and moved to Huntsville Alabama. I thank this company for giving a young guy an opportunity to become a journeyman maintenance mechanic. I had a lot of good memories working there.
Jeffrey Montoya what did you do specifically with DMI? I'm curious if I remember you.
breckrowell I worked for the maintenance department. I was a Facilities Maintenance Mechanic and worked under Allen Turner. George Lewis and Ken Ames were the ones that trained me.
do you know what type of paint is used?
Cool history. I’m living in Huntsville now.
Wow... this brings back some memories... Worked there from 1993 to 1997.. when DMI was across the street. Ofcourse I was young, in packaging then to materials. And when moved next to frys.. Stockroom and warehouse.. Those were the days.. I even recall folks on the video..😂😂
It's incredible how long the technology has lasted, we can still find plain regular CDs 700MB brand new and sealed in stores all over the planet.
I worked for DMI from 1986 to 1997 as a Mastering tech and finally a Product Engineer.
From SoCal, and I remember them and this era.. Sad to see the Huntsville site permanently closed.. Thanks for posting.♥
The year is 2020 and I still like to use CDs. Nostalgic.
Love the background music at the beginning, by the way =)
cd's blow mp3 out the water. especially if it's properly mastered.
Was in this industry from 1992 to 2009 till my plant shut down. CDs died Was a great job. Worked on the molding machines. Metalizers. Spincoaters. Inspection. And print machines. Even the dryers and feed systems. Sure miss it
I worked at Disc Manufacturing Huntsville in about 1995 or 96 doing manual inspection just after Screen printing and then moved into the cleanroom doing automated inspection just after Met/PC. Got laid off just after the Christmas rush finished. Went back to work at Cinram in 97 or 98 for about a year as a screen print operator. B team was always a fun shift and Don Saddler was a good boss.
A good find. Thanks for uploading.
I worked in the Mastering Department
Cinram / Disc Manufacuring Inc - Anaheim, CA October 1992 to December 1997
The record companies need to make use of all that dynamic range. There was an article on soundonsound about the loudness war possible ending, I can only hope.
so sophisticated and crazy to think that is obsolete now.
I like how they always put the CD in the players upside down to not show the label.
_"I like how they always put the CD in the players upside down to not show the label."_
Or the CDs being tested may have been random pulls prior to the labeling process from the production line for a QA check.
Hey Breck. Do you remember when we were working on Jurassic Park DTS disc? I was working out the problems we had with mastering through the night without any engineer, and I finally was able to get a "working Master", but it was to late to ship to the premier in LA. so I think you got to bring it personally to the premier with Spielberg and cast and crew...
Thanks for this, it was interesting to watch. Did you used to work for DMI by any chance? I have been trying to find out some specific info about them relating to the mid 90's
I know, i have a degree in audio engineering circa 1987, though, I wanted to know HOW and what was put on the glass disc, and your program explained it---such like a Nauman [sp?] cutter head cuts the grooves on the old LP's. (and still does today)
Thanks for the great vocal-to-background music. One I tried to watch make theirs like a rock CD mixed down by a Rock recording Engineer.
why are they putting CDs in cases and then inserting it into computers? Is there any model number for those type of drives, they seem interesting and I would like to look them up. Thanks
That's how they used to do that in the beginning, the case was called a caddie. Not all drives did that, but some did. The first CD-Rom drive I had was a Toshiba 3401 and it used a caddie to protect the CD.
breckrowell thanks for the info, interesting stuff and i love learning about older tech
A lot of radio stations used professional CD players that also used caddies to load the CD's. They were thinner than the one shown. The CD's would stay in the caddie on a wall, all numbered for easy access by the DJ. Just pull it off the shelf and shove it into the CD player it would load as fast as you could pop it in and wait for you to select the track you wanted. Waiting to be played, usually triggered from the audio boards input for the CD player by the DJ. As new CD's came in from the library subscription company the station subscribed to, they would remove them and put in new CD's over time. Cycling out the older CD's if it was not a permanent library like oldies or classic rock etc. I think they sent them bi-weekly or monthly. They were manufactured CD's not burned ones, being that this service started way back in the 80's, even to the late 90's they were manufactured red book CDs with silk screen print. It was a nice service. Later on stations would just buy entire catalogs on pre-loaded hard drive's to play from the automation system.
@1969atam Stock footage, I think. I don't recognize the person.
Probably due to advances in replicating technology older CD (DVD) will not play or completely play on newer players such, in my case, on my computer! CD may last a hundred years [as said], but that's no guarantee they will play that long. Also, CD's recorded on multi-recorders such as those used in Churches, etc of the day's service--as I did for months--are NOT the same as those replicated--pressed fashioned as the old 78's and vinyls were.
interesting. were tests ever done on longevity? do you have discs from early 80s that still work well? really the lacquer seems the most important part as it protects the data?
The coating process is very important and in fact they did environmental chamber tests early on that predicted that discs that were kept in a cool dry place should survive for 100 years. I have many discs that were made in the early days that still play perfectly. I haven't put any of these discs on an error counter to look at block error rate, but the all sound fine to me.
+breckrowell cool. i think my oldest disc is about 25 years old. it seems fine to. they say vinyl could last 1000 years, but if you were to play it a lot it would wear out quicker than a CD. do you think CD has a good future? i wonder how the ultra HD bluray will take off.
+Kailash Personally, it looks to me that optical discs are going the way of the wagon wheel because everyone is moving onto digital downloads or streaming audio/video. I still insist on having a physical copy of my movies/music because I don't want to lose my collection due to a hard drive crash and want to still have access to it even if I don't have internet access. That's just me and a lot of people don't feel the same way. I'm not sure how newer formats will do due to the move away from physical media, but I guess time will tell.
I have CD's from the 80's ripped to FLAC no problem. Longevity for moulded CD is OK.
8:15 - Maybe if some vinyl pressing plants took this step, then there wouldnt be so many garbage pressings out there now.
As I have been informed, the Reflective Aluminiun Layer may degrade with Time, even on Recordables but as well on Standard Mold-pressed Media. Especially if it has been applied very thin. Other Recordable Media in my own Home already had developed Defects with time, such as the Reflective Layer getting loose and breaking (flaking) away.
I can agree when it comes to recordable CDs. As of moulded ones however if you take care of them, they are far more resilient. Just in the touch you know there is a difference between recordable and moulded.
Recordable will last from a year to like a decade while moulded will go beyond that. What I can tell you is I can still rip CD's from the 80's/90's. It is like 30 years now. And now I think about it I have CDs from albums that were released in late 70's but it needs some more info. I did not found a release date printed anywhere. Still CDs can last decades no problem. I use them only for ripping if needed which mean almost no more. I listen to the FLAC files instead.
Whether the aluminum substrate degrades depends on whether the disc was made properly and how well it's been taken care of throughout its life.
The first thing to fail would have to be the lacquer seal as that's what keeps the aluminum protected from exposure. But, this layer of lacquer is very thin, so it can be damaged if the disc is carelessly stored and/or handled.
For instance, if you put CDs into a flexible CD wallet, the abrasion of the lacquer from the wallet can cause damage. Another is if you have a habit of laying a CD label-side down against a hard surface; any granular particulates that happen to be sandwiched between the surface and the disc can poke through the lacquer.
Breaking the lacquer seal can expose the aluminum to oxygen, which can cause it to break down via oxidation. There's also the risk of the aluminum being scraped off with the lacquer, which isn't good. And unlike scratches on the iridescent side that can possibly be polished away, scratches on the lacquer side are permanent.
As for certain recordable CDs, it's not just the reflective substrate you have to worry about. You must also worry about the stability of the recording dye, and usually that's what breaks down, especially if the disc is subject to exposure to excessive light and/or heat. And some recordable CDs are better at lasting a long time compared to others. Some of the best CD-R media were from companies like Taiyo Yuden, who used to make discs in Japan. Now, your best bet are media products from Verbatim (Mitsubishi), specifically their DataLifePlus series using AZO dye.
See the hot blonde at 3.00? I did :-)
@3:00
They were aware of covid 19 in 1995
so they are taking credit for producing the first cd in 1983... funny though since the firt cd was made in germany in 1982 by polygram
typical american trying to take credit for things they have not done
Typical foreigner arrogance. See? It sucks to generalize an entire nation.
D.M.I. never claimed to make the first disc in the world, but they did make the first one in the US.
boundish1 but seems he said "the first CD made in USA"
Master and Servant
He said: "When the first music compact disc was made in America in 1983..."
Typical foreigner talking dumb shit.
