CD matrix manufacturer (Wiki based Version 2). Discussion Thread

Welcome to the Master List of CD matrix manufacturer information (version 2)

The list is now discontinued at the wiki CD Matrix manufacturing list and this thread will only serve to discuss the content on the wiki and to propose new additions, edits

Last version can be found at archive org https://web.archive.org/web/20220525230141/https://reference.discogs.cinepelis.org/wiki/cd-manufacturing-companies-from-matrix

A big thank you to everyone who has ever contributed to the last thread. Especially thanks to Old and abandoned thread

Thanks everyone who still uses this thread to discuss CD manufacturers and the kind souls that update the wiki with new or updated information.

Hi,
Thanks for this work.
Is there not a typo on EMI Uden line?
Would like to update but don't know how do proceed for linked name.
it doesn't work as your example.

Thanks for this Wiki page velove

thanks for spotting. updated and added a link to the profile
each line in the table has the following structure

| Matrix text | [name of the url](url) | optional comment |

for example
| EMI Uden | [EMI Uden](https://discogs.cinepelis.org/label/266256) | optional comment |

Ok 😬 no space between [label] and [url].
Many Thanks.

Updated some links and some details/typo.
Will fix more :)

Proposal to add
www-odm-ltd.co.uk
as credited on Jake Cogan - Parcel Of Rogues

web address goes nowhere, so probably defunct, but connected to ODM

Proposal to add
www-odm-ltd.co.uk

isn't that an incorrect profile? www.odm-ltd.co.uk would be proper URL and as on release, why use www- instead of www.?
http://web.archive.org/web/20080112162934/http://www.odm-ltd.co.uk/

I found several releases from Thailand with a "DMD" logo in runouts but still i have no idea which company it could be.

Maybe anyone else have?

yes seems to be the case. it should be www.

andygrayrecords
but connected to ODM

all the ODM profiles are missing. There is also ODM America.

Maybe it would be a good idea to start linking to an example sub for each entry in the list. Like it's done in the vinyl runout thread.

Regarding NIMBUS.
Nimbus Artist
Label should be linked?

SM but the exact relationship is not known, either the same company or new iteration of that company.

I have linked label already in list, and added a "See also Nimbus" in the comment field.

start linking to an example sub

With correct datas....+1

Have added a link to the first entry in list.
Placed it with the label profile section, IMO it looks better than adding a new field.
Is it ok like this, and can be used?

Other (Outer Ring): 'MPO' [Swirl Symbol]

Matrix data always needs to be in the Matrix/Runout dropdown and not with the other. so the linked example should be updated.

Ooh, I missed that.

DW (2) is an Australian pressing facility recognisable by DW in the matrix and the mastering SID code IPFI LR11.

is DW alone not enough? Is it only the combination that should be credited to DW (2)?

maldoror
A CD with this pressing information can be dated to 2014 or later

Why 2014 or later? If the company didn't exist before or used a different name, then the profile should be updated with the info. Makes it easier to understand the why.

Can you link to a sub with it? Ideally with an image of the matrix area.

velove

DW alone would be enough I suppose, I don't think I have seen it without the SID code though.

An example of a release with discs from Russell Morris - Red Dirt - Red Heart
An example of a release with discs from The Hits / The B-Sides (no images)

This CD has a Untitled

The relationship to SM is ambiguous, they have almost identical webpages (which are down at the moment) and the physical address is next door to each other. They may be the same company or DW may be a new iteration of SM.

Hi, don't know if we need to start a new discussion or ok to ask here. About John Wetton - Battle Lines. Comparing it to other versions under the profile, there are those with KEY + # like on the edited release, but have the www. names also in the matrix. The profile states: "Please only use this profile for releases which specifically mention "Key Production". What about releases that just mention KEY? Anyone know perhaps?

jansenENjanssen
What about releases that just mention KEY? Anyone know perhaps?

The standard is to use exactly what is in the matrix, which is why we have a bunch of URLs representing pressing companies and brokers now. See DW (2) credit.

CD manufacturing is complicated. Then company and the characteristics in the matrix can be one of three steps in the manufacturing process.
1) glass master company.
2) actual pressing plant
3) manufacturer of CD pressing machine
https://en.wikipedia.org/wiki/Compact_Disc_manufacturing
It would be great if we could somehow add this information.
For example a CD glass mastered at Toolex Alpha Machine.

CD manufacturing is complicated

Complicated it is.
I use a generic credit as Manufactured By or Made By, when it gets to complicated :)

On the wiki there is DiskBank, it states that they are a broker but their website states that they have "replication and printing facilities in Perth and Sydney"

maldoror
On the wiki there is www.diskbank.com.au but not DiskBank, it states that they are a broker but their website states that they have "replication and printing facilities in Perth and Sydney"

Good to see that someone is awake :)

The company roles that should be used for the companies on the list, how do we know which is correct to use? Some have roles clearly explained based on information found on the releases, others seem to be less clear, as on CBS/Sony Records Inc., "Japanese record and manufacturing company", "80s and '90s have a mould manufacturing print" but later on the advice is "please used at 'Pressed by' !" The information presented suggests Manufactured By role, why Pressed By advice?

Same situation for Sony Music Entertainment (Japan) Inc., added by the same member.

jansenENjanssen
The company roles that should be used for the companies on the list, how do we know which is correct to use?

It would be good to have a simple recipe but that will not work in many cases. It is thus at the s discretion to choose one of the possible roles.

If in doubt, use a more general role. When it's clear it would help to have some guidance, roles specified on the wiki as well.

Wanted to add A1 Duplication, but there are 2 more profiles created for the same company.
We then have:
www.a1duplication.co.uk - Seems to be made up, doesn't appears with www in matrix for anyone I have search for.

A1D London Ltd, seems to be the correct wording, according to site.
www.a1duplication.co.uk - IMO, to be invalidated.

Any opinions if we should use A1 Duplication or A1D London Ltd?

Will update profiles, links and releases when there's agrement for what company to use.
Thanks.

Thanks Eviltoastman and now yours to keep such interesting data collections alive!

Can you start a new forum thread to find out more infor about DW, Discworld and the relation to SM?
archive.org shows Discworld website with news saying introduction of Blueray in 2011 and Eco disc in 2010. --> Why is it written on proile that it can be used from 2014 onwards. This should be discussed in own thread.

jansenENjanssen
Hi, don't know if we need to start a new discussion or ok to ask here. About Key Production, we edited a release with just the word KEY in the matrix, John Wetton - Battle Lines. Comparing it to other versions under the profile, there are those with KEY + # like on the edited release, but have the www. names also in the matrix.

The release that you link to is from Australia while Key Productions is from the UK so I'd say that in this example there is no connection.
What other releases have you found that have just KEY and a url?

jansenENjanssen
The profile states: "Please only use this profile for releases which specifically mention "Key Production". What about releases that just mention KEY

if a release has KEY and www.keyproductions.co.uk for example then Key Productions can/should be credited imho. the wording of the profile has the intent that you must not credit the url profile if only the name is there and vice versa.

maldoror
The standard is to use exactly what is in the matrix, which is why we have a bunch of URLs representing pressing companies and brokers now. See DW (2), we know the company is called Discworld but it is only on some discs, so the discs that have DW in the matrix get a DW (2) credit.

Abbreviations of company names are special cases. DW and Discworld should both be credited to the same profile.

earshot
1) glass master company.
2) actual pressing plant
3) manufacturer of CD pressing machine
https://en.wikipedia.org/wiki/Compact_Disc_manufacturing
It would be great if we could somehow add this information.
For example a CD glass mastered at EMI Swindon pressed by EMI Uden on a Toolex Alpha Machine.

If you have example releases where you can explain which companies are used for what and why then they can be linked. Either directly in the table or in a special section that explains how to properly read the more complicated cases..
Feel free to post examples here and I can see where/how to put them on the wiki

I'd treat A1 Duplication and A1D London Ltd as different entities. legal ending and without --> separate. They can both be added to the wiki.

UK label, is it unlikely the disc was also made in UK? IFPI LP76 on the search here shows it to be on UK releases. Will leave that for the moment, maybe we can find out some more.

Is it possible to add to the wiki list which profiles you can add a number to the company credit where it has been confirmed these are correct to add? We regularly come across submissions with a number added to a company where we cannot find any references for these on a profile (just edited a release to add Mr. J. Medeiros - Milk And Eggs, etc.)

jansenENjanssen

It's is possible that it was glass mastered in the UK and pressed in Australia as many CDs were in that time period.

I've now added entries for Key Production
lots of entries on Key Production are possibly wrong or an 2nd credit could be added.

I was one of the voices in the www thread arguing for use of company name when the link is certain, it is unfortunate because we have been told many times it is a database and guidelines are driven by the community but in this case the majority community decision was ignored and overruled.

I'll se what I can do as it wasn't my CD, it belongs to someone else. From memory it looks like the logo on the recently non existent website: https://web.archive.org/web/20160313203322/http://discworld.com.au/

Hey guys, I noticed that Disc Partner). The (catalogue) numbers match the timeline. I have ca. 7 - 8 CDs from them in my possession. Should it be mentioned in the profile ? (so that the people can enter the continuous number) You can always see the number in the matrix: Disc or disc or DISC and then the number. And if it would be ok, then with DISC/Disc/disc or without ? I could make an update and an edit. Disc Partner is also not in the wiki (CD Manufacturing Companies from matrix) list. Opinions & suggestions ?

can you please create a new thread.
see
https://discogs.cinepelis.org/forum/thread/369225#3425666
The exact method of extracting this number is the problematic part, as discussed above. Each plant has to be studied and a method found for that particular plant, if there is one to be found at all. In all other cases, the field should be left blank.

On Docdata Ablex but I'm not sure if this is valid profile. Any suggestions? Is one company responsible for the glass master and the other the pressing or did they merge at some point?

When searching Discogs there are a handful of releases with DOCdata ablex U.K in the matrix.

Cinram Canada. Added to db a few months ago. Is this a valid entry?

Please Can you add PMDC, in your list please

Cinram Canada. Added to db a few months ago. Is this a valid entry?

don't think it's valid. Cinram is the canadian branch. It was the OS first ever submission so likely to not be 100% perfect.
marked the profile as invalid

oceanographer
An entry exists for Docdata Ablex but I'm not sure if this is valid profile.

Looking at Josie Walker With The Omagh Community Youth Choir - Let Us Love In Peace the notes say
"This compact disc kindly manufactured by Docdata Ablex"
if written like that it it looks like it's valid.
googling I've also found an entry confirming that the company was referred to like that
https://books.google.ch/books?id=i-EhaK9f-PYC&pg=PT405&lpg=PT405&dq=%22docdata+ablex%22&source=bl&ots=APN28oqSCD&sig=3WwOUwtYpMyTI3QZCFXIKMawVIk&hl=en&sa=X&ved=0ahUKEwjpmNiniODOAhXIvBQKHfWwAycQ6AEILjAD#v=onepage&q=%22docdata%20ablex%22&f=false

More research would help. Company registrar etc.
I am now wondering if splitting into Docdata UK and Ablex when coming across "DOCData Ablex U.K." is correct.

Hi DOCdata press in my collection.
I have no scanner to make propely scan of matrix area but on label page, the right logo is showed..

I've just added the Matrix info to Koji Asano, Koji Asano Ensemble - Flow-Augment, with the following submission notes:

"I did the best I could with 'ATD Alta. Tecnologia En Duplicación S.A.', but it is really hard to read, and I couldn't find the company.
I'm pretty sure it's a Spanish CD maker, but I couldn't confirm. If you know it, please adjust. Thank you. "

Anyone have any knowledge about this company?

When found in a matrix, does REV/CA indicate a manufacturing or pressing credit? Version 1 of the CD matrix thread http://discogs.cinepelis.org/forum/thread/52151a969469733cfcfbcbde points to the Revolver USA page. Most of these entries credit Revolver USA as a distributor. Did they also manufacture media and if so should they be credited on releases with a "Made By", "Pressed By" or the like when REV/CA is found int he matrix?

The company roles that should be used for the companies on the list, how do we know which is correct to use? Some have roles clearly explained based on information found on the releases, others seem to be less clear, as on CBS/Sony Records Inc., "Japanese record and manufacturing company", "80s and '90s have a mould manufacturing print" but later on the advice is "please used at 'Pressed by' !" The information presented suggests Manufactured By role, why Pressed By advice?

Ah yes of course; thank you! I knew it would be a big manufacturer as I'm sure I've seen it on lots of CDs!

I came across SIDI today which isn't on the wiki page yet.

Label profile states "Recognised by SIDI CO. JEDDAH KSA S [year] KSA ZZ BA STM [cat. nr.] in the matrix area."

However the second 'KSA' is 'UAE' and the 'ZZ' is 'EM' on my release.

The release in question is on EMI Music Arabia which could explain the EM as a label identifier maybe and UAE could be the country it's destined for perhaps?

UAE is short for United Arab Emirates, so is plausible, maybe sayed_effendi who edited the profile knows more?

KSA is Kingdom of Saudi Arabia
UAE is United Arab Emirates

Will have a look at it. I wrote the profile based on the matrixes available at that time.

Is this the release concerned Erasure?

There we have SIDI CO. JEDDAH KSA S 95 UAE EM DE STM 894 0101
Still the year (95) and the sequential number (894) is valid, but the letters differ.

There are others that have UAE EM:
SIDI CO. KSA 96 UAE EM BA STM 1258 0101
SIDI CO. KSA S 96 UAE EM BA STM 1448 01

And there are other variations to like:
SIDI CO. KSA S98KSAMGBASTM275801 01

Maybe the SIDI CO identifies it. Followed by year. Followed by some other codes. Followed by sequential number.

Those that have UAE EM in the matrix string seem to be manufactured by SIDI for EMI Music Arabia which is based in the UAE.

The info between the year and the STM seems therefore at first glance to be additional info for other companies for which the release was manufactured.

Here: SIDI CO. KSA S 98KSAFRBASTMS55201 (KSA = Kingdom of Saudi Arabia) FRBA seems to point towards Farasan somehow.

So EM = EMI / FR is Farasan. Have no idea what BA/DE and STM stands for

No, I hadn't submitted it yet when I posted that; it's now here: أم كلثوم* = Omme Kolsoum* - La Diva III

Thanks!

Made in the USA BY L&M?

will look into the new comments over the weekend.

There seems to be a lot of releases with MG/CA credited in matrix area.

Should we now use also this plants for CD's? RSA = WMME Alsdorf?

For Alton2 though any source were lacking, can anyone confirm those are indeed sequential company numbers that should be added to the company?

Anyone maybe know if the LDA in matrix on Phil Collins - Face Value refers to any company entity or is it just letters in the matrix?

We know that musik-sammler is not exactly considered as anything official, was it correct to add info based on there?

Lor Disc needs to be merged with Lordisc

not really. it should be a starting point for further research only. removed the SID code reference from the profile and added links to other sources for the other info.

For Sonopress, Hong Kong, erdeimano has added a bit about pressing numbers without any reference/source/backing (as seems the usual case for this member) and voted correct by Alton2 though any source were lacking, can anyone confirm those are indeed sequential company numbers that should be added to the company?

have reverted the edit. Needs forum discussion, research and consensus before. Numbers added to Sonopress, Hong Kong are not valid until then and can/should be removed.
