What goes in the Matrix Number and Other fields ?

Can someone tell me what exactly the matrix number is and where i'd find it on a cd, if at all.

Also i have noticed some data on the inner circle of cds - would this be handy to have entered ? (is one of those numbers a matrix number ?)

I'd also like to know if the 'Other' field has any relevance to cds as it seems to be more about vinyl.

i'd like to know that too. but esspecially for vinyl. matrix number= run out grooves?
what about taking Label code and "GEMA" (for example) in the "other" field?
sorry for my bad english...

i think i'll just forget all about matrix's and other data for now.

For vinyl, Matrix Number is a number usually etched into the runout groove of a vinyl record that is used during the manufacturing process to identify the acetates and stampers used in making the record. Commonly, the matrix number is the catalog number modified with an 'A' and 'B' or '1' and '2' afterwards. However, the matrix number can also have no relation to the catalog number. Also, the run out groove information can contain other numbers that are not the matrix number.

Please ask in the Adding & Updating forum if you need help in interpreting a specific example.

hello XXXLLL,
hello all,

that barcode/Matrix/Other field imo gets started to fill in specific informations, coming with this release and alone for this release to ID that Item (am i right?)

LC and GEMA entries are not specific for that field, because many releases have that LC# and GEMA, BIEM, STEMRA or other notes.

i think it is more a fingerprint that identify a release clearly.

if i'm wrong, please tell me, thanks :)

Since many of the currently pressed European vinyls are possibly manufactured by GZ Vinyl, I can explain the basics of their matrix scheme. Their matrix numbers have no relation to the catalog numbers, however a part of the matrix number may have a relation to their internal client IDs, or to the vinyl format:

Until recently, a matrix number pair would usually appear as "XY 12345/A" and "XY 12346/A"
The latest releases use a scheme like this: "12345X1/A" and "12345X2/A"

- The last number before the slash denotes the side, the lower one usually indicates the a-side.

- The character after the slash is obviously the stamper code. Most small editions will have a stamper "A", represses or different pressings (e.g. colored vinyl) may have a stamper "B", "C", etc.

(Basically, this scheme even applies to most vinyls pressed by GZ since the 1950s, i.e. 99.9% of the Supraphon/Panton/Opus vinyl. However, many popular pre-1990 releases were pressed on several machines simultaneously, so the stamper or machine codes after the slash could have been different even within one edition, thus not necessarily denoting a unique release then. Additionally, the "clean" matrix numbers were also printed on the respective center labels.)

I think this section needs to be updated. CDr's CAN have SID codes
