Optimal Media Production

German full service media manufacturer, operating under this name between October 1997 and September 2011.
Then renamed to Optimal Media GmbH.
Formerly operating as optimal media production GmbH when credited as such on the release (e.g. in the CD hub).

Matrix scheme:

XY#####-ZZ (e.g. B847793-01)
(Single letter format identifier, followed by single character year identifier, followed by a 5 digit numeral code, followed by an appended two digit disc numbering).

X is the format identifier:
"A" = CDs
"B" = Vinyl records
"D" = DVDs or Blu-ray Discs

Y is the manufacture year identifier.
For releases manufactured between 1997 and 2009 it is a single number (0 to 9).
For releases manufactured since 2010 it is a single letter (A to Z).
The numbers 7, 8 and 9 are ambiguous and can mean either year:
7 = 1997 or 2007
8 = 1998 or 2008
9 = 1999 or 2009
0 = 2000
1 = 2001
2 = 2002
…
A = 2010
B = 2011

After the 5 digit numeral code, the 2 digit disc numbering (ZZ) can be found, which starts at "01".
On multi disc releases the last digit usually incrementally rises by 1 for each disc. (example: Disc 1 = 01, Disc 2 = 02, etc.)

Examples:
CD: A785283-01 manufactured by optimal media production
DVD: DA98810-01 manufactured by optimal media production
Vinyl: B847793-01 A1

Notes on CDs/DVDs:
• CD and DVD releases additionally carry a "manufactured by optimal media production" string next to the matrix number.
• If the production was done for a manufacturing broker (e.g. Handle With Care), the string often is replaced with the name of the broker.
• The plant's mastering SID codes were: iƒpi (enter as ifpi) / ifpi / IFPI L571, L572, L573, L574

Notes on vinyl records:
• The matrix number can be either machine stamped or hand etched.
• DMM and lacquer cutting are offered in the in-house studio Sector 5 Studios.
• If there are no mastering engineer initials present (see the list below), the mastering / lacquer cutting was done externally.
• Due to the nature of the hand etching, the B (format identifier) might be mistaken for a 3, an 8 or a D. The numeral 1 can be mistaken for a 7.
• Vinyl releases additionally carry the side positions along with an additional digit, next to the matrix number (see the example below).
• There are sometimes additional, faintly inscribed "geometric" marks. These are added during plating, and are therefore mirrored. They consist of a digit and a symmetrical symbol such as +, =, △. Enter these with the run-out string in their non-mirrored form (e.g. "1=") and note this in the Release Notes (e.g. "1= mirrored").

Notes on the manufacturing date:
• The year of manufacture in some cases may not be equal to the release year.
• The actual release date can be the same year of manufacture or the following year (e.g. manufactured in Dec. and released in Jan.)
• The release date cannot be earlier than the year it was manufactured though (there can be certain exceptions though).
• Do not derive a release year from the manufacturing date code alone.

Instructions for entering in the LCCN field:
• For optical discs, please use "Manufactured By" (as on release). For vinyl records, "Pressed By" can be used.
• The job number "XY#####" can be added to the LCCN field. Please do not add the appended disc numbering, this is the internal "article number".
• If a release shows 2 or more of these numbers (e.g. multi-format releases), please enter each number in a separate field.

Attention: Do not confuse the Universal Records catalog number scheme with the vinyl matrix scheme of Optimal Media!
Universal Records catalog numbers can be easily distinguished by the zeros after the B:
• Releases until roughly mid 2007: B000####-XX (B followed by three zeroes, followed by 4 digits)
• Releases since 2007: B00#####-XX (B followed by two zeroes, followed by 5 digits)
(-XX is the release format, e.g. "01" for an LP, "02" for a CD, "11" for a 12" vinyl single).
