The Austrian pressing plants DADC Austria was re-branded Sony DADC in approximately 2000, at which time Sony DADC first appeared in the matrix of CDs manufactured there. The same happened in the US in August 2005 when Digital Audio Disc Corporation changed its name to Sony DADC US Inc.
Blu-Ray production began in May 2006 in Terre Haute, IN, USA, and in July 2006 in Salzburg, Austria.
In 2006, Sony DADC purchased a disc manufacturing plant in Southwater, UK and a distribution centre in Enfield, formerly operating as Deluxe Global Media Services (Deluxe (7)), from parent company the Rank Group. Production was ceased in the Southwater plant sometime in 2018
Sony DADC expanded into the Czech Republic in 2010, and since then has shifted progressively more of its assembly and distribution business there from Austria. As of 2020, Sony DADC's manufacturing operations in Austria have been consolidated into one manufacturing plant in Thalgau; a second Austrian plant in Anif is no longer operational.
In 2011, Sony DADC's manufacturing facility in Pitman, NJ was closed, leaving only the facility in Terre Haute, IN operational in the US. It was announced in January 2018 that the Terre Haute facility was moving away from CD, DVD and Blu-Ray production due to the changing market, but would continue to manufacture PlayStation discs and new formats such as Ultra HD discs. This ended Sony DADC's CD manufacturing activity in North America.
Please only credit Sony DADC if it is specifically mentioned on the release or properly identified as outlined below. If in doubt, please ask in the help forums.
European matrix identifiers and LCCN roles
Sony DADC releases manufactured in Austria usually have matrices in the following pattern:
Sony DADC Axxxxxxxxxx-yyzz BB CC or
Sony Music Sxxxxxxxxxx-yyzz BB CC
· For CD releases, yy indicates the disc number (always 01 for single-disc releases; 02 and onwards are used for multi-disc releases), while zz indicates the number of discs in the release (again, always 01 for single-disc releases). SACDs/DVDs/Blu-Rays use different numbering for the yyzz part/
· BB is a two digit number, usually between 11-25. The second digit is the same as the last digit of the mastering SID code (IFPI L55x).
· CC may be stamped or printed in the mirror band, and is usually A1, A01, A00, B1, etc.
When crediting Sony DADC from the matrix mirror band, by the presence of its name/logo, with or without the Axxxxxxxxxx-xxxx matrix number and mastering SID code IFPI L55x, the most accurate role to use is Glass Mastered At.
When entering Sony DADC matrix numbers into LCCN, ONLY the "Axxxxxxxxxx-yyzz" / part of the string should be entered. An example of how to correctly credit Sony DADC can be found on Murkrat - MurkRat. The Sony DADC name may omitted (and sometimes replaced by the logo of Universal on discs manufactured for Universal record labels), but can still be identified by the Axxxxxxxxxx-yyzz matrix number and mastering SID code IFPI L55x, for example Rory Gallagher - Blues.
For discs that have the "Sony Music Sxxxxxxxxxx-yyzz" style matrix, please enter in LCCN:
Made By – Sony Music – Sxxxxxxxxxx-yyzz
Glass Mastered At – Sony DADC [this line should ONLY be entered if the release is definitely manufactured in or after 2000, as DADC Austria and DADC were still being used in the matrix before then]
More recently, the Axxxxxxxxxx-yyzz matrix number may be omitted, and replaced by a portion of the release catalogue#. This is most commonly seen on releases manufactured by Sony DADC for Universal. In these cases Sony DADC should be credited with Glass Mastered At as normal, but no catalogue# should be entered in its LCCN entry. Examples include Queen - News Of The World and Rammstein - Reise, Reise.
Finally, both the Axxxxxxxxxx-yyzz matrix number and the Sony DADC name may be completely omitted from the matrix. Such matrices generally have the following pattern:
[release catalogue#] BB CC,
as well as mastering SID code IFPI L55x. If the release was definitely released after 2000 (when Sony DADC name began appearing in the CD matrix), Sony DADC can be credited with Glass Mastered At, with no catalogue# entered in its LCCN entry. Examples include Colosseum - Valentyne Suite and Helloween - The Time Of The Oath. However, if it is uncertain whether a given disc was manufactured before or after 2000, please do not attempt to credit Sony DADC.
US matrix identifiers and LCCN roles
The following prefixes may appear on releases manufactured by Sony DADC in the USA after August 2005.
BVDL- (dual layer Blu-Ray), BVSS- (single layer Blu-Ray)
DVDL- (dual layer DVD), DVSS- (single layer DVD)
SUHD-, STDL- (SACDs)
Before August 2005 these prefixes appeared on the artwork or in the matrix of releases manufactured by DADC.
When this number is present in the CD matrix, it may be entered in LCCN as the catalogue# for Sony DADC, with the role Glass Mastered At. (Note that if the code is present on the artwork but not the matrix, then Sony DADC should not be credited). An example is Lady Gaga - The Fame Monster
As a general rule, CDs with matrix number DIDX-13xxxx and later will be post-August 2005 releases manufactured after the US rebranding to Sony DADC. Sony DADC manufactured many reissues of older CDs, especially after the closure of EDC, USA, and many older releases have been repressed since 2005. If the matrix number is later than DIDX-12xxxx, you can identify such post-2005 represses.
