DADC Austria

Founded as DADC Austria in 1986, as a 100% daughter of Sony Corporation (according to info on www.sonydadc.com). Production of optical media started July 29th, 1987 when the DADC Austria - Opening Commemorative Disc was provided in their facility in Anif/Niederalm, Salzburg. In 1991 a sister facility was opened in Thalgau, mainly for the production of DVDs. An important reason for opening this advanced technology facility in Salzburg/Austria was the personal relation between Herbert von Karajan and Norio Ohga (大賀 典雄), the president and Chief Operating Officer (COO) of Sony Corp. between 1982 and 1989.
Minidisc fabrication was initiated in the mid 1990s.
~1997 DADC Austria was renamed to Sony DADC Austria AG; this was followed by the 'DADC Austria' disc matrix branding being replaced in approx. 1998-99 by DADC, and then again in 2000 by Sony DADC.

About DADC Austria matrix identifiers

Matrix indicators: 'MANUFACTURED BY DADC AUSTRIA' most probably in use until 1988 (represses occur), 'MASTERED BY DADC AUSTRIA' most probably until 1994, solely 'DADC AUSTRIA' or (DADC Austria logo) most probably until 1998.
1987-1995: 'Label prefix-catalogue number BB CC' (e.g. (logo) CDCBS-450152 43 A1, (logo) BIAS-47-CD 12 A1, (logo) SPOONCD-26 11 A1). CD-singles/Maxis only show 'Catalogue number BB CC (e.g.'
1991-1997: 'nn-xxxxxx-yy BB CC' - (e.g. (logo) 01-468884-10 13 A12) - these nn-xxxxxx-yy numbers appear also on the face of the CD but only when manufactured for the Haarlem production cycle.
1995-1997: Axxxxxxxxxx-yyzz BB CC (e.g (logo) A0100181635-0101 15 A1)*
*pattern remained in use after renaming of the company, around A0000250xxx (~1998) the DADC Austria logo had more or less been replaced.

- For CD releases: 'A' indicates 'Anif', '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). DVDs 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 is stamped into the matrix ring and is usually A1, A01, A00, B1, etc.

From 1994, DADC Austria glass masterings can also be identified by mastering SID code IFPI L55x.

Matrix Numbers

When crediting DADC Austria 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 by, unless there is a specific role given in the matrix (i.e. 'MANUFACTURED BY DADC AUSTRIA').

Please note that all submissions dated prior to July 1987 and all Columbia / Sony Music Entertainment branded releases submitted before 1991 must be considered as erroneous.
