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-catalog 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 'Catalog 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.
LCCN Roles and 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 At, unless there is a specific role given in the matrix (i.e. 'MANUFACTURED BY DADC AUSTRIA').
When entering DADC Austria matrix numbers into LCCN, ONLY the "Axxxxxxxxxx-yyzz" part of the string should be entered.
An example of how to correctly credit DADC Austria in the matrix is Burzum - Filosofem.
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.
