Only use use this profile where a release specifically credits "DADC", or if the matrix contains one of the four-character codes mentioned below and was manufactured before August 2005. However, consider that DADC Codes can be printed on release artwork and on disc faces, but do not always mean that the disc was pressed by DADC; the discs may be glass-mastered and/or pressed by other companies. So if other companies are indicated or can be inferred, or there is any reason for doubt, please omit the credit or ask in the forum.
If "DADC" is mentioned in the following forms, please use those profiles: DADC, Terre Haute, Indiana; Sony DADC; Sony DADC Austria; DADC Austria; or (in Japan) Sony DADC Japan Inc.
The original DADC, a.k.a. Digital Audio Disc Corp., is an optical disc manufacturer whose first plant opened in 1984 in Terre Haute, IN.
Some DADC discs pressed at the Terre Haute plant through 1992 have the DADC "D" logo molded onto the clear plastic hub/clamping ring. This logo by itself on the hub of a US pressing is sufficient for the LCCN entry Pressed By - DADC. Likewise, hub text such as "Made in USA - Digital Audio Disc Corp. [D logo]®" can be interpreted as Pressed By - DADC, Terre Haute, Indiana.
Additional DADC plants operated in Pitman, NJ (c. 1989–2011); Springfield, OR (1995–2003); and Carrollton, GA (1995–2001; then continued as a distribution centre until 2013). As yet, it is unknown how to reliably distinguish discs from most of these plants.
Discs from the Pitman plant through about 1995 do not have the four-character matrix codes, but can be identified by "P" or "CMU P"-prefixed numbers stamped on the clear plastic hub/clamping ring (sometimes very tiny, right by the innermost edge); these codes can go in BAOI "Other" fields and the releases can get the LCCN entry Pressed By - DADC, Pitman.
DADC Austria has been operating in Anif, Austria since c. July 1987, and was officially renamed Sony DADC Austria AG sometime in the mid-1990s. Despite this, the DADC Austria logo in disc matrices from this plant was not replaced by Sony DADC until ~2000 (and briefly by the generic DADC logo between ~1999–~2000). Please credit DADC Austria, DADC, or Sony DADC depending on the logo present in the CD matrix.

Discs glass-mastered by DADC can be identified by the following codes found in the matrix (not a complete list):
· CDRM (CD-ROM)
· CSIG (3" CD Single)
· DIDC (Sony Classical)
· DIDP (Sony Popular)
· DIDX (Non-Sony)
· DIDY (Columbia House)
· DIDZ (WEA Japan, 1983-1985)
· DIPX (Non-Sony Promo)
· DISP (Sony Promo)
· DRSS (DVD-ROM)
· DVDL (Dual-layer DVD)
· DVSS (Single-layer DVD)
· LDVS (Laserdisc)
· PSRM (PlayStation)
· SPLD / SUHD (Hybrid SACD)
· STLD / SUHD (Hybrid SACD)
· SUDL (Dual-layer SACD)
· SUSS (Single-layer SACD)
In 1988, codes were extended to have six digits: therefore any 6-digit DIDX/DIDP codes (i.e. DIDX 00nnnn) on CD face/artwork or in the matrix can't be earlier than 1988. Sometimes older CDs originally released without leading zeros (e.g. DIDX-nnnn) were repressed with the new format (DIDX-00nnnn).
When the DADC number (see prefix list above) is present in the CD matrix (e.g. DIDX-12345), it may be entered in LCCN as the catalogue# for DADC, with the following exceptions:
• a release manufactured after August 2005 (more easily identified as any release with release date 2006 or later), which should instead be credited to Sony DADC
• a release with matrix number DIDX-12xxxxxx or later, which is approximately the place in the DIDX- numbering scheme when DADC was rebranded to Sony DADC in 2005-06
• if the code is printed on the artwork but not in the matrix, it should not be entered in LCCN, but in BaOI as Other (DADC Code)
Please credit DADC with the role Glass Mastered At when identifying from these matrix numbers - Pressed By should only be used when the DADC 'D' logo or 'Digital Audio Disc Corp.' is moulded into the inner matrix hub.
For example, the following releases have the DADC code derived from the CD matrix and entered in LCCN:
Theatre Of Tragedy - Aégis
Nightwish - Angels Fall First
