CDs manufactured by DADC (Pitman) (my collection only)

DADC Austria/Sony DADC • DADC (US) • DADC (Pitman) • CBS/Sony/SMEJ (Japan)
DADC's facility in Pitman, NJ was known as Columbia Records Pressing Plant, Pitman before Sony took over in 1988 and converted it to making only CDs for CBS labels. This list is CDs in my collection which I believe were made at that plant.
• matrix thru 1999 includes (in varying order): a code like 1A, 2A, or 1B; a 2-digit code 01 to 09; and a letter+digit code which seems to slowly increment, starting in 1989 with just A, reaching G5 in 1999.
• late 1980s hub stamp: CMU P ## (easily spotted)
• 1990–1997 hub stamp: P ## (easy to miss, it's right by the inner edge of the hub, sometimes cut off)
• IFPI L42x / 72xx SID codes starting circa 1996 (see below)
• Code 39 matrix barcode through 1995; it embodies the cat# without spaces
• Typical DADC matrix barcode starting 1996; not yet decoded
• No four-character "DIDX"-style codes in matrix until 1996.
• Never any DADC crosshair symbols
We are allowed to add Pressed By - DADC, Pitman for these discs, based on the presence of "P" or "CMU P" stamps on the hub, followed by numbers. These codes can be added to BAOI Other fields.
Unfortunately, many CDs have Pressed By - Columbia Records Pressing Plant, Pitman due to vague advice that was given in that company's profile. I've updated the profile and I believe these should all be converted to DADC, Pitman unless there is proof that the DADC name did not apply prior to a certain date.
According to the company profile, Sony eventually replaced the manufacturing equipment and the discs pressed at this plant became indistinguishable (as far as is yet known) from those pressed at other DADC plants. Indeed, I cannot say with certainty where any of these were pressed, if they do not have the "P" hub stamp. Those without the "P" could have been mastered or pressed at DADC's plants in Springfield OR and Carrolton GA, both of which started CD production in 1995. We just don't know yet what discs from those plants look like. One thing I am sure of though: they must have provided some way to tell the discs apart, for anti-piracy and quality control purposes.
