More tips to uncover fake CD-i demonstration discs; don't spend lots of money on cheap reproduced CDR discs!

We discussed before some valuable tips how to distinguish real CD-i demonstration discs from fake copies. There are currently a lot of fake CD-i discs being sold which are all from the same white label as Philips Interactive Media of America used to press in the past, purely for demonstration purposes. But this black/white designs are easy to copy and to reproduce. They all state that these discs were produced by PMDC in USA. PMDC stands for PolyGram Manufacturing & Distribution Centre. It was in Europe active from 19 April 1996 until 28 March 1999. It was a UK based manufacturing and distribution company, operating a CD pressing plant based in Blackburn. PMDC, UK CDs are identifiable by MADE IN UK BY PMDC. There also was, however, a PMDC in the USA according to the same site.

Next to the previous tips, we can add some more valuable lessons:

  1. The white lines in the Philips Interactive Media of America logo are not correct, they should be all white with a clear separation. These look blurry/blocky due to low-res image source.  The printing on that disc still looks way off compared to real demonstration discs (acquired via Philips employees 10+ years ago). This is mainly because these discs are printed using inkjet printing and the ink can leak on small lines, as present in the PIMA logo.
  2. It strikes me that Pac-Panic was a 1996 title, never released in USA. Moreover I have never seen anything of Pac-Panic before that originates from PIMA. Philips Interactive Media of America stopped business in 1995. It's purely this that I already doubt the genuinity of this disc.
  3. One typical font is used for these fake discs, which already have a high risk of being fake. Look closely to the font of 'The Lost Ride' and 'Pac-Panic' below.
  4. The inner rings look different from each other, revealing different types of CDR have been used. 
  5. The outside of the top layer is silver on original discs, there is a blanc ring around it.
  6. Always check if the back is silver and coded in the central ring on the back.


It's interesting that they reveal itself to be fake when you look closely to the type of disc, this one above is home-made printed. The leaking of the inkjet lines seems also to be clearly visible in the PIMA logo, that's true. Nice, more proof of how to spot fake discs!


To me the white lines do not look good when compared to a real disc (of which my photo also does not do justice). Finally, compare it to a verified original one:



The best tip remains: ALWAYS ask for a picture of the backside, especially showing the codes of the inner ring. Retrostuff:"US CD-i mastering codes usually end with [space]0[1-3]!, as you can see below from a genuine demonstration disc. Next to it you see a mastering tool stamp (D), usually a single character. These things are impossible to recreate at home / with a CD burner."
