I’ve just found a comments in a old thread http://club.cdfreaks.com/showthread.php?t=116008&highlight=Taiwanese+Verbatim
i’m gonna reporting to know if things have changed since then:
[I]Verbatim Data Life Plus discs made in Taiwan are made by CMC Magnetics under licence from Mitsubishi. They are manufactured in accordance with Mitsubishi’s quality controls and standards and have exactly the same media code as those manufactured in Singapore.
MCC02RG20 is the media code for Verbatim dlp 8x -Rs whether manufactured in Singapore or Taiwan.
However, there is nothing to worry about wherever they were made. I have both Singapore and Taiwanese manufactured Verb dlps with that media code and both are of very high quality and both produce excellent results.[/I]
My Verbatim +r 8x have these serial number on the plastic hub: 4332E231304012010
