There are at least three companies making discs in Singapore:
Mitsubishi Chemical: mostly HS-CD-RW, HS-DVD-RW, DVD+R DL, DVD-R DL, soon HD-DVD
Fornet: Azo CD-R
Totally unrelated to TY
mark_244: Do you have scans of those?
Those are unrelated to Mitsubishi Chemical/Verbatim, but are sold by Mitsubishi Electric instead. They are not very popular.
