Fujfilm, but those ones were quite old (about 7 years old)
Taiyo Yuden!
i don't think taiyo yuden were making fujifilm media at the time (i could be wrong, though). i have fuji media from around the same time and they are made by either fuji or TDK and both are made in japan. i have some sony taiyo yuden from like 6 years ago which don't have c2 errors. thus far i have ran into one defective fujifilm cd-r. it had small "holes" in the dye and if you hold the disc up you can see right through them.
as with other media, i've had mixed results with maxell. i have old maxells that are now almost totally unreadable and have a high c2 error rate, and i also have more recent maxell media which have no c2 errors.
