HHB Gold & Silver are usually made by Mitsui (sometimes Ricoh)
MFSL Gold are made by Mitsui
Apogee Gold & Silver are probably made by Mitsui
Delkin Gold are probably made by Mitsui
Mitsui today is more known as MAM-A
Another excellent brand is Taiyo Yuden. Some (not all) Fuji & Maxell CD-R are Taiyo Yuden (but only if they say "Made in Japan" on the packaging). Or you can just buy unbranded TY discs thru on-line dealers.
I would mention Ricoh discs as well, but alas you can't find them any more (except for some HHB discs).
