A friend of mine picked up a 5-pack (of CD-Rs) at "Fry's Electronics" in Southern California. (Curiosity got the best of him) He paid $18 for the 5-pack that included oversized jewel cases. What a waste of money.

Anyway, he gave me one to try. And it is indeed made by MAM-A (Mitsui). MID is 97:27:58 (80min)

If you're really interested in trying Mitsui Gold, then don't waste your money on Memorex. Buy unbranded MAM-A here:

They also sell the 74 min "archive" version. And also the gold DVD version:

And if you're making audio CDs you can buy this version rated for burn speeds less than 12x: (MID: 97:27:55)

Or if you want to overpay (twice as much) Mobile Fidelity sells these same Mitsui "Audio Master" CD-Rs under their name:
