Taiyo Yuden - Azo metal dye

I was wondering when TY started using an azo dye. I’ve seen the 8X and 16X TY media advertised with Azo in the description. I’ve never seen a description of the 4X TY’s mention Azo. Can anyone shed some light on this. Thanks.

I thought AZO was just on Verbatim (MCC) discs.

Here’s the link to the vendor advertising 8X and 16X TY’s with an ‘Azo metal dye’.

Their 4X TY’s appear to be legit based on the alphanumeric code on the disc.

Ask the seller whether they are 100% made in Japan.
