I use Taiyo Yuden blank CD-Rs at my mastering studio for both red book cda & referrence cdr's, for my clients.
On Taiyo Yudens...which number on the disk identifies it as an official TY...the # on front hub or the one on the edge of the back hub ???
[The # on the front hub is HL842C1011380
The # on the edge of the back hub is 80 PG7631]
I want to be able to tell my clients that I use "Taiyo Yuden _ _ _ _ _ _'s"; & am not sure which # to use.
