Mitsubishi’s selling 2 kinds of CD-Rs here in Hong Kong:
Ultra Platinum - uses Super AZO (check by media code), and
Blue Platinum - uses Metal AZO (told by shop keeper)
I used to think those super azoes are superior as they were branded “Ultra”. But I was informed by shop keepers that the “Blue” ones are better as metal azo was used. Price neither gives hint as they are the same. Can anyone tell me which is truly better, or which is better for Data, audio CD, etc?
(I know this topic has been discussed long ago - date back to 2002 - I guess time has changed now )
