Wow, we’ll actually see 48x cyanine discs from someone other than TY! Quite interesting to see how those perform…

Actually I have some very recent ritek cyanine discs from TDK that writes at 48X (smartburn off) and reads back without any damaged sectors.

Yes, I was pretty impressed.

TDK Reflex Ultra 16X…

i bought a few TDK 40x cdrs thinking they were cyanine and to my shock they were pthalocyanine crap!!:frowning:

i burnt one and cdspeed says its fine 100%. yeah right the playstation doesnt think so!! also the cdr looks a funny colour when i put it under my desk lamp, a purple blue colour, I got my old burner to write to the same cdrs and it came out a light blue colour and works fine. I also burnt at the same speed (8x).

here are the details of the cdr from fuerio

the cd is also weak compared to the cyanine cdrs. two spots of data seemed to be missing already:a

Verbatim rule the cdr kingdom, hail verbatim

Read my LTR-40125S review, the ritek type 7 discs is actually one of the few types to work 100% in all cases.
