Tdk Dvd-r 4x

Can comeone confirm these are all (not just the 5 I bought) made by TY ?

Thanks !

All those I’ve bought have been TY as well.

The ones I have are TDKG02000000
They also fail to burn.

Ooops my mistake. All the 4X certified TDK discs I have bought is TY.

That should make it clearer.

TDKG0200000 is 2X certified.

Ah , yes, the TDK I have is 2x. :o

I’ve seen reports that TDK (at least in USA) now also sells RITEKG04 discs (although I think they’re only sold as 2x media).
