DVD Identifier /More info /MediaMatch:
TTH01 is a very interesting MID code sold in Europe at least under the name TDK DVD-R 8x "ScrathProof" because I bought a lot of them.
Being scratchproof they are a little more expensive than the TTG02 with their "classical TDK blue" look
From what I know it is manufactured in this factory at Basharage in Luxembourg
TTH01 - Made in Grand DuchÃ© de Luxembourg, only ??
The TTH01 disc itself looks grey and not the "classical TDK blue" anymore
TTH01 is a very good media, it performs better than TTG02 in my NEC 3500, Pioneer A07 and LG 4163B
and it had the best overall results in the recent comprehensive tests published by the german magazine c't mag
"MediumRare" has posted a summary of these tests here:
