1633S BS0Y and T03 media

I think this is a very bad burn at 3x speed.
If this is real TY media, why coudl it be so poor ?

Another disk writeen by the ADER test, the ADER looks better as expected.
But the BLER is still appalling.

I suppose I ought to go to the blank media section and see if these are real or fake TY media :o
