Hi Jean Luc,
It is quite possible to introduce specific error patterns into a CD during mastering. The hard part is to ensure tha these are the only errors produced or at least that the inherent error rate of the disc is sufficiently low as to keep the test disc valid.
With the advances in mastering, it is possible to produce almost perfect masters. Also injection molding has come a long way and it is also possible to produce very high quality CDs. BUT this all costs money, further each disc would probably have to be tested and certified with a resultant high reject rate.
So if the ABEX test CDs rely on artificial error patterns, perhaps the above reasons may go towards explaining their high costs.
Regards,
Bob
