[ProAudio] 90 Min CRR?

[charles]

FWIW, I have a couple of clients who desire CDs so I still do them on a very regular basis.  I have *never* had success with longer than 80-minute blanks and I am now measuring very high error rates at the ends (edges) of discs labeled as “80 minutes.”  If possible, I would not push a disc past 74 minutes, these days.  The manufacturing tolerances and quality control have plummeted in recent years with all brands I have tried.  Within 74 minutes, the error rates are still pretty decent, but I literally see an exponential rise in error rates past 74:00 and often hit E32s before 80:00.

Just a data point for you...

Chas.
