B) SafeDisc:
Like LaserLock protected CD, SafeDisc CD stores its protection in the MainChannel data of CD. This protection also uses lots of unreadable sector, which usually starts at sector 800+ and ends at sector 10000+. Unlike LaserLock protection, nothing at the surface of the CD is visible showing that there are unreadable errors.

Most of the drives we have tested can read a SafeDisc protected really FAST! All Plextor drives for example read both original and backup SafeDisc protected CD very fast! Very good choise for SafeDisc protected CD. It seems that some drives read the backup CD slight faster than the original one and some others not. Below are some results using LaserLock protected CD (original) - Euro2000 - and with "Fast skip error" mode only:

Plextor drives seems to have some problems reading from the backup CD and gives back much lower performance than Ricoh and Yamaha drives:

- Conclusion

Wherever you own a good CD reader or not for ignoring read errors, best option for SafeDisc protection (for both original and backup cds) is "Fast Skip Error"; the "Intelligent Bad sector Scanner" is not good for the most drives (even in some cases it might give you slight better results).
