I think it's OK as long as you're not exceeding the speed rating for the CD-R that you're using. If I burn discs at the full Zone-CLV 32x, they come out looking like a bullseye, and the 32x zone is significantly lighter than the other zones when using 24x media. The reduced contrast between the pits and lands in the dye increases the chances of misreads.

This disc works fine now, but will it still work in a few years? Who knows.


For that reason I only burn music CDs at 8x to improve compatibility among different players. Also, the propagation delay of the laser and its circuitry has less of an effect at slower speeds.
