Not for CDs, here they are borked without such an issue after a short period. In the 80s I became an audio and video engineer and my career started with copying professional, high quality video tapes, since the BASF video tapes from the audiovisuellem Medienzentrum of the university Essen disunited carrier layers and magnetic layers.
