Taking care to improve the quality of a CD recording and mastering would go a long way towards keeping it alive and well. Wasn't there a kind of HD series of CDs some years back that used the extra, unused portion of that last bit that went some ways to improving the sound of the CD? What happened to that?
As I've stated elsewhere, there are some damn fine CDs out there and they should all be made to the same standards.
Another thing: has there been any attempt to improve the encoding of redbook CDs that could be read by the current lenses? It seems to be a matter of QC on the part of the labels.
