That is not my understanding. I burn a CD after every new gem book, putting all the final edited image files on there as well at the PageMaker 6 layout and text. That gives me additional security against physical loss, magnetism problems, etc., and just also makes another copy to file somewhere. Everything I read says CDs last a very long time.... minimum 50 years and perhaps more than a century. There is a genuine question at the moment as to which type lasts longer.... one that is pressed from a master like all commercial products are, or one that is individually burned on a CDR machine producing one copy only. SCIENTIFIC AMERICAN did a long piece last year on CDs and other storage media for our digital present and future and as I recall it suggested that the century mark was probably right for CDs. I have never seen anything even approaching such a short time as the 20 years you mentioned. I hope for other input from others on this. Fred Ward
