> Wow! what do record companies do with important catalogs like the Beatles? They hold on to the original analog parts, whether they be original disc recordings (like in the 30s and 40s) or analog tapes. A bigger question, what happens to ORIGINAL DIGITAL recordings. Ever buy a CD that is DDD? There's never been an analog tape in the creation of that CD. And as we see, digital tape is highly unstable as an archival medium. > The final question is, then, what IS an archival medium? The accepted norms for long term (read, hundreds of years) analog storage is disc (such as 78s, LPs, etc) and analog reel to reel tape. Both of which are known to last decades so far. Even analog tape with sticky shed syndrome can be made playable again, usually with incredible results. Dave Bradley
