If anyone is familiar with the Sony MDS-W1 dual MD deck, then I would like to know the method for copying in the digital domain (non-ATRAC) by which you don't erase the source disc. This is a hi-speed (4x) copy. Someone knowledgeable had explained it to me some time ago, but I no longer have the information. I do not have have one of these and they are extremely rare, but if one shows up on Ebay, Craigslist, or wherever, I intend to acquire it. I'd like to to be ready for that day. I regret not having bought the unit when it was available. PM me or post here if you have that information. Thanks! =========== Note: I belieber I have found the answer, here: http://forums.minidisc.org/index.php?showt...mp;#entry118046 Thanks Phippeb, now if I can just find the deck!
