Just returned to my computer today and read this thread on MD copying... Pretty complete discussion but I didn't see this mentioned - For those who can afford it, there are MD decks which copy the data stream as recorded on the MD. I.e., it does NOT pass through the ATRAC decompression/compression algorithm. This produces a clone of the MD. These decks are intended for the pro market and the their prices reflect it. (You need two machines to clone a MD, of course.) See the minidisc community page (www.minidisc.org ?) for more details. Now we need a service company to dup minidiscs in this fashion.
