I recently taped a show using a Sony MZ-R70. I needed to do a mini-disc swap, and I rushed it, as to not miss any of the show. Well I did not hit the stop button before I ejected and when I went to play the disc back it was blank. I know it did record because I had checked a few times, and the first minute was there, I was taping over a minute worth of testing. So that track was on there. That was track one and two, track three is the one I am trying to recover, it was about 60 minutes long. Does anybody have a clue on how to retreive this audio??
