Dark-Vampire

Hi, I've recorded some important conversation (e.g. Board Meeting and stuff) on my MZ-N1 and I want to copy the information on my minidisc to another media. I know digital uploading to PC is not possible and when I tried analog uploading, the sound quality was awful (I plugged the headphone output directly in the microphone input, but a lot of background noise appeared on the computer...). Is there any way I can copy information on my MD to a computer with better sound quality or could I copy it to any other media (e.g. Cassettes, CDs, etc.) Thank You, DV
