Short anwser... it ain't too easy...

You gotta first 'real time', 'analogue' record each track off the MD onto your hard drive... From the headphone jack OUT on the MD unit, to the Line In jack on your PCs sound-card... THis will require some kind of audio recording software like CoolEdit or some such... there are plenty of options

Then you take those recordings and using CD burning software you can burn them onto a CD, either in what ever format you recorded them in, or as CDA so they can be played on your other CD players...

The Hi-Density MD recorders are coming out with software that makes this a MUCH easier thing to do....

Good luck eh!
