There might be a better way. here is the idiots view of how I would have to do it
Install something like adobe audition.(cheap on ebay)
Play and record the mini disc in it entirety onto your hard disc.
Then set about the job of editing it into songs.
Every song you'd 'save as' it s title, then throw the rest of your big recording away.
Alternatively (worth trying first)
If you can connect you md to the computer with through the USB channel - maybe your computer will be able to read the files on the mini disc like its just memory drive - in the same way it reads mp3's and cds

Then you can save as, and re- format them as you save them using windows explorer.

Anyway, that's my view.
