Next use a program like Audiograbber and select 'file', then 'line-in recording'. Click the record button and hit play on your minidisc to start recording to a wav file on your harddrive.
Unless you have a minidisc player with optical digital out and a computer with optical digital-in, you won't have perfect copies of the audio from your minidiscs, but you probably won't notice much difference using the above method anyhow. Good luck!
