I have a portable stereo system which is permanently connected to my PC. You need a recording programme, I use LP Recorder and LP Ripper. LP Recorder will record the whole tape as one long .wav track and LP Ripper allows you to split it back to separate tracks. Both can be got from click here
Alternatively, Jetaudio is free from click here but you would probably need to record and save each track separately.
