There aren't 50 ways to transfer analog tapes to digital: connect your tape deck to your sound card / on-board audio, play the tapes into audio recording software, do audio clean-up if desired/necessary, cut the track into separate songs if desired, burn the resulting files.
It'll take a while. If your tape deck can play at 2X speed and you don't mind sacrificing some playback quality, then you could try your luck with recording at 2X the sample rate and change the sampling rate of the recorded waveform once done.
