Oh yes without doubt the easiest way is to do as j2buttonsw has explained.
And if you want to turn your cassettes into mp3s here is a nice way......connect your headphone socket on your tapedeck to the mic socket in your computer. Use a splitter connection 1plug2socket to connect to your tape deck...one is connected to you computer and the other you have your head phones in. So now you can stop the recording at the end of every song on the tape. It is laborious but gets you nice edits.
