Your deck probably does not have a direct input - so look for a cassette adapter (BB sells several of them). You can "play" the cassette and plug the cord into your CD player (or MP3 player, or GPS, or... just about anything!)
Be sure to set the volume on your CD a little lower otherwise you will get some distortion if you drive the adapter too loudly.
