Windows computer?

In that case, you have Sound Recorder built in. Run cables (RCA to 1/8", probably, ask if you need help), hit record on Sound Recorder (in Accessories|Entertainment) hit play on the cassette, and record until the music stops.

Computers that came with Creative Sound Blasters have slightly better recording applications (light versions of Cubase, Cakewalk, etc.).

Companies like www.m-audio.com and www.echoaudio.com make much better audio cards starting at about US$100.

After you have captured the audio, you will burn a CD, either with Windows XP's built in burning utility, or with Nero Burning Rom, Roxio, or some other burning program. I think Nero and Roxio also have recording programs built in.

Good luck, and let me know if I wasn't clear on anything.
