Hi, Whizzkid - you need some sort of recording software on your computer. The MAGIX Audio Cleaning Lab works well, and so do various recording packages from Roxio. You use a patch cord to connect to the "line in" jack on your computer, start the recording software, and push "play" on the cassette player.

You might want to consider getting a digital recorder to replace that cassette recorder. That will simplify and improve the process of transferring the recording to the computer. Digital recorders are getting pretty cheap these days. You can get a nice one for less than a hundred bucks.
