Make a connection between your cassette player and your computer using the RCA cables. Plug the cables into the "Line Out" jacks (left and right) on your cassette player. Plug the other end into the "Line In" jacks on your computer soundcard. These may be jacks of a different (non-RCA) configuration, so an adapter will be necessary. Those will most often be 1/8-inch jacks. Adapters are inexpensive and readily available at Radio Shack.
If you don't already have it, download and install a free copy of Audacity as your recording software. Once done, open it up. Turn on your cassette player and insert your first cassette.
Play your cassette to begin to determine recording levels within the Audacity software. You'll see the recording levels as your cassette plays. These levels can be easily adjusted to prevent unwelcome distortion in your new digital recording.
Once you're satisfied with the recording levels, rewind your cassette tape, click on the red "Record" button in Audacity and begin playing your cassette. If your original has 10 tracks, you'll probably want to maintain that--so, when track 1 finishes playing, stop your recording.
Save your first track as a .wav file, naming it as the original, or as something else if you wish. Audacity has quite a deep feature set, which allows you to edit your recording once you've finished. You don't need to go there now if you don't want to, but you can return to it at any time to clean up your new file (i.e., to address issues such as dead air, pops and clicks).
Repeat step 5 as many times as needed to capture the entire cassette digitally, then close out Audacity and open up your CD-recording software. If you don't yet have any on your computer, do a quick search online. There is a plethora of free software available for this task, and for use with a wide variety of operating systems and versions.
Once your CD-recording software is open, select the digital files you've just recorded and import them. You're going digital here, so you now have the ability to change the order of the music material from the original if you want.
Put a blank CD in your disk tray, and select the "Disc at Once" modality in your software. Record. It will let you know when it's done. Enjoy your new CD.
