You can use the audio only cds in your computer. The recording industry decided to cash in on music stand alone recorders, so they required that these recorders look for a specific fingerprint on a cd before it would go into the record mode. We use to use the swap trick on Philips, but that is another story. That is the only difference. In fact, if you do a full erase on a audio or music only c d r w, you'll erase the special mark and it will no longer work in the recorder, so do the erasing of these c d r w music disks only in the stand alone recorder. Hope all this makes sense. 73s Butch Bussen wa0vjr
